When it would run for a short time and die and then after a few minutes it would do the same thing I knew it was probably the coil. The small wires inside the coil had a broken wire when it ran the coil would expand and the broken wire would separate and shut the power off ,when the bike sat for a few minutes the coil would cool off and the broken wire would make a connection and the bike would run. I had this issue back in the 70s on a 55 Chevrolet car I owned that was doing the same thing. After replacing the points,plugs ,carburetor and still having the same issue a old mechanic I knew told me to replace the coil and it ran like a top. He then explained what was going on with the coil. It never made sense to me before he explained it because every time it stopped running I checked the spark and it was fine because it only took a couple minutes for the coil to cool enough to work. I never forgot that lesson I learned as a young man .
I've worked for years as an electronics engineer and have seen this in coils in TV's and other equipment. LIke you say coils can connect when cold and then when the coil or transformer is under load and heating the wires expand and bring the fault. Those kind of intermittent faults can be the hardest to trace. You also get situations where two separate windings in the coil fuse when under load, so reduce the value/inductance value of the component and cause faults. But when tested cold and out of circuit the coil tests like it's ok. As I say, those faults can be very frustrating to deal with.
Reminds me of the days you could buy a $2500 2 stroke, race it all season, replace the piston and ring ($100), and be all set for next season. My how things have changed. Great video, thanks for posting.
@@squid0g Nah good pre 2005 2-strokes are still competitive. Put some good suspension on the bike if it didn't have it already and add some power to the motor with a couple easy things like reed valve and exhaust, you got yourself a race machine.
@@Tsitris46 you're not supposed to say the word old because they think we know nothing They can foam all over him I was a better mechanic at his age that's why I give him so much s*** because he f**** up so much You can say anything you want about me because I've made my living doing this stuff professionally not in the garage with more money than sense I made money doing this . If I see something he screws up and says wrong I will point it out get over it grow up get a set
@@RonaldDaub-v9yEveryone learns differently, He's learning in the age of 2024 and you learned in the age of 70s and 80s, He's doing good at teaching himself and learning, I'm for sure you started off not knowing everything, nobody does and nobody could, So he's doing just fine, And he's learning more and more everyday, What else could you ask for out of him, I'm 64 years old and in my time i was pretty good at working on Bicycles, Dirt bikes, then cars, Even to this day I've haven't had to take nothing to a shop, Or get rid of something cause I couldn't fix it, I did give up on 1 van that needed a transmission and I didn't wanna do it, I replaced a few of the solenoids and everything I could on it without pulling it, And then just gave up on it, And being a mechanic, I think that's not that bad of a record , I'm for sure I've owned 20 or 30 Vehicles in my time, In my early days i'm for sure I pulled 40/50 engines just using a tree limb in my front yard, Just learning as I go, The same thing Joe is doing now, And he's learning very well and he's learning very quickly,
I don’t even know how to ride a motorcycle and I’m so into watching his channel. It’s absolutely amazing watching him fix anything he buys and get them running again.
Same here. I grew up riding 2-cycle snowmobiles...so I enjoy watching this guy tackle these jobs. His problem-solving skills and methodical approach...he makes it all look easy.
The seller poured his heart and soul into this project and for the coil to be the issue doesn’t seem he possibly could have overlooked the coil as the culprit, so I’m guessing frustration took over that led to the sale. If only that little black box could be read like flight data recorder.
I had exactly the same issue with a Suzi DR650 a few months back, fat blue spark when testing but wouldn't run for more than a second or 2. Went through the entire fuel & electrical system, everything checked out fine so I started replacing all the electrical components 1 by 1 with known-good units from another DR & as soon as I replaced the coil it fired straight up & ran like a clock. You can't beat having a spare bike lying around!
I always find it interesting that people tend to swap coils last when tracing electrical problems. The correct way to do it is start from the plug and work your way back, not the other way around. Plug, boot, wire, coil, chassis grounds, wire harness, stator, cdi. I had a 440 race chassis snowmobile with a 700efi swapped in and the suspension was so stiff that the vibrations would make it destroy a coil every season. It’s very common they shit the bed
@@narcismo2474 Back then, (90's and earlier), MXA was a good source for technical information. It is a sales brochure today. I can "red pen" (like a teacher checking wrong answers on a students test), just about anything they write about a 2-stroke, and that "flywheel" article (how they work)!? My goodness, I understood them better as a HS student. Don't think that dysfunction is just in this sport. It is every industry today, as these kids of terrible progressive schools take their places in life.
No kidding !! I had a RM 80 when I was in high school that did the exact same thing...... Only there was no internet back then. Must have rebuilt it 3 times just hoping it would run.
You stated early on that it had to be an electrical issue and you were right, just took a little time to isolate. It amazes me that this relatively simple swap out part wasn't tried previously. Good score!
My bike died like this 15years ago at every small rain or puddle. Turns out my spark plug cap was bad 😅 Sometimes the biggest sounding issue is a small one 😁
That's a problem with OBD-1 vehicles. I threw 100's of $ of parts at an '89 Ford Bronco II. Finally brought it to a mechanic who got it to run a little better. I think ONLY the old school Ford mechanics at the stealership couldve fixed it right.
I've learned after a lot of mistakes, that electrical components can test fine . But under load it's a whole diff story ...sometimes the only way to get an answer is swap with a good know part like you did ......even then it can leave you scratching your head
I heard a best man speech once where the guy said to the bride, "there are only 2 things you need to have for a successful marriage with my brother. Duct tape and WD40. If it moves and it's not supposed to, put duct tape on it. If it isn't moving and it should, cover it with the WD." We all looked at each other and nodded and said, "yeah, what he said."
Seeing your level of advancement through the years is amazing. U used to just twist the throttle on 2strokes, now u just blip it and release, letting them run the right way.......awesome to see man
Back in 1984 my friends put an ATC axle and some flat track tires on a Honda CR80... when that thing hit high-rev it would leave the Honda ATC250R in the dust...😂 ❤
Its pretty sad when these supposed mechanics looked at it and could not get it running but you did the trial and error method to make sure something wasnt over looked but obviously something was. Good job getting it running bro. Love your videos
If there's a backlog of 20 bikes waiting to be fixed, you can't afford to spend a lot of time on one bike. Time is money. They cut their losses and move on to the next.
yep, he went through process of elimination , it had proper compression , woodruff key good not sheared etc so just like fixing lawn mowers he had to change /test everything in the electrical to get it to show
Joe, when you walk, do you tend to vear to the left? With all the kicking you do to get your bikes to start, your right leg has got to be 10 times stronger than your left.😅
It's because he needs a bike lift! Never seen anyone work at that many bikes and work on them the way he does. I would have bought a lift before a spark plug checker... just saying.
