I am from Greece and the Honda underbone style motorcycle (C 50 - C 90) used to be king. Pretty much the only European country that they are popular in. I had one as a teenager, impossible to kill despite the teenage shenanigans. Back in the day they were so ubiquitous people would (figuratively) throw them in ditches when they quit running. They were everywhere. Now we find ourselves in a situation where even the small cc motorcycles are emissioned and fuel injected, underbones are no longer made in Japan and people are full of nostalgia. An original Honda C90/C50 with papers will command 1500€, I have seen restorations that were asking 2500 and low mileage barn finds for even more. Whoever set the design parameters for this bike and engine was smart, the engineers that delivered were geniuses.
My current bike is a vintage BMW R100GS. Why? Because my first bike was a Honda 90 Trail. So old that it had leading link front forks and a second rear sprocket that bolted over the street one. Obviously, there was also a short piece of drive chain that had to be spliced into the street chain. This led to years of tuning and crashing a variety of motorcycles mostly in the dirt, sometimes with studs on a 1/2 mile ice oval. Please tell a 72-year-old diehard biker that you will treat this seminal motorcycle with all the love and respect it deserves. It has fueled dreams beyond imagination. Thanks for all you do.
Mustie, you are, without a doubt, my number one go to on RUclips. Great content, super easy to listen to, no stupid music, and not afraid of getting your hands dirty. Not like most ponce's that have to wear gloves. No gloves makes it easy to see what your hands are doing. Thank you for giving me great enjoyment. A kiwi bloke from NZ.
Evidently you’ve never done a lot of hard work that can maul your hands with one bad move. You do get used to working with gloves after a while. In my line of work leather gloves are the go to tool. 😦
my husband has been turning wrenches for over 30 years and never worn gloves....complaining about oil and cuts on your hands is so petty..it comes with the territory and for a "woman" who are "put off" by seeing a working mans hands ...umm better get rid of that gold digger....a real woman sees a working mans hands and thinks ..atleast he works and his hands bare proof of that...
@@tetedur377 you are absolutely full of it ...many many men don't wear gloves when turning wrenches..only the younger fellas who are worried about looking good wear gloves...the old school guys never have and still don't wear gloves...i've been around a garage my whole life and none of the men wear gloves...you speak like someone who hasn't been turning wrenches very long..i've got 54 years in a garage where the guys just do everything bare handed and never suffered anything more than a busted open knuckle
I was "helping" my old man work on his Oldsmobile circa 1970 something, he was under the front end. He was a tough man and not one to teach or explain stuff. "Hold this wrench here". He just needed that extra pair of hands like you needed. Anyway, the bolt he was wrenching' on gave way and the socket I was holding spun off. I watched in horror as it clanked through the frame and doinked him on the forehead. Expletives deleted... He never said anything else. I later found out from Mom; he told her he saw the look in my eye saying that's what you get for treating me like a piece of sh..t. Years later we worked on all kinds of car repairs, oil changes, he always asked me "what do you think? Looking me in the eye. Your channel is an intellectual challenge. Will it run? Not the point. Keep posting. Hearing your mind work through problems, keeps me guessing what might work and watching you figure it out, things I never would have thought about. Teaching all the way. learn by doing. God bless from West Texas.
Watching Kurtis on Cutting Edge Engineering when his wife/camera operator asked why he didn't ever use a hammer .I thought the same thing----Nice lady that IS a hammer until it's an adjustable wrench again.
I agree once again, great content and commentary. Mustie1 always makes you feel as if you're standing beside him. The man sure does persevere in a somewhat very relaxed approach. Thank you for inviting us along. (Ireland)
As other correspondents have mentioned, the Honda C90 and C110 were used by Australian and New Zealand mailman(known locally as Posties) as delivery bikes in suburban areas and now have cult status among university students with their cheap reliable and numerous numbers on the second hand market.
It's worth noting that the Postie bike version was slightly different to the ones sold in other areas, Auspost had a whole bunch of changes, such as the removal of the high/low range gearbox. I know one of the posties who got to trial the new model C110X for Auspost back in the day when they were looking at doing a switch over and he said they had multiple front wheel failures and brake wear issues on the trial and as such Auspost requested Honda deliver the new model with an upgraded front rim and some sort of change to the front brake to keep up with the abuse that these bikes cop. I assume the CT90 and CT110 underwent a similar process.
