After 5 years of watching this channel I finally saw a piece of equipment on the side of the road. I stopped, asked if I could take it, and then brought it home. As I was loading the 8.5hp Troy bilt pressure washer up I was informed by the previous owner that it probably needed a new starter. It had a pull start so I just smiled and nodded. When I got it home an applied all of the diagnostic knowledge I amassed watching mustie. Hit the spark plug with a wire wheel and put gas in it. It started on the second pull. I hooked up water and no leaks. I then pressure washed my patio. It’s a 400$ machine I got for free. Thanks Mustie.
I have a very similar story. Can't thank this man enough for sharing his knowledge.
Did you do the mustie1 laugh 😂😂
Just love the mustie1 channel
My Mustie moment was a Troybilt wood chipper that wouldn’t run. Paid $50 and cleaned out the carburetor like Mustie has shown us. Runs like a champ!
@@tmscheum that’s freaking awesome! A wood chipper would be really handy.
@@barrymcbride I don’t think I would do it justice
why do we love the Musti1, theres no hype, its just you and your best friend working in the shed like it use to be, rather then all this OMG running about and fakeness of other channels, we are not all 12 years old that need hype and show man ship, wish more was like this
I like how theres no women here. This is clearly a mens space channel.
As long as Mustie keeps wrenching I don't care what they do on those other channels. Take care of your neck Darren!
@@familyengineering5591 i checked my underware, defo at least one woman here that be me
You are the best teacher of mechanical systems on UA-cam. I enjoy every Sunday's lesson.
Welcome back. 👍 Missed you last week.
“I’m taking it easy ‘coz of my neck issues” **pops several wheelies at the end** 😂
Been watching for maybe ten years religiously every week. Best channel on UA-cam. Thanks Darren! 🎉🎉🎉
yes.. especially with that ISO-certified cloth helmet
I'm almost sure Vintco makes a top end and Crank kit for those 360's!
Thanks to Mustie I bought a 1974 Kawasaki 100cc G4TR agricultural bike for $100.00 at a garage sale the old girl ran but was a bucket of rust and badly maintained parts, I was lucky enough to get three spares bikes and was able to do it up to look almost like new with paint and new decals. Took 2 years on and off but so enjoyable just to go through the process and see the final outcome. In the end I got her licensed for the road and sold her for $1600.00 which was pretty much what I put into it all up. As I said it was the process of doing her up that the most enjoyable part. Cheers Mustie from down under.
I think I would've had to keep it 😅
My first motorcycle was a 1973 kawasaki MC90 Enduro. That was back in 1978. I was 10yrs old. Wow, what I would do to have it now.
Great video! Mustie is the best! My first bike was a Yamaha 360 enduro mine was a burnt orange color. My mother forbid me to have a motorcycle. I had to get some parts machined at the local implement dealership and saw it sitting in the back room with a blanket on it. Well I made a deal with the owner and I ended up taking it to my buddies house. Then one day a couple of weeks later my mother saw me riding it around town. When I got home she was very pissed. Told me I was grounded for a month. But my father got her calmed down and the next day I brought it home. I was fourteen at the time and the bike was a little big for me but I had a lot of fun!! Good times and good memories. Thanks mustie!!
My mom vetoed the motorcycle, too. "Not while I have anything to say about it."
Hi Mustie1- I just wanted to send you something small to put towards tools or a yard sale purchase or whatever.
I'm not a mechanic, but grew up on a farm and always enjoyed time spent with my Dad - I nicknamed him MacGyver as he is always tinkering with something or other - usually re - purposing something or other into something else.
I really enjoy your videos, particularly the variety of things that you work on.
Thank you very much for all you do, I really look forward to your new videos.
thats funny, i was given the same nickname name as well as Dr. Mopar lol
😊@@toxin911
Brings back memories of riding bikes around as kids, learning how to ride bikes in fields and tracks
A sigh of relief heard around the world.
lol agreed.
I second that
I hear you, but he can take a week off if he wants
Yea I was thinking Mustie went to see his folks in Florida.
Great seeing you get the 360 running. In 1974 I bought a 1973 Yamaha DT3 250 that's the color as your bike. 50 years later its still in my garage!
Never bore a cylinder before you possess the new piston. Always measure the new piston, then bore the cylinder for the specified clearance. That's the way I've always done it. I have 2 old boring bars and only use one of them. I have the unused one in storage. If I'm ever heading your way, I'll contact you so we can meet somewhere and I'll give it to you.
Welcome back Mustie fans. Hope you have a lovely Sunday. And thanks Darren, we appreciate all you do.
Looking forward to this one later today! 🥳
We understand you have a life
But really enjoy wrenching with a coffee on Sunday morning
@@perrymattes4285 I have a ton to do today, but the notification popped up while making coffee. Mustie Coffee is my favorite way to start the day.