@@gags730 he first needs the shop to put it in ,I can understand that he doesn't want to put a lift in his garage, even though he has done it in a small space his whole life
Good work, half way through the video when you was looking into spark and it would cut out …. I kept saying ‘I bet it’s the coil’ lol one first things I’d check (air/fuel/spark and their components)
Joe's sheer will power and the power of the "Kicking Boot" brought it back to life. The coil is just sitting there. Add coil resistance to the list of easy things to check.
As others had said, intermittent stoppage usually is electrical. In real world mechanics keep things like cdi, coils, stators that they know work so they can quickly swap things to identify bad parts. Its weird with good compression, when Joe started engine in garage it was really smoking but not when he rode the bike later. Still entertaining video @RonaldDaub-v9y
The most impressive thing about this video is how many times you can kick it in a row without completely being gassed out. Good cardio! I'm halfway through and had to comment
This was awesome to watch. My son said carburetor within 5 minutes of the video and I said coil. We had a good laugh watching nothing fix it until the end when the culprit was found. This happened to me with a Ryobi weed wacker/wipper snipper. Had good spark would start and run for a few seconds sometimes even a few minutes then die and not want to start again. Swapped the coil for another second hand one after a lot of headache trying to figure out if it was carburetor related or spark related, anyway worked it out in the end and it's still going after 13 years now. Thanks for sharing.
After you eliminated the motor and carb, we knew it had to be electrical, I guess he didn`t want to buy a new stator, that didn`t work, then buy a new CDI, that didn`t work, next buy a new coil and he would have been a happy camper. You happened to have a 250 sitting there to swap out parts, saved a whole lot of money, I tell you what, that guy could rebuild my bike any day of the week, the rebuild and carb were spot on, that motor screams. I always had 125`s, I weigh 155 lbs, I borrowed my buddies 250 CR once and I couldn`t keep the front wheel on the ground, they have a ton of power, well done sir.
Man I was yelling at the TV to check float level and coil. Lol learned my lesson along time ago just because it sparks outside doesn't mean it sparks once under compression.
Really enjoyed that. I ride bikes on the road but next to nothing about engines and I'm 40 years old now. Only bits I have learned have been where things have gone wrong with bikes I have owned in the past and watched friends work on them or they have gone to a garage. Wonderful to watch you troubleshoot and find the issue. I have learned a lot through this video, I would never have thought you could get a spark and the issue still be a coil?
I sheared a woodruff key years ago on an IT200, she still fired up but was running backwards, i'll never forget when I let off the clutch and started going backwards 😂
I had a rd 400 that would do that because of a weird aftermarket ignition system. First time I did it I almost went over the bars when I let out the clutch! Then I found that a half kick would start it running backwards every time! It always was a fun trick to mess with people!
Listen to that suspension squeak. We always get engine rebuild videos, but I would like Joe to rebuild the forks and replace the suspension bushings on some of these old bikes. It's expensive to have the work done and it would be good content for the viewers that have older bikes.
@@joeshafer83 I'm wearing headphones and can still hear the creaking and squeaking when he's on the pavement outside. The acoustics in his garage just makes it more audible when he's kicking on it later in the vid. For sure sounds like bushings to my ears.
Wow. I could have saved you all that work. I had a 90 cr500 same problem. I put $$$$$ into the bike. It would run fine and then nothing. First thing I said to my wife it's the coil! It's the coil.😅 50:58
That creaking at the swingarm pivot is driving me crazy. I'll never understand how people could let bearings get so dry. A long time ago, I purchased a 1993 YZ 125 with a cracked swingarm. I had a friend weld it up nicely for me and after the first ride it cracked again. Turns out the swingarm bearings were seized causing the swingarm to take all of the pivoting heat. That was a lesson well learned as to why it's so important to keep all of the bearings greased and functioning properly.
My guess is when the coil started to get warm it failed. Love the sound of those 2 stroke dirt bikes. Watching you ride with the camera brought back great memories. I'm just not used to liquid-cooled 2 strokes.
I have seen the sleeve in an air cooled 2 stroke spin and block the ports part way. Acted the same way , just quit wouldn't start. I think those late 80s CRs are a tough looking bike !
Love all your videos qnd i dont even have a dirtbike anymore lol. Just one thing i ask...if you ever read this, please wear EAR PLUGS at least in the garage...will save your hearing for the future. Keep em coming, you are the man!
I wish that i could have seen this video around 17 years ago when i was troubbleshooting my Yamaha moped that went from running perfect to having the same problem that this bike had. Great job 👍
My guess is an electrical problem or timing issue. We shall see and this should be interesting. Wow, half way through and I am a bit stumped. China spark plug? Hmmm, coil? Dang! It was the coil and it still had spark? I dunno, scratchin' my head.........how can that be? THIS IS A GREAT CHANNEL!!!
@@mr.shhnow6294 I never said anything about a timing chain but a 2 stroke does have timing based on a relation to top dead center of the piston. So what's your point?
@@mr.shhnow6294 Dude! Go find someone else to be an ass*ole to that actually gives a sh*t about what you have to say while you sit in your armchair eating chips and getting crumbs on the t-shirt you have been wearing for a month!
You are a hard worker. Thanks for fixing that bike. My brother had a kx 80 and that was fun to ride. We used to talk about the power band and ride it around.
Spark under pressure is different from outside combustion chamber in older cars very common coil packs show spark but misfire when under load plus u had strong compression probably giving false causal! Fair play to you for working it out
@@scudger99aaaahh, in the hope that he ups his game. Throwing parts at it is the amateur’s approach to fault diagnosis. Joe has experience and tenacity, lacking in electrical fault diagnosis training, that’s all. The thing is with mechanics, electronics and electrics is the weak area with most mechanics…. Some just can’t get there head around it at all.