I am continually surprised by the seemingly endless number of fun/cute nicknames Aussies and Kiwis come up with for every day things. I'll add posties to my every growing list...
Recognised it straightaway as a postie bike. All it is missing are the giant fluorescent green saddle bags and rack bag. See plenty of auctioned-off bikes getting around as food delivery bikes. A much stronger/ better made prospect than the cheap new 50cc thow-away scooters.
My Dad and Mom bought me a Honda 90 back in 72 - 73! It was yellow. What killed that was the chain came off and balled up by the drive gear! Put a hole in the crankcase! Good bike for a 10 year old! Tried different puddies to plug the hole. Nothing worked back then! My first bike!
That was my brother's first motorcycle in 1973! It was a GREAT little bike that went places a person would shake their head in wonder. He kept it for many years and it never broke down. Great underrated motorcycle.
This was also my brothers first bike in the early 70s. we used to call them Honda crunchies. He caught me on it once with a Lambretta engine strapped to the rear carrier, the weight of it almost lifted the front wheel off the ground.
My first "real" motorcycle was a '75 CB200. I did have a 2-stroke moped before that. My dad bought my mother an '82 Honda Passport around the same time. Whenever my 200 would break down, I'd ride the hell outta mom's scooter. There's not a lot of difference between a Trail 90 and a Passport. And you're right, they're hard to kill.
Bought one of these brand new in the late 70’s for $385. I have owned about 10-12 motorcycles in my life and the trail 90 is the one I wish I had back.
Love the intro dragging the motorcycle across the floor stop grin for second and continuing to push the motorcycle. This reminds me of something that would happen on the Carol Burnett show in the 70’s in a skit with Tim Conway priceless.
Directly above the rag drain plug is the oil pump pick up. If it was hammered in too far, the pick up could be blocked stopping the oil getting to the pump so the crank seized
Top tip for protecting the con rod when working with the head/barrel off is to use a piece of radiator hose zip tied over the length. Tough as anything and little chance of any damage at all. If that was mine I'd get it running as is and ride it past Mr Rip-off at next years meet. Massive understatement on the work needed just to make the point. Nice video though I like your style a rare breath of common sense and a BS-free zone.
Rod kit, new piston & cylinder , rebuilt cylinder head . New clutch plates & springs. Gasket kit carburetor. It will run for decades to come. That is one of the best engines ever made.
I had a new S90 in 1967 that turned out to be actually made in 1965. It was my first bike capable of highway speed and I could get it over 90mph lying flat on the tank. It would wheelie nicely too. It had a gem of an engine and I loved it but I traded it in on a '68 Triumph TR6-R when I joined the army and could afford it. Thinking back though, the really cute girls liked the Honda better,
I Just enjoy it when you ask if one of us could lend a hand and hold something. You include us like we are there with you As I wish I could be one day to lend a hand and learn from the best.
Interesting to hear your historical hypotheses on the deterioration of the machine. Have learned a lot by watching and listening to your small engine and bigger engine assessments. Gotta go and figure out why a new lawn mower doesn't stay running. keep on sharing! Thanks!
I remember riding one of those from the 70's when i was a kid in the 90's. Well i have a high/low 110 honda motor sitting around. The next time im up that way ill swing by your shop and give it to you.
Honda made the C50, C70 and C90 and these referred to the displacement in cc’s. I had one in 1977. Later they called it the cub I think but they all had the auto clutch. I have a Haynes manual for it that I got for Xmas when I was 8. 46 years ago. My first engine!
You are definitely my MOST cherished channel on You Tube. Overall, no matter what you buy your You Tube audience is more than glad to pick up the tab so to speak. I did want to mention that this whole series of bikes is meg-problematic. When you rubbed the speedo on the one in your parts bin it has 1016 miles on it not 10k. You have actually motivated me to go pick up some yard sale items that I would really love to have like a John Deere sit down. Thanks for all you do. You're invinceable.
Thanks Mustie1, great time in the shop! Friend had a Susuki RV125 with a high and low transmission, we went everywhere with that as kids. Look forward to a project on yout 90's sometime.
Not often we see Mustie not progress but I think he knew that this was heading to the stash fairly early on. Wouldn't call it a fail but a potential parts stash and another video. Looking forward to see you revisit the Honda stash forty videos further on! Keep up the good work!