Who the hell is this Darren Guy you speak of? LOL
I had a 250 Yamaha and watching you ride the 350 through the woods reminded me of when I rode mine on old logging railroad grades in northern Michigan 50 years ago. The good old days.
Awesome repair mate! Really loved seeing this old girl come back to life. Thanks for the journey.
Used to work for a bearing company years ago. Those small bearing assemblies were called needle bearings. The retainers that held the needle rollers were called cages.
Greetings from Sydney NSW: By any chance, was the packing called 'grease' ? No need to thank me mate.
When installing the cylinder on a two-stroke I usually compress the piston rings with a zip-tie, when it's slid down enough so that the rings are in, just snip it off. Have always worked well for me. Have only dealt with pretty smalls engines though, if that makes any difference...
Thanks for uploading, always educational and entertaining! Greetings from Sweden
Mustie1, I bought one of these in 1977 on base, transported it to San Angelo's, TX and then road it on the freeway to Tulsa, OK! With all my gear on full knobbys. A Beast! Sold it in Florida. Yes, pretty Torquey!
Vintage two stroke dirt bikes are always my favorite rebuilds/videos.
Always a great way to spend time learning and reminiscing on a Sunday.
Hi D. Really hope your neck feels better. It’s always great seeing you bring back old bikes and vehicles. Love the video. And as always, thanks for bringing us along!!😊😊😊 Darren.
I bought the same bike when I was 16 and loved it. It was in much better shape but I have enjoyed watching this bike get up and running. Thanks
My dad owned this bike long ago. He got stuck in a large pit with manzanita surrounding. He picked up the bike over his head several times and threw it to get out. He said by the time he got home he was the most weak and tired he had ever been. He was a very large man...a logger even. That is 275lbs dry.
I definitely appreciate the extra explanation. You quickly and concisely explain the “why” of your diagnostic hypothesis/process. Not spending too much time on it for those who know those “common sense” things, but explaining the complete reasoning to those new to the thought. I’m also impressed with the abundance of spare or usable substitute parts you have to replace needed damaged parts no matter what you’re working on. 😮😊. I guess, even more impressive is that you’re organized enough to be able to find them.
Hey Mustie1/Darren, just a quick thanks - Watching the video's a long time. Car broke down recently, from all the watching I was able to diagnose and fix the thing myself this time. Saved me a few hundred Euro's (it was the starter motor) and it was enjoyable too.
That zorst sound takes me straight back to '79 in Edinburgh, sliding on cobbled road right infront the local copshop..😂😂nice bike man.
The Enduro 🏍️ rips again. That’s all that matters and we enjoyed from afar.
As always thanks for sharing Darren 👍🇺🇸
Thanks Mustie1 for bringing back fond memories of me growing up, tinkering on dirt/trail bikes, the smell of 2stroke in the morning, riding with friends all day in the bush/beach/pine forrest.Great days. Cheers, Mate, from Australia.
I hope that neck problem gets better, not much fun working in pain. Take care, thanks for the video.
Love the ear protection, safety third 🤙🤣 Good morning Mustie, thanks again for your awesome content!!
My dad had this same bike in the same color. Man, does that sound bring back the memories. He's gone now, but seeing and hearing this reminds me of some great times riding with him on my little Yamaha 80. Something in my eye now.
Thanks again Darren your one of the few genuine utubers out there, no BS just interesting and informative videos.
im 55 retired and there is nothing more relaxing and therapeutic than working in my shop with my hands, not in a hurry to get anything done, other than to have fun with what im building. thanks for the video, i know the time they take to film and edit.
Hey bud, thanks for your weekly vids. Watching your stuff is usually a fun part of my Sunday morning. Especially love when you’re tinkering on the old air cooled dubs.
As a power sports tech the 75 on the old piston is 0.75 mm overbore. That is pretty standard for a first overbore. To get your correct size you need a 1.0 mm. This will allow you to hone it to size. As far as color difference on crank that is from them assembling crank at factory.
Wanted to say the same thing ... I got caught the same way Mustie did ... 40 years ago I was used to the number refering to Thousandths over bore, but metric bikes like yamaha were mm overbore.
Mentions neck injury, proceed to pull wheelies. Never change and thanks for the vid!
The 70's was always open.. I miss you.
Sunday afternoon a thousand girls wanting to go for a walk. I had a friend, I had the 175, we did races. We had fun. I want to go back in time😎😎
You are by far the best shop instructor on UA-cam. Thank you for your tutelage and dry humor. It needs lube. haha
After hearing hundreds of Mustie's "Nut Jokes" and "Lube Jokes" and "Getting a Large Rod into a Smaller Hole Jokes" I would hardly call it "Dry Humor". I laugh like hell though.