@@munter10 It's not exactly the sort of thing I see advertised every day "electronics diagnosis courses for mechanics". Where would you go for that training, unless you took a job and learned on the hoof ? I am an engineer of a different sort, and the "swap loads of parts out until you sort it" is the approach my employer pushes on us. Otherwise it means training guys to the required standard, and that costs money.
Sometimes, in anything with windings, there could be a break or damage that when cold makes contact, but as things warm up and expand just a little, the contact is broken.
@@RonaldDaub-v9y I don't see him being grandiose, never heard Joe claiming he was great or superior. He's learning as he goes, the bad coil lesson here will stick. FWIW, coil quality has been declining over the last couple decades, as copper prices have increased and more OEM and aftermarket component manufacturing has moved out from Japan, to China/Vietnam/India/etc. They tend to use slightly thinner gauge wire in the windings (as thin as they can get away with, and the coil still work) to save some costs over 1000's of units produced. That thinner wire tends to fail sooner due to vibration, and is much more vulnerable to thermal issues and overcurrent spikes. This another example of why they say "they don't make them like they used to"...because, race to the bottom (dollar).
@@RonaldDaub-v9y I've never heard him bragging on himself. I do see alot of people in the comments commending him and telling him how great he is. Maybe your conflating how the people view him, vs how he sees himself. I personally find his videos to be quite inspiring. And I commend is hard work and dedication to fixing the projects he chooses to take on
@@2Smoke-AClae47 that's why I know I've done this for 55 years I also do cars and I still am working. I just simply see him and making stupid mistakes most mechanics would not make and saying things like nobody could fix it except me nobody says that in the motorcycle industry that has any brains nobody is proud of themselves or should not be that all I'm saying. I see a grandiose person that can fix things with a lot of money and that's fine but he's not the god or the best maybe he's teaching you something God forbid
@RonaldDaub-v9y I think you may have a personal biased against him. I've watched alot of his videos, and I've never once heard him claim he was the only one to be able to fix a bike, and I don't really see him throw money at bikes. Like this one for example he used parts off a bike too see if it would fix the problem if he was made of money would not just buy brand new parts. I see tons of guys on RUclips that will buy a bike for 2500 then sink 12000 into it. Now please correct me if I'm wrong, this is purely speculation, but I get the sense your abit jealous of him. He seems quite happy doing what he's doin. It seems to be a passion project for him. I assume he has no formal training, so he just learns as he goes. You haven't presented any real evidence to back up your claim. It just seems like a trust me bro moment. It just seems kinda weird to tear a guy down for no apparent reason unless it's jealousy
Grab an inline spark tester, they're very cheap but would've been absolutely priceless for this situation as you can observe what's happening to the spark while everything is still hooked up. A bad coil will typically work until it gets warm then shuts down. Great learning experience though, nice job getting it running!!
@@JEGsGarage yeah, they're real cheap too. Stayed in the drawer for a couple years until I had an old Ford come into the shop, it would die after a couple minutes so I figured it was the coil but didn't want to throw parts at it. Remembered I had that tool and was able to confirm it instantly.
Reminds me of growing up in the Midwest long before cell phones. It was a beautiful sound to hear. Everyone had dirt bikes and go-carts and its all we did all summer. Kids today are truly missing out. Most of where I grew up is all built up now, houses everywhere and few places to ride.
At the risk of sounding like an armchair expert…a little squirt bottle with premix could possibly speed up the troubleshooting process. At least that would be my (and my late grandfathers) approach to something like this
@@RonaldDaub-v9y my intent wasn’t to tell anyone. I have learned that I am definitely not always right…but I just wanted to mention it, for those who might find it helpful. This channel is exceptional. Joe really does a good job of staying neutral, not getting emotional, no gimmicks, just his own approach. I appreciate this approach greatly, but that doesn’t mean I don’t question it sometimes :)
At 36:00 I was thinking loose coil ground, so I waited to see if you were going to show swapping out the coil to see if the ground screw was loose, but you didn't show it. Sketchy, open ground would explain the intermittent spark. Anyway, good work and good looking CR
Your bike will start easier if you don't wing the throttle as you are kicking it. Try holding the front brake lever as you kick to the slide stays in one position. I'm 76 years old and have been riding big bore 2 strokes since 1984. I have 3 big bore 2 stokes and one CR250 that my daughter rides. Glad you got it running!
You can't blame him too much. What he said he did do was correct. Sadly most people tend to stop at fuel and compression but forget to check what makes the magic happen. It must have been the fact that the bike had a great spark yet didn't want to run. So he was stumped with its' symptoms.
@@Slane583 Yeah, that fat spark did indicate the coil was good. My first guess was the kill switch shorting out from vibration, but that was because of personal bias. I repair PCs, and had several come in because of apparent 'thermal shutdown' under increased load, but it was actually the power switch gone bad. But the switch 'worked fine' to power the PC on, so THAT couldn't be the problem, right? However, the slight vibrations from the case fans ramping up under load would eventually cause the faulty switch to short at various intervals and power down the rig. My first check with this symptom is to unplug the power switch and short the pins on the mobo to boot the PC. The symptoms are often deceptive, so eliminating the super easy fix first has saved me many hours of pointless troubleshooting. Having known good parts to swap out is invaluable. Indeed, two is one, and one is none. I love watching the process of diagnosing these machines.
@@jameshanna8762 Trouble shooting is a pain for sure but rewarding when the problem is finally solved. I build pc's for fun when the funds allow. My nephews friend brought his gaming pc over to my older brothers house sometime last month because it was acting up on him. So my nephew and him gave their hand at problem solving for their first time. When I found out I offered to help them out. We did some tests and in the end we found out it was thermal throttling while it was being stressed. So it would black screen and shut off. Whoever the previous owner was that built the computer before he bought it put the cheapest heatsink on it they could get their hands on. It wasn't powerful enough so the computer would over heat every time he tried playing his games. Since it's an older Ryzen system I happened to still have my old Wraith Prism cooler from my 3700X and installed that with some fresh thermal paste. Since he was only a young teen and saved for the summer to get that computer I just let him have the heatsink. It was no loss to me. His computer has been fine ever since.
I never trust any aftermarket electrical part (from experience lol). You get usually one of two things that happens when you don't go OEM for electrical. 1: You get a faulty part out of the box. 2: It will work out of the box but will fail shortly down the road. When scenario 2 happens, you are left scratching your head because "There is no possible way it could be the part/s I just replaced 3 months ago" lol.