Used by the Australian postal service for outback use, quite rare in the UK.. Im only 74 but would love one... Thanks for the video young Darren..Ian = UK.
I had the 1966 S90 , paid $350 new I think . It got me around for 2 years in high school and loved it , when I went into the military I had to let it go , only 3500 miles on it , I still miss it :)
I rode CT110s for a year when I was a postman. Amazing bikes and given the insane loads and abuse they had dished out on them they were near impossible to destroy.
The C50 is 50cc, C90 is 90cc and they did a C70 which, you guessed it , is 70cc. Keep em coming M1, they are so nice to watch 👍Properly maintained those engines just ran and ran
I know you could fix it, it's just not worth fixing at that point. The crankshaft could also be toast, leaving you with almost no original parts. Still fun to watch the autopsy !!
Another thing. One of these days i would love to see you make some paddles and get the BEAVER going in the water. I can picture how you could do it. Weld home made paddles to the rim. That was such an awesome and difficult project that i would like to see go. That thing sticks in my mind.
$200, I thought you were going to say he said if you want this too take it....🙄. As usual patience and persistence wins the day. FYI Mustie1, like so many I enjoy your videos with snacks and a cold beverage. Therefore both hands are busy I can't be holding thing for you and I didn't move your tools 😂😂. Thanks for posting your latest project
Well Mustie, If nothing else, you have some parts to add to the collection for other projects. Might be worth a look to see if the crankshaft is ok and the rest if the bottom end and case. Good for the parts stash! Would like to see more on those other bikes... Good luck, sir.
Another entertaining video from Mustie1. Sometimes when something is a lost cause it is interesting to find out how it failed. In the early 70’s I was living in Idaho. A lot of these 90cc dual geared bikes were used by hunters to get way back in the wilderness and haul their game out. That oversized luggage rack came in handy. I was lucky enough to be able to buy one in 1972. It is one of the best small motorcycle ever made.
She's a real gem Mustie To clean up the poor bore try cutting the head off a long 3/8 bolt then hacksaw a slot in the end of the bolt the same width as your emery tape. Cut a foot of tape off the roll and fit it into the slot then fit the bolt to the drill. try that. spray it with kero or brake cleaner as you use it. Its rough but it works as well as anything else.
Awesome video as always. You ever put valve grinding compound on a Philips heads when it's slightly stripped. It fills the voids and lets the screwdriver bight.
I’ve rebuilt a ton of those. Easy to work on and will run forever once put back together. Also, eBay has all sorts of pieces and parts for those, new and used. Chinese cylinder and piston set and a used crank set etc could get you pretty far along.
@@1marcelfilms I'm kind of a fence sitter when it comes to restorations. Mustie's into "Rustorations" and that's OK, but there's something nice about having it look like it just came off the assembly line too.
I guess I do semi resto stuff. I want it to work well and look decent but not be perfect. I’ll use Chinese parts when I can’t get the original stuff. Lots of used stuff on eBay for those. This makes me want to buy another one. Put together an orange 72 for my sis 2 years ago.
Southeast Asia has a ton of parts for these as well. I see quite a few of these old singles with Lifan motors stuck in them. They supposedly bolt up with little effort, but the shift pattern is upside down. I can see the appeal of not having points to deal with, but it takes away something when they do that.
Great video Darren, I got a old xr 80 that i picked up about 5 years ago stuck solid. About time for me to get it going for the grandkids. I restored a xr75 about 20 years ago, so should be pretty similar. As always, love the channel!!!
In the late 1960's I had a Honda Trail 90 with the earlier version two rear sprockets that had to physically be changed in order to go from high to low gearing. It was likely a 1966 model? You mentioned that your yellow Trail 90cc upstairs has 10,000 miles. However, my recollection is that the white number on the far right is for tenths, meaning that your bike likely has 1016.7 miles rather than 10167 miles? Always enjoy watching your outstanding work.
SO.. I"m 25 minutes in. I've been in EXACTLY the same situation.. my brother had the Honda 200 3 wheeler.. anyway, we went through exactly the same ordeal, different since it was a 3 wheeler and the motor was a bit different, but we bored that cylinder and I'm not sure if he had it sleeved, I don't think so, put a weiss piston and rings in there, and we did get that bad boy back running again.. Love you Musite!! Thank you man
That model was my first bike, So much fun. The lowest gear was great for climbing anything. In high gear it was nice to cover all the trails between friends houses because we had no licenses as 13-14 years old kids.
