Moto Vlog that screwed the bikes Idle: • Ripping it on our 80cc...
Hey what's up guys, recently my bro's bike "The black duck" has had a weird idle issue since we did that one Moto vlog. so we kept having it and decided to tackle it today. we fix the problem but its not set in stone so i bought new jets for it in the future. also guys i just got hooked up with a new editing software which is sick af. tell me what ya'll think of the editing with the new software down below. Appreciate your time.

My g, already on 122 subs now u just gotta get to 130 and your closer to 150. Let’s go
That’s the mission. So far I think I’m doing really well
Also GOD DAMN Ed boi with the fro
Yeah he’s growing it out too quick
These motors come with really inconsistent ignition timing so one motor might sound richer or leaner than another with the same carb. ur idle sounds really lean, but I agree it sounds good like that👍🏻
Yeah already got some
Jets for it
@@retro_2v993 So I’m Curious where did you get the exhaust from?
Spray carb cleaner on the intake manifold and/ or where the carb bolts on if it revs when you spray you have a vacuum leak
I’ll try that before I move on with something else
Exactly that i think air leak that why is iddle crazy maebe seal motor
@@retro_2v993 I’m pretty sure it’s condition to the carburetor that’s why it fell it I’ve had it happen to me so I put one layer of some type of tape and it stopped idling high
@@retro_2v993 love your guys video!!!
Awesome 💣💥🔥
What’s up
It’s idling way to high and it needs to be jetted and it will run better and if your carburetor was that loose it was probably getting to much air between the carburetor and motor
Thx man. I just bought jets for it so I’ll see what I can do to it next
Welcome bro
For a young bloke you know what your saying. That's good to hear. Siiiiiick
Appreciate it brother.
super sorry for any new views. this video has been chopped up and changed since release due to copyright issues. my bad this isn't how I normally edit nor drop a video.
I have been fight this issue for weeks and today discovered why:
I have a brand new pk80 and hasn't run right since i got it. Found seal behind magnet was bad, replaced it. But it will not go into "power band", it just dies or cuts out, etc. -
So i have been noticing oil pooling up around the bottom of the spark plug. Decided to pull the head after doing a plug chop and i noticed 2 white spots on the plug cone. The rest of the plug with normal'ish looking covered with cocoa brown oil, etc. hmmmm
Sure enough it has a crack right in the middle of the head that leads into the spark plug threads, etc. Really interesting part is that the piston was clean in 3 spots. 1 area by the intake side of the piston dome, and of course the same 2 more other spots that line up with the white spots on the plug!!!! This explains the crazy inability to "tune" these and they don't run right. Different carbs and jettings can be helpful, but won't fix it until you find the leak.
rest of the piston cocoa brown to black carbon build up. Brand new engine, funky stuff... now i gotta gets me a head.
Hope this helps anyone struggling with this issue. And this is common with the PK80 engines with that style of cast factory aluminum heads. Always do tear downs of these engines when new. Literally, cheack seals, true the moutning surfaces of the intake and exhaust, inspect seals, inspect for debri and so on.... the effort will pay off when trying to figure out why they don't run.... mine came with bad head and a wrongly wonky install seal.... can't wait to ride it, lol...
Second 🔥🔥🔥🔥
If ur not first then ur always second 😂 thx for the support
Throttle is adjusted to much so it's pulling higher than it should when at resting 🤦♂️
Just FYI, most outboard 2 stroke has the TC-W3 rating which is only for water cooled engines (cheaper but isn’t good for higher temps of air cooled motors). Make sure ur jug doesn’t say tc-w3, if it says JASO-FD or something it’s good
Ok ok thx for telling me becuz I was confused on the marine applications but this one says muti purpose as in all 2 stroke small engines. Or am I wrong?
@@retro_2v993 it might be ok I just thought that bc a lot of those big gallon jugs are intended for outboards/snowmobiles only. Usually the universal ones (non-tcw3) are a lot more expensive
Yeah ok thx
Make sure carb is tight and throttle cable has a rubber seal
Its air leaking in through carb intake check gaskets
I just put together a bbr 66/80. I had the same problem with the HP carb. Slapped on the NT and it feels like it has power now. Big difference for me.
When you buy one of those hp-carbs, you should buy a set of jets to go with it, great video, thanks for sharing.
i've started to see people saying that about these Hp carbs, maybe ill buy some and revisit? idk i already have a bigger and much more reliable carb.