@@calebhohneke8482 absolutely man it brings so much confusion to the people that don't really know, that's why it's important to go OEM or very close to it as possible otherwise you'll have people chasing their tail not understanding what's going on.
Had an '86 trx 250r. Ran when bought, misfired, fouled plugs. The more a replaced, the worse it ran until eventually wouldn't crank. Puzzled 3 mechanics until one tried a handlebar switch off another bike. Ran like a champ. Nice to have a working bike to try and see before buying.
Well done man, I know nothing about bikes, don’t even ride but this was amazing, very well done!!! Hope the dude who sold it doesn’t see this, Kudos from the UK 🇬🇧
I've actually learned something from watching these videos, when the bike started and got warm and shut down and then only ran for short bursts afterwards I guessed that it was probably the coil. RUclips certified mech. Lol love your videos
Great video. When ever I think there is a spark issue I always use a in line spark lead to spark plug tester it will show if your losing spark. Keep up the good work.
When he makes the claim that nobody can fix it every mechanic under the firmament has tried it but The godly Joe mechanic is going to fix it yeah I'm sure he will get it running but he tells a big bulshit of story you believe everything he says I feel sorry for you.
Joe prolly won’t answer, but just to the riding community out there, can you turn a profit on older bikes like these? I don’t mean basket cases I mean bikes that run but need some work. Thanks!
Depends on the location. I'm in New England, and you can still find older bikes that run good for cheap money if you keep your eyes open somewhat easily. With that said, these "specialty" bikes are a hard sell to everyone except the very few people who like this sort of thing, and even then, it'll take some flexibility in price.
Depends on location and what you buy. You can find deals but you have to know what you’re looking for and if parts are available. I don’t do it to turn a profit but purely try to break even or do it for fun
I had the exact same problem on my old HD. Would start, run a bit (rough) and then cut out. Its a process of elimination, fuel, spark, coil....new coil resolved the problem!
Joe loves kicking a dead horse as well as keep riding a bike for multiple laps when a mechanic's ears know it's not right.Better get himself some left side start bikes before his right leg dies
welp... looks like the one thing i haven't changed out (the coil) as far as electrical on my 85 cr125 may also be my issue... been battling her for a few years now... lol. If in fact it is... i'll be sending some love your way bud. Well done sir!!!
Bullshit. I've done this for 60 years and it's not just motorcycles it's everything and there is no way any mechanic worth anything would say nobody can fix anything .. I have learned over the years that anything if you want to fix it can be fixed no matter what you have to do so.
But you're going to get it running I know stop with the diatribe I know you believe the lies about nobody can fix it but you ....😂 Do you know the word grandiosity ?
you've given me hope to fix my hondra cfr150 dirt bike. I may not have all the tools, but it I can Identify the problem. I will save a bunch of cash. Very good video!!! My problem is the kick start wont kick. I will update as I look for the problem. Thanks!!
I now believe my education is complete. I have watched a ton of your videos and the stator and the coil were the last parts I haven't seen need to be replaced to get the project running. These videos teach without ever having to have the misfortune to be in a bad spot. I knew it was an electrical problem pretty fast but once it wasn't the CDI I couldn't figure it out. The spark fooled me as well and I was lost. Joe always gets the job done.
Wow, nice job. I hope you contact the owner. And told him the easy fixed you this Problem. Yes, it took hours, but at least you solved the problemi. Can't wait to see the next video. How you're going to fix your other one I do like 2 strokes. I used to ride 2 strokes back in the 70s and 80s.
My Dad told me 99% of problems with bikes or cars are caused by electrical issues. half way through this vid I'm screaming swap the coil out .Don't worry about fueling and carbs and that shit. I had a Kawasaki Z200 in the 80's and a Triumph Scrambler new in 2006 both bikes had coil problems, and both bikes behaved differently. Great vid tough very interesting, keep up the great work 👍
Ran my own shop and I had known good S.P. coils, stators, and other parts sitting on a diagnostic shelf for most popular dirt bikes, sport bikes just to do the" check the easy stuff first" kind of parts swaps. Saved hours of diagnostics and lots of $$ for my clients. Simple is not always simple. Time is $$. Good job in any case. Solved the problem which is what counts in the end!
I'm working on a recently rebuilt CR80. Ran great about 10 hours customer said. Now it dies out when it gets warmed up. Smokes like crazy. The crank seal on the oil side is the problem 😊. If it burns gas I can fix it is my motto. 😊❤
Aside from visual inspection of that which is visible and making sure connections are getting good contact, always work from the spark plug back, swapping simplest parts first. Woulda saved you a lot of time in this one. But as long as you enjoy the process...! Plus, now you know that the case seal area has been worked for some reason. When you pulled that, I thought there's no way that is ok. But it sure seems ok now! Excellent work, chap!
Reminds me of my childhood, dad got us kids into dirt bikes at young ages, had our own track that developed over time wi many riders contributing to the natural buildup of banked corners and jumps. I had a great upbringing, constantly challenged and inspired by dad....
I had a CR250 as my 1st road bike when i was young. Had it on a Q plate in the UK, was an absolute monster and still regret getting rid of it to this day.
The cr 500 had similar problems back in the day we found valve issues and back feed to the coil. Ps you are extremely brave try to 🦵 without boot on. We stole a coil from a Kawasaki 500 and it fixed the spark issue and had a vw machine shop due the valves. Good luck bro 😎
i just got a 2018 polaris 570 crew because everyone and their brother and all their mechanics swore up and down it just needed a fuel regulator. After some short diagnostic and fuel pressure testing i determined the coil pack was junk and 100 dollars later it was fixed and running. 10k polaris for 4500 bucks. Cant beat it and i see stuff like that on marketplace literally everyday.
When it would run for a short time and die and then after a few minutes it would do the same thing I knew it was probably the coil. The small wires inside the coil had a broken wire when it ran the coil would expand and the broken wire would separate and shut the power off ,when the bike sat for a few minutes the coil would cool off and the broken wire would make a connection and the bike would run. I had this issue back in the 70s on a 55 Chevrolet car I owned that was doing the same thing. After replacing the points,plugs ,carburetor and still having the same issue a old mechanic I knew told me to replace the coil and it ran like a top. He then explained what was going on with the coil. It never made sense to me before he explained it because every time it stopped running I checked the spark and it was fine because it only took a couple minutes for the coil to cool enough to work. I never forgot that lesson I learned as a young man .
im glad i came across your mnessage. im sure someday that will happen to my old bike😁
Same, but it was a condenser wire.