Excellent video Mustie 1 :) also think also lost oil plug included engine oil plus O ring for Oil pressure got chew in motor to bottom cylinder bearing to and had long life too! But got as parts model as you said too and to bad hopefully got running and water screw up too ! Not first one tried fix up and always enjoy your ideas what happened to Mustie also did best could do! Also famous saying need repairs done leave to professional work at a excellent shop to help out! They give best results and get up running perfectly again!
the biggest difference between M1 and GG is GG easily sells parts and uses the money to buy relevant parts and usually has money in the good before selling the unit
Hey they can’t all be winners. Great video. Always something to learn. Pretty cool how the piston rings broke lose though. That’s a game changer. Thanks Mustie1.
Mustie1, I have been watching almost from the beginning and I have seen you pull off some amazing minor miracles. This one might take the cake as far as motors go. We will see. Of course I want to see you pull it off. Good luck!!!! pARTS MIGHT BE VALUABLE FOR THAT THING. PART IT OUT.
Ye gave er all she got capn. Nice work again. I am seeing original 1960s to 1980s Honda Xl, CT etc front fenders going for $200-$500 USD on ebay. Stay gold.
30 something years ago, I swapped a couple of outgrown kids' bikes for a C90 engine that had been rescued from a pond... I had to beat the piston out of the cylinder, as the rings had rusted to the bore, but not a single drop of water had made it to the bottom end. It was perfect! I grafted on my good top end, and it ran beautifully... Iirc, the pond bottom end had an N123 gear change which made it really quite old.. I'm sure my original broken engine was 1N23....
Always a great day when you wake up and sit down with your first cup of coffee and there's a new hour plus Mustie1 Darren video to watch and laugh at. I make sure I sip slowly as ya never know when he's gonna say a zinger and make ya snort laugh. Hot coffee nose volcanoes suck. One thing tho, on engines like that I always put some Marvel Mystery oil or Kroil (but that stuff is expensive) down the plug hole then let it sit over night.
21:22 Time for some whittling! 28:50 Not only were we standing on the No. 14 wrench, we also had the hammer. 😁 30:40 Then we hid the wrench on the bench (Hehehehe) 😉 Love hangin' out with Mustie1. Thanks Darren for all that you do.
I love that work recliner Mustie...wish my shop had room for one. I had high hopes for this engine. I think they're indestructible, unless you use a rag for an oil drain plug. Oh well. Fine job as usual
The trail series by honda were actually fantastic. They could take a lot of use and abuse. Everybody I knew abused the hell out of those things. I still have my Honda mini trail... Got to get it running.
This one was plagued by a hapless owner and some bad luck, probably both. Oil starvation by lack of maintenance was my first guess until Mustie's hypothesis, which I readily accepted. Just making the daily rounds with a wrench (to make sure there's no loose fasteners) and keeping on top of oil changes would've saved this bike. What a pity.
I recall a local gardening expert on a weekly radio show. He had all sorts of advice to people for improving the health of or saving their plants, but once in a while, he'd simply recommend that one "open the lid of the garbage can and give the poor thing a decent burial." . . . .
Hondas have a cult following! And they no longer make them, only gonna continue to become more rare and depending on condition valuable! That being said I would not give $200 but I’m also not a super fan!
Ed March would get thing working for like $14. 🤣 Nice to see another bike on the channel, I subbed years ago after watching you work your magic on a little Honda - been hooked ever since.
I used to have one of these as a teen and it was a real dog, always breaking down on me like never before!... I may have road it about five hours and then it would have another problem! My step brother and real older brother had Honda's and Kawasaki motorcycles that were really decent to ride, so that made up for the lost time!
Mustie1, I know it's been awhile since you did this video but I really hope you do a videos of pulling back together either the Honda 50 (Cub 50?) and/or the Trail 90. Old original Hondas are becoming real collectors items and I'd think that if you did some mild restoring, you could offer either right on your channel for some good cash. The Trail 90 looked to me like actual miles are just over 1K, not 10K. And this one is from that era when Honda finally eliminated the large trail sprocket in favor of a dual-range switch but had not yet gone 110cc (with newer front forks). I'm an old motorcyle buff as I'm sure are many of your viewers are, so videos of such resurrected types would be welcome! Thanks!