Is You prees The clucht and is crazy iddle is air leak maebe the seal motor is Bad air leak some where
That could be why
Enjoy your videos alot brother I've got a chopper build in the works can't wait to get it started seems like the parts for these bikes are very expensive if you have any recommendations on where I could get parts for these choppers please let me know great work brother keep the videos coming g
yeah bro these parts have gotten pricy ever since i started and no not really, i have had to bite the bullet and buy at Ebay for the dumb prices, idk maybe try Facebook. i got a good deal there. with luck u can too
You didnt talk about decking the top of the float bowl. 99% of mystery chronic leaky catb is due to this.
check for crankcase leaks
i checked and no leak there.
It's lean You need bigger jet maebe #70 jet
Cool chopper brother
Thx bro. Aye btw I saw ur video on the reed valves and they were sick. I got one my self for mine
@@retro_2v993 o sweet. Good luck they r very temperamental but so fun. If u need help let me know I’ll do my best to help out
For setting carb You need start rich jet to down lean all rime start w rich to lean that way You know what jet is perfecto
All I run on all my builds is hp carb with #70 jet they work amazing. From my experience if you even have one little air leak you got big problems.
Ok but how come with the NT it had probs but with the Hp the idle was just fine on the same intake, exhaust and everything
@@retro_2v993 brake clean all intake pieces you will find a leak. It's not the easiest thing to fix at times. Just to be sure I copper silicone all my gaskets because sometimes the mating surface isn't 100 percent flat
@@Lowlinc ahhh got u thx for the info. U know being a RUclips doesn’t mean I’m instantly a teacher at this lol 😂 thx again
@@retro_2v993 no problem just trying to help. I like what your doing with the builds. I have run into many little issues along the way Wich have been sorted out one way or another. Biggest thing is air leaks.....they suck!! My current setup with hp carb I'm getting about 80kmh and has tons of power. Yes I am from the great north Canada
No medir la cantidad de aceite que le hechas a tu gasolina podrías dañar tu motor pues estarías hechando de menos y eso sería letal para tu motor pero si hechas de más podría no afectar pero si afecta en realidad pues no quema todo el aceite de más que le pusiste y hace carbonilla y eso sí puede perjudicar la integridad del cilindro pues los pedazos de carbón pueden rayar el cilindro suerte con tu choper así es que se aprende haciendolo uno mismo felicidades por su canal
After break in, I pulled the cap off the muffler.holly shit 💯 more power
mooopowa! baby!
I know what you'r idle problem is and it's not the carb . It's crank bearings and seals from running motor behond redline .if you read your book secont to last page 10 mph first 100 miles and no faster than 22.5 mph there after . 5000rpm redline half throttle run it wide open about 35 mph and 9000 rpm . You wore crank bearings out and crank seals are damaged . Pull mag cover off grab mag nut with plyers pull crank side to side if it rattles you ran the bearings out .

Yeah…. That’s the conclusion we are getting too rn 😅 we tried last night with video that never got uploaded and it still has the problem. Thx again brother, ur a real one ☝️ I appreciate ur advice and I’ll replace it soon. My brother did ride that bike like a wide open a lot 😅 thx again.
Try to adjust the float height and look for air leaks, it should run fine with stock jet...
its not the jets fault. its my own fault with the fuel mixture
ya fix it? was it an air leak around the intake??
Sounds good to
Thx bro
The angle of your engine/carb you could cut half the intake off and reattach I've done this on a build that came with that intake and it worked great. You want your carb as close to level as you can.
yeah that could have been part of it, but no its that we blew a crank seal
How's it running now? It looks like you're carburetor is tilted down to low🤔🤔
yeah the carb was to low but obviously that motor isnt on there anymore. next video incoming
you just need to move the float down for tuning typically
Changing from 44 tooth sprocket to 36 sprocket seems cool but should the chain be smaller than 415 to a 410?
I don’t think it needs to be smaller in width like that. I went to a smaller chain size due to if being what I had at the time
Try between 76 and 78 jet
If you’re bros bike is idling weird it’s most likely an air leak
Most likely. Imma tackle the issue soon
Ayeeee I got 2 stingray choppers too 😂
⚙️🚲⚙️👍🏼💯👊🏼
Yea engines will 4-stroke if they get too much oil it won't ignite right you got to mix it in a gas can first and make sure you would pay attention to what you're doing
yeah ik ik i just got it right recently
Metering rod up is rich down is lean .