I had a fault like that on a Russian sidecar .The carb parts made of brass would do that on a hot day .
I've worked for years as an electronics engineer and have seen this in coils in TV's and other equipment. LIke you say coils can connect when cold and then when the coil or transformer is under load and heating the wires expand and bring the fault. Those kind of intermittent faults can be the hardest to trace. You also get situations where two separate windings in the coil fuse when under load, so reduce the value/inductance value of the component and cause faults. But when tested cold and out of circuit the coil tests like it's ok. As I say, those faults can be very frustrating to deal with.
Dude , you only wrote this comment cuz your a complete badass ! Thanks for sharing wisdom Bro..
I’ve worked on Hondas for 35 years and I can only remember replacing maybe 2 coils? This is what keeps us mechanics humble. Thanks for sharing.
Reminds me of the days you could buy a $2500 2 stroke, race it all season, replace the piston and ring ($100), and be all set for next season. My how things have changed. Great video, thanks for posting.
If ur willing to be at a disadvantage and limit urself to pre 2005 2 strokes, you can still do that!
@@squid0g I’m sorry - I meant “new” 2 stroke for $2500.
It’s all about keeping owners paying off parts
@@squid0g Nah good pre 2005 2-strokes are still competitive. Put some good suspension on the bike if it didn't have it already and add some power to the motor with a couple easy things like reed valve and exhaust, you got yourself a race machine.
Still can! (Thank goodness for like minded people filling the evo class)
Your durability on that kick starter is profound. Awesome job. So satisfying to watch your success
No offense but if 3 mechanics couldn’t fix it, and a backyard guy did, 3 mechanics need to find a new line of work.
I'm offended.......but seriously, so many "professional techs" do not want mysteries. They want to swap parts, change oil, and get the bike out quick.
Totally agree.
A backyard mechanic with a flywheel puller and a spark plug tester? No offense but backyard mechanics don't have those tools.
It's incredible how many steps it took to get back to the most basic part, a freaking coil.
@@LordHolleyso very true.
I was told by an old mechanic that if an issue appears out of nowhere and it makes no sense-it's usually electronic/electrical.

I was screaming coil so loud and so long that my dog left the room. Lol
yep, but did you also see the ngk new plug wasnt good and trying to mask the real problem
Also iridium spark plugs don't make good spark, especially on 2-stroke bikes.
They are overall not recommended.
Me too!
dog was thinking “yeah no shit genius, but if he did it your way he’d have a 2 minute video”
I knew it was a coil simple things people miss
I don’t even know how to ride a motorcycle and I’m so into watching his channel. It’s absolutely amazing watching him fix anything he buys and get them running again.
Same here. I grew up riding 2-cycle snowmobiles...so I enjoy watching this guy tackle these jobs. His problem-solving skills and methodical approach...he makes it all look easy.
The seller poured his heart and soul into this project and for the coil to be the issue doesn’t seem he possibly could have overlooked the coil as the culprit, so I’m guessing frustration took over that led to the sale. If only that little black box could be read like flight data recorder.
You can't fix what you own you should only own toys that are under warranty
The previous hobbyists were clearly not mechanics by any acceptable standard! lol
I had exactly the same issue with a Suzi DR650 a few months back, fat blue spark when testing but wouldn't run for more than a second or 2.
Went through the entire fuel & electrical system, everything checked out fine so I started replacing all the electrical components 1 by 1 with known-good units from another DR & as soon as I replaced the coil it fired straight up & ran like a clock.
You can't beat having a spare bike lying around!
The spark if it's to blue it's a no go it's gotta be mixed red and blue
Awesome!
No dude the problem was it was a Suzuki dr650
I always find it interesting that people tend to swap coils last when tracing electrical problems. The correct way to do it is start from the plug and work your way back, not the other way around. Plug, boot, wire, coil, chassis grounds, wire harness, stator, cdi. I had a 440 race chassis snowmobile with a 700efi swapped in and the suspension was so stiff that the vibrations would make it destroy a coil every season. It’s very common they shit the bed
You had spark with no compression snuffing it out.
Man i wish i could have watched videos like these in the 90's
Me too, I had copies of motocross action and dirtbike that were stacked to the rafters. 👍
@@narcismo2474 Back then, (90's and earlier), MXA was a good source for technical information. It is a sales brochure today. I can "red pen" (like a teacher checking wrong answers on a students test), just about anything they write about a 2-stroke, and that "flywheel" article (how they work)!? My goodness, I understood them better as a HS student. Don't think that dysfunction is just in this sport. It is every industry today, as these kids of terrible progressive schools take their places in life.
No kidding !! I had a RM 80 when I was in high school that did the exact same thing...... Only there was no internet back then. Must have rebuilt it 3 times just hoping it would run.
80’s for me
Coil?
You stated early on that it had to be an electrical issue and you were right, just took a little time to isolate. It amazes me that this relatively simple swap out part wasn't tried previously. Good score!
My bike died like this 15years ago at every small rain or puddle. Turns out my spark plug cap was bad 😅
Sometimes the biggest sounding issue is a small one 😁
Yep, better check the silencer again though…just to be sure that everything around it is still silent, while not running.
That's a problem with OBD-1 vehicles. I threw 100's of $ of parts at an '89 Ford Bronco II. Finally brought it to a mechanic who got it to run a little better. I think ONLY the old school Ford mechanics at the stealership couldve fixed it right.
Amazing how you diagnosed the issue through a process of elimination. Well done and a superb bike.
Watched the whole video. As someone who isn't a master mechanic, I appreciate the way you talk through the process of your thinking. Great video.
Got a stack of coils in a box all newer. Most did the same thing. Electrical components can be hit or miss, depending on what it is. Great job.
I've learned after a lot of mistakes, that electrical components can test fine . But under load it's a whole diff story ...sometimes the only way to get an answer is swap with a good know part like you did ......even then it can leave you scratching your head
Previous Owner: _3 Mechanics cannot get it to run_
Joe: _Hold My can of WD40_ .