Just got turned on to your channel. Great stuff. I just missed going to that Rice-o-rama, got stuck working at the last minute on a Sunday. I tinker on a lot of old Honda bikes- that shake-n-break tool is genius. Never seen it before but I'm going to have to get myself one. Thanks!
My Beezers pistons were frozen in the cylinders after 20 years of sitting. Every day or 2 I would heat/soak/beat/repeat for 3 months. Then Brainstorm. I broke the porcelain out of 2 spark plugs, tapped for grease zerks, screwed it all together then 2 packed the cylinders and heads full of grease, bolted the head and gasket back together and started pumping each cylinder full of grease. After about 5 minutes of switching back and forth I heard some crunching, then Bam! 1 cylinder let go, so I just kept pumping the hard one and a minute later it let go. May be useful to all of you gearheads out there.
I picked up the Aermacchi for $150. The cylinder in the box doesn't match the lower end, and the crank was also siezed. I was able to get the crank moving, but likewise - the crank bearing is toast. The rest of the bike is decent. I was looking for a project & sure found one! There was another seller that tried selling us 3 CL/CB 350's for $200 that were also siezed and looked to have been left outside since the 80's - we walked away from that mess! Everything was rotted - even the aluminum. Still it was a blast at the event. Looking forward to going back next year! I might need another project...
Either way it still made for great viewing bro. A postie still delivers mail in my town here in NZ on one of these although I see on the news they use electric bikes for mail in some of the cities. Safe travels
that was a bit of bad luck mustie it does not happen that often mate you give it your best content great as allways i still like video mate keep on wrenching all the best

I love that fact that if feels like a two way conversation with us as you work!

Hands down one of the best intros I have seen. the little smile on his face made me giggle like a little kid.

Interesting to hear your historical hypotheses on the deterioration of the machine. Have learned a lot by watching and listening to your small engine and bigger engine assessments. Gotta go and figure out why a new lawn mower doesn't stay running. keep on sharing! Thanks!
I remember riding one of those from the 70's when i was a kid in the 90's. Well i have a high/low 110 honda motor sitting around. The next time im up that way ill swing by your shop and give it to you.
Honda made the C50, C70 and C90 and these referred to the displacement in cc’s. I had one in 1977. Later they called it the cub I think but they all had the auto clutch. I have a Haynes manual for it that I got for Xmas when I was 8. 46 years ago. My first engine!
Your sir are great to watch, I love the way you go step by step and explain every move..
I had that very model when my buddies and I were in our hill climbing phase of life. It was very reliable and very fun! Great viddy!
At first i thought "Not another mini bike video!" and then I saw the roll in !
You are definitely my MOST cherished channel on You Tube. Overall, no matter what you buy your You Tube audience is more than glad to pick up the tab so to speak. I did want to mention that this whole series of bikes is meg-problematic. When you rubbed the speedo on the one in your parts bin it has 1016 miles on it not 10k. You have actually motivated me to go pick up some yard sale items that I would really love to have like a John Deere sit down. Thanks for all you do. You're invinceable.
I finally got to sit down to watch Mr musty one video one of the best RUclipsrs on RUclips thank you Mr musty one have a wonderful Sunday
I wake up every Sunday morning to watch this showatch this show and I'm finally the 1st viewer, kind of a little game I play. pretty cool
Thanks Mustie1, great time in the shop! Friend had a Susuki RV125 with a high and low transmission, we went everywhere with that as kids. Look forward to a project on yout 90's sometime.
Not often we see Mustie not progress but I think he knew that this was heading to the stash fairly early on. Wouldn't call it a fail but a potential parts stash and another video. Looking forward to see you revisit the Honda stash forty videos further on! Keep up the good work!
Greetings from the UK, it would be a highlight of my life to own a CT90, very sought after here.
ps thank you for removing the reply from that fake channel offering "something for you ", love theyour videos.
Love your show, it’s always awesome. I think you made out well with the price. I would give you your money back for the rims and kill switch.
Used by the Australian postal service for outback use, quite rare in the UK.. Im only 74 but would love one... Thanks for the video young Darren..Ian = UK.
The dizzying array of different pullers you own always impresses a guy. Love the content!
