Mustie, you are, without a doubt, my number one go to on TH-cam. 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
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 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.
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.
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)
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.
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.
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,
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!
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.
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
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 !!
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!
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.
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!
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!
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.
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.
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.
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.
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.
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 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.
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.
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!!!
$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
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.
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.
back in the 70s my best friend had one we drove that thing everywhere the high and low range really made it kind of unique and with the step thru frame it made it easier to drive in beach sand for better balance
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
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.
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.
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 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.
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 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 :)
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.
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.
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....
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!
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!
I heard a trick from a motorcycle museum mechanic that if you light a candle and place it under the block it will get the engine hot enough over some time to free it up instead of applying direct heat internally.
or even a small space heater. My grandpa had an old Toro walk behind with a 12 kawasaki engine on it and it was very hard to start - he had this small, square space heater (about 6" square) and he'd set it next to the block for a 'while' and then it would pull start like melted butter, lol.
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.
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!
My friend 48 years ago had one of these bikes I believe it was called a Honda 90 Semi Trail because it wasn't quite all trail bike. Nevertheless he used to ride it in the road position as you could get more speed. Of course he now owns vintage cars and a Harley but we loved that bike we rode it everywhere on vacant land. Japanese screwdriver haven't heard that one in quite a while.
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
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.
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
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.
Finally something too far gone for Mustie. I had a lot of friends with the Trail 70's and the Trail 90's back in the 70's when I was a kid. Those were well built, simple, fun little bikes.
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...
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.

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!
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.
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.
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.
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.
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.
Your sir are great to watch, I love the way you go step by step and explain every move..
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.
I love that fact that if feels like a two way conversation with us as you work!
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.
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!
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.
Hello from Kentucky. My favorite backyard mechanic on TH-cam. I really enjoy these videos. I’ve learned a ton from watching you. Thanks
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.
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!!!
Always look forward to Sunday morning with Mustie1!
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
Close cousin CT110 in Oz are legendary. Now in collectible market...selling for silly big $$. Had lots of fun on my "postie".
$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
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.
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.
At first i thought "Not another mini bike video!" and then I saw the roll in !
back in the 70s my best friend had one we drove that thing everywhere the high and low range really made it kind of unique and with the step thru frame it made it easier to drive in beach sand for better balance
The dizzying array of different pullers you own always impresses a guy. Love the content!
Your engine autopsies are always informative.
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
Very little meat left on that bone but a lot of fun watching you dig into it.
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.
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.
Well, you’ve got your moneys worth of parts out of it if you don’t need them, somebody does. Thanks for sharing.
👊😎👍
Finding out about that "shake 'n break" tool was worth the price of admission on this episode.
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.
I watched several of your videos. I liked them so much I subscribed. Keep up the great work. I look forward in seeing more.
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.
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.
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.
Happy Sunday everybody!
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 :)
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.
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.
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.
That shake-and-break works great on rotor screws.
0:06 Love the look of, here we go again on your face. Made me chuckle.
I finally got to sit down to watch Mr musty one video one of the best TH-camrs on TH-cam thank you Mr musty one have a wonderful Sunday
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....
I agree Mustie1 that's a lot of work, when the bareing is burned up. Not worth the time, excellent video Mustie1 👍👍👍
Great video....my room mate and our pastor restore these bikes as a hobby. Lots to learn here. God bless.
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 😉
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
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!
I heard a trick from a motorcycle museum mechanic that if you light a candle and place it under the block it will get the engine hot enough over some time to free it up instead of applying direct heat internally.
or even a small space heater. My grandpa had an old Toro walk behind with a 12 kawasaki engine on it and it was very hard to start - he had this small, square space heater (about 6" square) and he'd set it next to the block for a 'while' and then it would pull start like melted butter, lol.
Several kettles of boiling water over the cooling fins is another similar trick.
Back in the early 1970s, a friend had a 90. Different model but still, fond memories.
I bought a sonic cleaner after watching your channel! Best investment I’ve made in long time
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.
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!
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..
My friend 48 years ago had one of these bikes I believe it was called a Honda 90 Semi Trail because it wasn't quite all trail bike. Nevertheless he used to ride it in the road position as you could get more speed. Of course he now owns vintage cars and a Harley but we loved that bike we rode it everywhere on vacant land. Japanese screwdriver haven't heard that one in quite a while.
That opening 30 seconds was funnier than anything SNL has done since 1977
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 was good thank you for sharing and your time was really great never miss a video can't wait for next one
Whether you realize it or not, you, my dear Mustie, are a National Treasure.
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.
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
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.
Finally something too far gone for Mustie. I had a lot of friends with the Trail 70's and the Trail 90's back in the 70's when I was a kid. Those were well built, simple, fun little bikes.
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.
G;day from Australia love this channel keep up the great work horoo
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...
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.
I had a Honda CL70 when I was 14 and I believe it had 23,000 miles on it when I traded it in for a bigger motorcycle.
Wow, I had trail 90 back in the 70s.... love it