😂😂😂😂
Keyway flywheel busted
🤣 When i first started watching his videos forever ago i would always think to myself. "Man this dude puts WD-40 on literally everything lol".
I heard a best man speech once where the guy said to the bride, "there are only 2 things you need to have for a successful marriage with my brother. Duct tape and WD40. If it moves and it's not supposed to, put duct tape on it. If it isn't moving and it should, cover it with the WD." We all looked at each other and nodded and said, "yeah, what he said."
What does it take for this guy to get a Bike Lift?
Brilliant vid. Its very common that a coil appears to work but stops working quickly under load. Bike sounds great in the end.
Seeing your level of advancement through the years is amazing. U used to just twist the throttle on 2strokes, now u just blip it and release, letting them run the right way.......awesome to see man
Man... that sound brings me right back to my childhood.
It’s magical, Right?!✌️
Back in 1984 my friends put an ATC axle and some flat track tires on a Honda CR80... when that thing hit high-rev it would leave the Honda ATC250R in the dust...😂 ❤
Same. Instantly transported. Feels like I heard this just yesterday, but it's been 30 years.
i can smell it...
Its pretty sad when these supposed mechanics looked at it and could not get it running but you did the trial and error method to make sure something wasnt over looked but obviously something was. Good job getting it running bro. Love your videos
If there's a backlog of 20 bikes waiting to be fixed, you can't afford to spend a lot of time on one bike. Time is money. They cut their losses and move on to the next.
My guessing is TIME, in my experience most shops are assembly lines, get then out the door. More than an hour total - forget it

It's because he needs a bike lift! Never seen anyone work at that many bikes and work on them the way he does. I would have bought a lift before a spark plug checker... just saying.

Good work, half way through the video when you was looking into spark and it would cut out …. I kept saying ‘I bet it’s the coil’ lol one first things I’d check (air/fuel/spark and their components)
Got 97 cr250 in pieces in my garage, your vid is making want to put it back together 😊
Joe's sheer will power and the power of the "Kicking Boot" brought it back to life. The coil is just sitting there. Add coil resistance to the list of easy things to check.
@@Poppinwheeeeellllllieeeeez ohms
As others had said, intermittent stoppage usually is electrical. In real world mechanics keep things like cdi, coils, stators that they know work so they can quickly swap things to identify bad parts. Its weird with good compression, when Joe started engine in garage it was really smoking but not when he rode the bike later. Still entertaining video @RonaldDaub-v9y

The most impressive thing about this video is how many times you can kick it in a row without completely being gassed out. Good cardio! I'm halfway through and had to comment
This was awesome to watch. My son said carburetor within 5 minutes of the video and I said coil. We had a good laugh watching nothing fix it until the end when the culprit was found. This happened to me with a Ryobi weed wacker/wipper snipper. Had good spark would start and run for a few seconds sometimes even a few minutes then die and not want to start again. Swapped the coil for another second hand one after a lot of headache trying to figure out if it was carburetor related or spark related, anyway worked it out in the end and it's still going after 13 years now. Thanks for sharing.
Joe is the ultimate mechanical genius. I’ve never seen him give up on a project, nor fail at a project.
Apart from the mini bike that caught fire 😂
the one he buried in the bqck yqrd
The air boat thing
Hes turned a few into parts bikes
Love that you know the failed projects like the buried one! 😂😂😂
After you eliminated the motor and carb, we knew it had to be electrical, I guess he didn`t want to buy a new stator, that didn`t work, then buy a new CDI, that didn`t work, next buy a new coil and he would have been a happy camper. You happened to have a 250 sitting there to swap out parts, saved a whole lot of money, I tell you what, that guy could rebuild my bike any day of the week, the rebuild and carb were spot on, that motor screams. I always had 125`s, I weigh 155 lbs, I borrowed my buddies 250 CR once and I couldn`t keep the front wheel on the ground, they have a ton of power, well done sir.
Man I was yelling at the TV to check float level and coil. Lol learned my lesson along time ago just because it sparks outside doesn't mean it sparks once under compression.
😂😂 had me craking
Really enjoyed that. I ride bikes on the road but next to nothing about engines and I'm 40 years old now. Only bits I have learned have been where things have gone wrong with bikes I have owned in the past and watched friends work on them or they have gone to a garage.
Wonderful to watch you troubleshoot and find the issue. I have learned a lot through this video, I would never have thought you could get a spark and the issue still be a coil?
Replace the CDI was my first thought… great job! Trying to troubleshoot motorcycles can be so frustrating! Very rewarding when you nail it!

Listen to that suspension squeak. We always get engine rebuild videos, but I would like Joe to rebuild the forks and replace the suspension bushings on some of these old bikes. It's expensive to have the work done and it would be good content for the viewers that have older bikes.
To me it sounded more like the new tire against the floor.
@@HOZENBIGI disagree, that's mostly bushing and pivots squeaking, with only a little tire squeak if any.
3:30 into yhe video he's on pavement trying to start it. Not a single squeak. The squeaks u hear later are all tires on floor
@@joeshafer83 I'm wearing headphones and can still hear the creaking and squeaking when he's on the pavement outside. The acoustics in his garage just makes it more audible when he's kicking on it later in the vid. For sure sounds like bushings to my ears.
wont hear it when the bike runs lol
Wow. I could have saved you all that work. I had a 90 cr500 same problem. I put $$$$$ into the bike. It would run fine and then nothing. First thing I said to my wife it's the coil! It's the coil.😅 50:58
That creaking at the swingarm pivot is driving me crazy. I'll never understand how people could let bearings get so dry. A long time ago, I purchased a 1993 YZ 125 with a cracked swingarm. I had a friend weld it up nicely for me and after the first ride it cracked again. Turns out the swingarm bearings were seized causing the swingarm to take all of the pivoting heat. That was a lesson well learned as to why it's so important to keep all of the bearings greased and functioning properly.
My guess is when the coil started to get warm it failed. Love the sound of those 2 stroke dirt bikes. Watching you ride with the camera brought back great memories. I'm just not used to liquid-cooled 2 strokes.
I have seen the sleeve in an air cooled 2 stroke spin and block the ports part way. Acted the same way , just quit wouldn't start. I think those late 80s CRs are a tough looking bike !