What do you think about the one piece jug? Mine works great "fast"
Uhh well it’s like the Ford debate, “oh my truck has this much miles and nothing broke” meanwhile the other thinks it’s trash due to their experience with it. Me? I think the one piece jug is alright. Makes good power! But hard to work on when it comes to mods and inspecting the piston. So I don’t prefer it but I do realize it’s really good! But still I prefer the separate head and jug
Bought my YD 100 KIT new in May had nothing but problems. Added a G2 reed valve, and was hitting 48 and 50 mph. but was still having carb problems with idle, as long as i was wide open every where it ran like a boss couldn't use nothing but a number 4 spark plug she likes it hot. switched jets to a 78 and was a little better.Now i switched jugs to a LD single put on a new reed piston with the G2reed valve and bought the best aluminum racing head i could get, there's an option I never had with my one piece jug got rid of my stock exhaust bought a new viper exhaust and have now been clocked by the town clown cop at 66mph go figure lol like a boss. About
to add a boost bottle see if there's any difference keeping my fingers crossed. Gonna switch back to my 36 tooth sprocket, was trying out a 28 tooth witch is great but sucks ass on hills i live in ny state we have way to many hills here!!!!
Run amsoil dominator 2 stroke oil. it is the best of the best. way better than Pennzoil
Factory spark plug doesn’t work in a solid head it’s only for a jug with separate head you need a brigs and Stratton smaller plug the length of the plug delay’s the spark and the factory plug builds up carbon on the inside of the plug and that carbon falls out from inside the plug and that tiny peice of carbon can pre ignite slightly to early and make it rev like that because of the pre ignition it’s basically lightning fire when piston is at the very top or right before compression stroke it’s trying to push piston the opposite way because it is fireing slightly to early and carb keeps trying to ajust for it but it can’t i also use wires from a truck or car and cut them and screw them onto the cdi
What size are those plugs?
Push mower or weed eater spark plug
It will have like 3 or 4 less threads on it
thx
Make sure u use good oil and the rote ratio
yep i got it
Make sure your clutch inguages all the way. no load.
good point
The RPM need 1800 RPM You can Buy thacometer RPM for setting carb is costo only 20 bucks
Ok imma try and get one
Thx
Hp carbs need to be jetted properly until they run right
yeah i believe im jetted way to rich
These are put put bikes not race bikes regardless what you think on stock 44 tooth drive gear you should not exceed 20 mph for a long happy life . I use lucas oil and never blew a motor up yet.
Welp I guess I’ll go break the news to my bro. Video on this coming soon then bro. Thx for the advice
That’s zero fun 44mph all day on 44t ⚙️ in short bursts had 10k+ on my yd100 doin that but be careful. It’s to much fun.
@@JMB676 and that's why you destroy the.
@@charlesyates6687 lol what ever you say bud. I just think your extra cautious. Mine do great for me n I have a blast
Edit: and sorry but 10k on a single motor is a lot seems to do good for me idk many people that can say that
Wouldn't use anything but lucas and 93 fuel once in a while some octane boost
Im telling your crank seals are sucking air .
Have you used an o rig inside the carb intake?
nah, but i found a huge leak at the exhaust. so that might be it. thx tho
Idle should be at a lope like a harley not 2500 rpm .
You are a holy chicken just drive the thing
It needs a new plug
yeah im going to change it
Sounds like an air leak
Air leaking into the engine ...plus the bike is slow
yeah I figured and cool its a 66cc that's basically fucked
u need to drill the jet kid
or get a new one
No hating but Jesus loves you and I'm cuss words I like your videos but I don't like your cousin I would prescribe to channel but you need Jesus in your life I got one of them back and gives me problems all the time
Guy u have to mix it right or ur gna mess ur engine up. If ur gna go with w mix make sure u add the rite amount bud.the more u use the hotter the doark needs to be if u have to much oil it won't combust rite if it dnt that keans it won't push ur piston back amd ale it bounce back up
yeah i understand all of that.
A lot of people have issues running them if they do the recommended break in just go less oil more gas turn your carbs adjustment screw about 12 times from the start of the threads and then tighten down all the screws on the carb and the inlet to the carb from the engine if that doesn't work then remove the head check to make sure it has a smooth surface and if not sand it down to a mirror finish the best you can don't go to deep or you risk ruining the head also cleaning up the case if it has imperections and getting a new gasket for the head should help other than that i personally run high heat 2 stroke oil to protect from high rev engine damage and that results in me having to run things more lean also it doesn't make too much of a difference but if you use high melting point grease for your moving and connecting points your less likely to have wear as often on important parts just remember if you do take my advice put pedals back on cause you'll need to get it up to speed before attempting to start it cause the high temp oil doesn't appreciate low speed combustion till its hot. Tighten daily and run it 9 months of the year and that advice should get you to 6000 miles if your careful and not using it as a drag bike