I had the 1966 S90 , paid $350 new I think . It got me around for 2 years in high school and loved it , when I went into the military I had to let it go , only 3500 miles on it , I still miss it :)
I rode CT110s for a year when I was a postman. Amazing bikes and given the insane loads and abuse they had dished out on them they were near impossible to destroy.
The C50 is 50cc, C90 is 90cc and they did a C70 which, you guessed it , is 70cc. Keep em coming M1, they are so nice to watch 👍Properly maintained those engines just ran and ran
The bike was a fail, but the video was a HIT! Really enjoy watching you work. Thanks and hopefully you can use a few parts on another project.
Great video....my room mate and our pastor restore these bikes as a hobby. Lots to learn here. God bless.
I know you could fix it, it's just not worth fixing at that point. The crankshaft could also be toast, leaving you with almost no original parts. Still fun to watch the autopsy !!
Your engine autopsies are always informative.
Always look forward to Sunday morning with Mustie1!
Close cousin CT110 in Oz are legendary. Now in collectible market...selling for silly big $$. Had lots of fun on my "postie".
Another thing. One of these days i would love to see you make some paddles and get the BEAVER going in the water. I can picture how you could do it. Weld home made paddles to the rim. That was such an awesome and difficult project that i would like to see go. That thing sticks in my mind.
$200, I thought you were going to say he said if you want this too take it....🙄. As usual patience and persistence wins the day. FYI Mustie1, like so many I enjoy your videos with snacks and a cold beverage. Therefore both hands are busy I can't be holding thing for you and I didn't move your tools 😂😂. Thanks for posting your latest project
Finding out about that "shake 'n break" tool was worth the price of admission on this episode.
0:06 Love the look of, here we go again on your face. Made me chuckle.
The yellow 90 only has 1016 miles - not 10,000. Be nice to see you get that one complete!!
Not been 'round the clock' once? 11016 miles?
@@lloydpenfold486 No Lloyd, freeze frame at 56.13 clearly shows 01016.7 miles and it's too nice to be plus 100 grand.
Agreed! Found myself yelling at Mustie to look closer!. LOL
Well Mustie,
If nothing else, you have some parts to add to the collection for other projects. Might be worth a look to see if the crankshaft is ok and the rest if the bottom end and case. Good for the parts stash! Would like to see more on those other bikes...
Good luck, sir.
Another entertaining video from Mustie1. Sometimes when something is a lost cause it is interesting to find out how it failed. In the early 70’s I was living in Idaho. A lot of these 90cc dual geared bikes were used by hunters to get way back in the wilderness and haul their game out. That oversized luggage rack came in handy. I was lucky enough to be able to buy one in 1972. It is one of the best small motorcycle ever made.
She's a real gem Mustie To clean up the poor bore try cutting the head off a long 3/8 bolt then hacksaw a slot in the end of the bolt the same width as your emery tape. Cut a foot of tape off the roll and fit it into the slot then fit the bolt to the drill. try that. spray it with kero or brake cleaner as you use it. Its rough but it works as well as anything else.
Awesome video as always. You ever put valve grinding compound on a Philips heads when it's slightly stripped. It fills the voids and lets the screwdriver bight.
22:23 A ridge line you say? At least this one has more frame than the Honda Ridgeline. Great video Darren. Thx!
I watched several of your videos. I liked them so much I subscribed. Keep up the great work. I look forward in seeing more.
I’ve rebuilt a ton of those. Easy to work on and will run forever once put back together. Also, eBay has all sorts of pieces and parts for those, new and used. Chinese cylinder and piston set and a used crank set etc could get you pretty far along.
I prefer to see all the original parts cleaned up
@@1marcelfilms I'm kind of a fence sitter when it comes to restorations. Mustie's into "Rustorations" and that's OK, but there's something nice about having it look like it just came off the assembly line too.
I guess I do semi resto stuff. I want it to work well and look decent but not be perfect. I’ll use Chinese parts when I can’t get the original stuff. Lots of used stuff on eBay for those. This makes me want to buy another one. Put together an orange 72 for my sis 2 years ago.
@@Poppinwheeeeellllllieeeeez If you can't say anything constructive then don't say anything at all.👎
Southeast Asia has a ton of parts for these as well.
I see quite a few of these old singles with Lifan motors stuck in them. They supposedly bolt up with little effort, but the shift pattern is upside down. I can see the appeal of not having points to deal with, but it takes away something when they do that.