Love all your videos qnd i dont even have a dirtbike anymore lol. Just one thing i ask...if you ever read this, please wear EAR PLUGS at least in the garage...will save your hearing for the future.

I wish that i could have seen this video around 17 years ago when i was troubbleshooting my Yamaha moped that went from running perfect to having the same problem that this bike had. Great job 👍
My guess is an electrical problem or timing issue. We shall see and this should be interesting.

You get the most patient man in the world trophy.
Spark under pressure is different from outside combustion chamber in older cars very common coil packs show spark but misfire when under load plus u had strong compression probably giving false causal! Fair play to you for working it out
This was a quite relaxing video, great result too, always great to see a true mechanic diagnosing faults with a success at the end.

Throwing parts at it is the amateur’s approach to fault diagnosis.
Joe has experience and tenacity, lacking in electrical fault diagnosis training, that’s all.
The thing is with mechanics, electronics and electrics is the weak area with most mechanics…. Some just can’t get there head around it at all.
@@munter10 It's not exactly the sort of thing I see advertised every day "electronics diagnosis courses for mechanics". Where would you go for that training, unless you took a job and learned on the hoof ?
I am an engineer of a different sort, and the "swap loads of parts out until you sort it" is the approach my employer pushes on us.
Otherwise it means training guys to the required standard, and that costs money.
@@scudger99 It's amusing you know comedy style.
An in line spark tester would be very helpful in this situation.
Was thinking the same thing. He should have had a timing light or something if he believed spark was dying, would have told him Right away.
Yep, it was too hard to start so needed to see spark. With that you would know coil.
Sometimes, in anything with windings, there could be a break or damage that when cold makes contact, but as things warm up and expand just a little, the contact is broken.
He's too busy bragging on himself to understand things like that but you are correct and this guy is a grandiose beyond belief
@@RonaldDaub-v9y I don't see him being grandiose, never heard Joe claiming he was great or superior. He's learning as he goes, the bad coil lesson here will stick.
FWIW, coil quality has been declining over the last couple decades, as copper prices have increased and more OEM and aftermarket component manufacturing has moved out from Japan, to China/Vietnam/India/etc. They tend to use slightly thinner gauge wire in the windings (as thin as they can get away with, and the coil still work) to save some costs over 1000's of units produced. That thinner wire tends to fail sooner due to vibration, and is much more vulnerable to thermal issues and overcurrent spikes.
This another example of why they say "they don't make them like they used to"...because, race to the bottom (dollar).
@@RonaldDaub-v9y I've never heard him bragging on himself. I do see alot of people in the comments commending him and telling him how great he is.

I see a grandiose person that can fix things with a lot of money and that's fine but he's not the god or the best maybe he's teaching you something God forbid
@RonaldDaub-v9y I think you may have a personal biased against him. I've watched alot of his videos, and I've never once heard him claim he was the only one to be able to fix a bike, and I don't really see him throw money at bikes. Like this one for example he used parts off a bike too see if it would fix the problem if he was made of money would not just buy brand new parts. I see tons of guys on RUclips that will buy a bike for 2500 then sink 12000 into it. Now please correct me if I'm wrong, this is purely speculation, but I get the sense your abit jealous of him. He seems quite happy doing what he's doin. It seems to be a passion project for him. I assume he has no formal training, so he just learns as he goes. You haven't presented any real evidence to back up your claim. It just seems like a trust me bro moment. It just seems kinda weird to tear a guy down for no apparent reason unless it's jealousy
Grab an inline spark tester, they're very cheap but would've been absolutely priceless for this situation as you can observe what's happening to the spark while everything is still hooked up. A bad coil will typically work until it gets warm then shuts down. Great learning experience though, nice job getting it running!!
I was thinking the EXACT same thing! Inline spark tester would have told the tale almost immediately.
@@JEGsGarage yeah, they're real cheap too. Stayed in the drawer for a couple years until I had an old Ford come into the shop, it would die after a couple minutes so I figured it was the coil but didn't want to throw parts at it. Remembered I had that tool and was able to confirm it instantly.
Reminds me of growing up in the Midwest long before cell phones. It was a beautiful sound to hear. Everyone had dirt bikes and go-carts and its all we did all summer. Kids today are truly missing out. Most of where I grew up is all built up now, houses everywhere and few places to ride.
At the risk of sounding like an armchair expert…a little squirt bottle with premix could possibly speed up the troubleshooting process. At least that would be my (and my late grandfathers) approach to something like this

Your bike will start easier if you don't wing the throttle as you are kicking it. Try holding the front brake lever as you kick to the slide stays in one position.

Never take a sellers word concerning their troubleshooting. Start over and do your own troubleshooting.
Electricity 101:....NEVER trust anyone saying a Circuit is "DEAD"... Verify and Ground it yourself...!
You can't blame him too much. What he said he did do was correct. Sadly most people tend to stop at fuel and compression but forget to check what makes the magic happen. It must have been the fact that the bike had a great spark yet didn't want to run. So he was stumped with its' symptoms.
@@Slane583 Yeah, that fat spark did indicate the coil was good. My first guess was the kill switch shorting out from vibration, but that was because of personal bias. I repair PCs, and had several come in because of apparent 'thermal shutdown' under increased load, but it was actually the power switch gone bad. But the switch 'worked fine' to power the PC on, so THAT couldn't be the problem, right? However, the slight vibrations from the case fans ramping up under load would eventually cause the faulty switch to short at various intervals and power down the rig. My first check with this symptom is to unplug the power switch and short the pins on the mobo to boot the PC. The symptoms are often deceptive, so eliminating the super easy fix first has saved me many hours of pointless troubleshooting.
Having known good parts to swap out is invaluable. Indeed, two is one, and one is none. I love watching the process of diagnosing these machines.
@@jameshanna8762 Trouble shooting is a pain for sure but rewarding when the problem is finally solved. I build pc's for fun when the funds allow. My nephews friend brought his gaming pc over to my older brothers house sometime last month because it was acting up on him. So my nephew and him gave their hand at problem solving for their first time. When I found out I offered to help them out.
We did some tests and in the end we found out it was thermal throttling while it was being stressed. So it would black screen and shut off. Whoever the previous owner was that built the computer before he bought it put the cheapest heatsink on it they could get their hands on. It wasn't powerful enough so the computer would over heat every time he tried playing his games.
Since it's an older Ryzen system I happened to still have my old Wraith Prism cooler from my 3700X and installed that with some fresh thermal paste. Since he was only a young teen and saved for the summer to get that computer I just let him have the heatsink. It was no loss to me. His computer has been fine ever since.
To seller's credit, everything he said was true.
I never trust aftermarket electrical parts I always go to OEM and usually never have issues with faulty parts..
I never trust any aftermarket electrical part (from experience lol). You get usually one of two things that happens when you don't go OEM for electrical. 1: You get a faulty part out of the box. 2: It will work out of the box but will fail shortly down the road.
When scenario 2 happens, you are left scratching your head because "There is no possible way it could be the part/s I just replaced 3 months ago" lol.

He could easily make $1000 or more on every one the bikes he fixes.
Depends on the location. I'm in New England, and you can still find older bikes that run good for cheap money if you keep your eyes open somewhat easily. With that said, these "specialty" bikes are a hard sell to everyone except the very few people who like this sort of thing, and even then, it'll take some flexibility in price.
Haven't watched end..I'm guessing sheared woodruff key just from the intro. Those are new renthals so I'm guessing the seller embellished what he did
Depends on location and what you buy. You can find deals but you have to know what you’re looking for and if parts are available. I don’t do it to turn a profit but purely try to break even or do it for fun

Joe loves kicking a dead horse as well as keep riding a bike for multiple laps when a mechanic's ears know it's not right.Better get himself some left side start bikes before his right leg dies
Yet you still watch and comment 🤔
You can ohms test a coil to check if it is good. I'm surprised that the other guys' mechanics didn't check that. Good job on that repair.
welp... looks like the one thing i haven't changed out (the coil) as far as electrical on my 85 cr125 may also be my issue... been battling her for a few years now... lol. If in fact it is... i'll be sending some love your way bud. Well done sir!!!
Bullshit. I've done this for 60 years and it's not just motorcycles it's everything and there is no way any mechanic worth anything would say nobody can fix anything
.. I have learned over the years that anything if you want to fix it can be fixed no matter what you have to do so.
But you're going to get it running I know stop with the diatribe I know you believe the lies about nobody can fix it but you
....😂 Do you know the word grandiosity ?
I agree. There is always a way
@@XJonAye Joe just has enough money that's all there is to it he has some skills but he's still a juvenile
There's always a way if you've got the time, will, and money. Not many have all three.
@@RonaldDaub-v9ypffffttt had their hateraid this am huh
If a mechanic says he is stumped and can’t get it to run….. then he is NOT a mechanic.
Yeah, he should KNOW why it wont run, and cant get the parts to fix it
Well,son. This here is just No Mechanic !!
you've given me hope to fix my hondra cfr150 dirt bike. I may not have all the tools, but it I can Identify the problem. I will save a bunch of cash. Very good video!!! My problem is the kick start wont kick. I will update as I look for the problem. Thanks!!
I now believe my education is complete. I have watched a ton of your videos and the stator and the coil were the last parts I haven't seen need to be replaced to get the project running. These videos teach without ever having to have the misfortune to be in a bad spot. I knew it was an electrical problem pretty fast but once it wasn't the CDI I couldn't figure it out. The spark fooled me as well and I was lost. Joe always gets the job done.
So it's a 91? With a motor from a 95? And plastics from a 88-89? What a mess
A very nice running and peppy mess though.

Wow, nice job. I hope you contact the owner. And told him the easy fixed you this Problem. Yes, it took hours, but at least you solved the problemi. Can't wait to see the next video. How you're going to fix your other one I do like 2 strokes. I used to ride 2 strokes back in the 70s and 80s.
My Dad told me 99% of problems with bikes or cars are caused by electrical issues. half way through this vid I'm screaming swap the coil out .Don't worry about fueling and carbs and that shit. I had a Kawasaki Z200 in the 80's and a Triumph Scrambler new in 2006 both bikes had coil problems, and both bikes behaved differently. Great vid tough very interesting, keep up the great work 👍
I thought it was hairline crack or pin hole in the float. I'm glad you checked it..your awesome mechanic
I had one these went thoug spark plugs like crazy. Loved it.
Ran my own shop and I had known good S.P. coils, stators, and other parts sitting on a diagnostic shelf for most popular dirt bikes, sport bikes just to do the" check the easy stuff first" kind of parts swaps. Saved hours of diagnostics and lots of $$ for my clients. Simple is not always simple. Time is $$. Good job in any case. Solved the problem which is what counts in the end!
I'm working on a recently rebuilt CR80. Ran great about 10 hours customer said. Now it dies out when it gets warmed up. Smokes like crazy. The crank seal on the oil side is the problem 😊. If it burns gas I can fix it is my motto. 😊❤
Aside from visual inspection of that which is visible and making sure connections are getting good contact, always work from the spark plug back, swapping simplest parts first. Woulda saved you a lot of time in this one. But as long as you enjoy the process...! Plus, now you know that the case seal area has been worked for some reason. When you pulled that, I thought there's no way that is ok. But it sure seems ok now! Excellent work, chap!
Reminds me of my childhood, dad got us kids into dirt bikes at young ages, had our own track that developed over time wi many riders contributing to the natural buildup of banked corners and jumps. I had a great upbringing, constantly challenged and inspired by dad....
That bike reminded me of an XR 500 I had back in the 80's. Loved the video.
I had a CR250 as my 1st road bike when i was young. Had it on a Q plate in the UK, was an absolute monster and still regret getting rid of it to this day.
Never ridden a motorsickle in my life and im hooked,great job pal.
The cr 500 had similar problems back in the day we found valve issues and back feed to the coil. Ps you are extremely brave try to 🦵 without boot on. We stole a coil from a Kawasaki 500 and it fixed the spark issue and had a vw machine shop due the valves. Good luck bro 😎
As soon as you started working on this bike I thought test / change the coil. I've owned a Honda that did the same thing !
i just got a 2018 polaris 570 crew because everyone and their brother and all their mechanics swore up and down it just needed a fuel regulator. After some short diagnostic and fuel pressure testing i determined the coil pack was junk and 100 dollars later it was fixed and running. 10k polaris for 4500 bucks. Cant beat it and i see stuff like that on marketplace literally everyday.