Great video Darren, I got a old xr 80 that i picked up about 5 years ago stuck solid. About time for me to get it going for the grandkids. I restored a xr75 about 20 years ago, so should be pretty similar. As always, love the channel!!!
Good Sunday Morning All
In the late 1960's I had a Honda Trail 90 with the earlier version two rear sprockets that had to physically be changed in order to go from high to low gearing. It was likely a 1966 model? You mentioned that your yellow Trail 90cc upstairs has 10,000 miles. However, my recollection is that the white number on the far right is for tenths, meaning that your bike likely has 1016.7 miles rather than 10167 miles? Always enjoy watching your outstanding work.
SO.. I"m 25 minutes in. I've been in EXACTLY the same situation.. my brother had the Honda 200 3 wheeler.. anyway, we went through exactly the same ordeal, different since it was a 3 wheeler and the motor was a bit different, but we bored that cylinder and I'm not sure if he had it sleeved, I don't think so, put a weiss piston and rings in there, and we did get that bad boy back running again.. Love you Musite!! Thank you man
That model was my first bike, So much fun. The lowest gear was great for climbing anything. In high gear it was nice to cover all the trails between friends houses because we had no licenses as 13-14 years old kids.
Excellent video Mustie 1 :) also think also lost oil plug included engine oil plus O ring for Oil pressure got chew in motor to bottom cylinder bearing to and had long life too! But got as parts model as you said too and to bad hopefully got running and water screw up too ! Not first one tried fix up and always enjoy your ideas what happened to Mustie also did best could do! Also famous saying need repairs done leave to professional work at a excellent shop to help out! They give best results and get up running perfectly again!
i can hardly believe my eyes! this is GoldGuy level technique! bravo M1!
the biggest difference between M1 and GG is GG easily sells parts and uses the money to buy relevant parts and usually has money in the good before selling the unit
Hey they can’t all be winners. Great video. Always something to learn. Pretty cool how the piston rings broke lose though. That’s a game changer. Thanks Mustie1.
Can't be good all the time .. I would've loved seeing you flying around on that out in the woods...lol...keep on keeping on buddy..
Mustie1, I have been watching almost from the beginning and I have seen you pull off some amazing minor miracles. This one might take the cake as far as motors go. We will see. Of course I want to see you pull it off. Good luck!!!! pARTS MIGHT BE VALUABLE FOR THAT THING. PART IT OUT.
Whether you realize it or not, you, my dear Mustie, are a National Treasure.
Ye gave er all she got capn. Nice work again.
I am seeing original 1960s to 1980s Honda Xl, CT etc front fenders going for $200-$500 USD on ebay.
Stay gold.
30 something years ago, I swapped a couple of outgrown kids' bikes for a C90 engine that had been rescued from a pond... I had to beat the piston out of the cylinder, as the rings had rusted to the bore, but not a single drop of water had made it to the bottom end. It was perfect! I grafted on my good top end, and it ran beautifully... Iirc, the pond bottom end had an N123 gear change which made it really quite old.. I'm sure my original broken engine was 1N23....
Always a great day when you wake up and sit down with your first cup of coffee and there's a new hour plus Mustie1 Darren video to watch and laugh at.
I make sure I sip slowly as ya never know when he's gonna say a zinger and make ya snort laugh.
Hot coffee nose volcanoes suck.
One thing tho, on engines like that I always put some Marvel Mystery oil or Kroil (but that stuff is expensive) down the plug hole then let it sit over night.
I was impressed at how easy the screws came out considering the shape of everything
21:22 Time for some whittling!
28:50 Not only were we standing on the No. 14 wrench, we also had the hammer. 😁
30:40 Then we hid the wrench on the bench (Hehehehe) 😉
Love hangin' out with Mustie1. Thanks Darren for all that you do.
That was good thank you for sharing and your time was really great never miss a video can't wait for next one
I love that work recliner Mustie...wish my shop had room for one. I had high hopes for this engine. I think they're indestructible, unless you use a rag for an oil drain plug. Oh well. Fine job as usual
The trail series by honda were actually fantastic. They could take a lot of use and abuse. Everybody I knew abused the hell out of those things. I still have my Honda mini trail... Got to get it running.
This one was plagued by a hapless owner and some bad luck, probably both. Oil starvation by lack of maintenance was my first guess until Mustie's hypothesis, which I readily accepted. Just making the daily rounds with a wrench (to make sure there's no loose fasteners) and keeping on top of oil changes would've saved this bike. What a pity.
Mini Trail: Treasure.
That shake-and-break works great on rotor screws.
Well, you’ve got your moneys worth of parts out of it if you don’t need them, somebody does. Thanks for sharing.
👊😎👍
I recall a local gardening expert on a weekly radio show. He had all sorts of advice to people for improving the health of or saving their plants, but once in a while, he'd simply recommend that one "open the lid of the garbage can and give the poor thing a decent burial." . . . .
Again, great fun watching and listening (except for the bang bang of rod on the case). You banger man. Thanks mustie. Always fascinating
He was asking $200 for that? I wonder if the seller was a used car salesman in a previous life.
I was thinking, "I'll throw it in to complete the deal" or "Here's $20 to take it off my hands"
He who sold you that has had your pants down!🤣🤣🤣
Hondas have a cult following! And they no longer make them, only gonna continue to become more rare and depending on condition valuable! That being said I would not give $200 but I’m also not a super fan!
0% inflation, Jack!
@@1pcfred 😉
Ed March would get thing working for like $14. 🤣
Nice to see another bike on the channel, I subbed years ago after watching you work your magic on a little Honda - been hooked ever since.
I agree Mustie1 that's a lot of work, when the bareing is burned up. Not worth the time, excellent video Mustie1 👍👍👍
I used to have one of these as a teen and it was a real dog, always breaking down on me like never before!... I may have road it about five hours and then it would have another problem! My step brother and real older brother had Honda's and Kawasaki motorcycles that were really decent to ride, so that made up for the lost time!
G;day from Australia love this channel keep up the great work horoo
Guess I have been single for too long, that honing made my blood take new routes. Great video, thanks.
Mustie1, I know it's been awhile since you did this video but I really hope you do a videos of pulling back together either the Honda 50 (Cub 50?) and/or the Trail 90. Old original Hondas are becoming real collectors items and I'd think that if you did some mild restoring, you could offer either right on your channel for some good cash.
The Trail 90 looked to me like actual miles are just over 1K, not 10K. And this one is from that era when Honda finally eliminated the large trail sprocket in favor of a dual-range switch but had not yet gone 110cc (with newer front forks).
I'm an old motorcyle buff as I'm sure are many of your viewers are, so videos of such resurrected types would be welcome! Thanks!
Just got turned on to your channel. Great stuff. I just missed going to that Rice-o-rama, got stuck working at the last minute on a Sunday. I tinker on a lot of old Honda bikes- that shake-n-break tool is genius. Never seen it before but I'm going to have to get myself one. Thanks!
My Beezers pistons were frozen in the cylinders after 20 years of sitting. Every day or 2 I would heat/soak/beat/repeat for 3 months. Then Brainstorm. I broke the porcelain out of 2 spark plugs, tapped for grease zerks, screwed it all together then 2 packed the cylinders and heads full of grease, bolted the head and gasket back together and started pumping each cylinder full of grease. After about 5 minutes of switching back and forth I heard some crunching, then Bam! 1 cylinder let go, so I just kept pumping the hard one and a minute later it let go. May be useful to all of you gearheads out there.
I picked up the Aermacchi for $150. The cylinder in the box doesn't match the lower end, and the crank was also siezed. I was able to get the crank moving, but likewise - the crank bearing is toast. The rest of the bike is decent. I was looking for a project & sure found one!
There was another seller that tried selling us 3 CL/CB 350's for $200 that were also siezed and looked to have been left outside since the 80's - we walked away from that mess! Everything was rotted - even the aluminum. Still it was a blast at the event. Looking forward to going back next year! I might need another project...
Either way it still made for great viewing bro. A postie still delivers mail in my town here in NZ on one of these although I see on the news they use electric bikes for mail in some of the cities. Safe travels
that was a bit of bad luck mustie it does not happen that often mate you give it your best content great as allways i still like video mate keep on wrenching all the best
Happy Sunday to you, Darren.
Very little meat left on that bone but a lot of fun watching you dig into it.
I am setting off to my yard to fix tools for next week at work and you put this up. No consideration for your public. I'll wait. Cheers
Good timing, I just took my Mini Trail for a deep dive into a “lake” of a puddle and did everything your not supposed to do from that point on….