@@captnmike597 I'm glad that you got a laugh out of it.
I lived on a Yamaha enduro 175 when I was in high school many years ago. I loved that bike.
Dude, haven't heard "jug" since the 70's. Brings back some old memories of my Dad!
You mentioned being able to stop by local Yamaha dealer to buy a piston.
I was about 12 years old when I took a piston to the local Yamaha dealer.... for $15 I came home with new piston and rings.... was riding that afternoon. (Only had to mow 3 lawns to pay my Dad back)
Mustie, you are one brave man, running 360 without muffler!
Camera does not do justice, to the violence coming out of that exhaust port.
Yay! Good to see you back!
Hi musti 1, I remember those old 360s what beats they were. You know I don't know if you're ever even going to fix it right or not but if you're not you probably ought to sell it to somebody that will that's definitely a piece of history that needs to be saved completely. Other than that I thought you did a pretty bang-up job, which is why you're the original UA-camr. No sponsors no merch just plain old UA-cam❤
I hope you are ok i know you have been having problems and had to go to the dr for migraines i really miss your projects i wait every Sunday for them . Prayers brother
He dealing with another health issue right now. (Kidney stone)
A lot of what you are hearing is just how a Yamaha big bore single sounds. That "ringing" on deceleration is completely normal. (I had that exact bike I purchase brand new. Ran it for 27,000.0 miles before I rand the injection pump out of oil. New piston and rings from Yamaha and a bore job gave it 11,000.0 more miles and then I sold it.). Amazing motorcycle. Almost unstallable with the big bore and reed valve system.
I owned a Yamaha 360 just like this one, in the extra plug hole I installed a manual compression release it had a small lever on the handlebars . Mine new from the factory had a lower end that made a lot of noise also and as soon as you kicked it over the sound brought back so many memories.
I use a leather belt with small vise grips wrapted around around the piston with oil on the piston. Won' scuff piston and easily removed after ring is into the bore. Use smooth side of belt against piston. Has worked well for me for several years.
I'm glad you took the time to tighten your safety cap. Safety First!
My brother had a 175 back in the mid '70s. It was great for a kid my size.
Happy Sunday Mustie! Good to be wrenching with you....doing my best to lend a hand and not get in your way!
For once I can give you some advice. Get a block of wood with a slot in it to take the conrod. You can then sit the piston on this to hold it steady whilst doing the fiddly bits with the piston rings and starting the jug back over the piston/rings. Rebuilt lots of small 2 strokes, it is a pain!
Welcome back.Awesome as always.Thanks for sharing and taking us along
The sound alone brings back memories of road and trail rides of long gone days, thanks Darren!
Respect Darren, I must admit when I saw what you were doing I was really sceptical about how it woud run, that piston seems way too small and the single ring way too feeble, but it actually sounds pretty damn nice, and more importantly you seem to be having a blast on it.
As a motorcycle mechanic of many year, I have come to know that the piston skirt is what should be measured to fit the bore as the ring grooves are just a bit smaller.
Had an IT175 that had the same noise in the engine. It ran tor years with no trouble. Nos parts now carries misc parts for old motorcycles
You took me down memory lane! Especially the end of the video when you went for the ride! I had a 72 that we over bored, it had a fair deal of torque. Great vid!
Welcome back! I like these old bikes and it is fn to see them brought back to life even if it is just to ride it around the yard
This was another example of your knowledge and experience. A great two stroke tutorial. Kool
You brought back sounds of my youth with that bike. I could even smell the chain lube when you were spraying it! Thanks for the memories!
#1. After a 2 week wait. Welcome back!
Working on a 1972 DT2 250 at the moment. 3k miles, and in fantastic shape. As always, thanks for your videos!
Welcome back, Mustie. Thanks for the new video, my Sunday is complete! haha
This is why I like watching this channel Darren never gives up on a project and you always can learn a thing or too ❤👍
Mustie, just a note if no one else has chimed in - Yamaha uses a copper head gasket that can deform a little, what you were calling a shim really is the head gasket. The thickness of that gasket can be changed to set the clearance between the piston and the “squish” portion of the head. Too large, you lose compression. Too small, the piston might smack the head.
The 100cc Yamaha KT100 uses a very similar setup with a single-ring piston.
Edit - I see there is a full copper gasket in addition to the shim, missed that the first time. The shim must really be just that - a shim to adjust the squish.
I came here to make a similar comment. The ring did not appear to be a shim in the traditional sense, rather a filler to reduce the squish volume. Perhaps it was added to try to compensate for the failing compression.
In any case with a new piston with a different profile the original squish calculation would be completely useless.
The noise in the closing seconds of the video tells me that the bottom end is totally wrecked.
@@chrishartley1210No, the ring is the head gasket for the MX engine which uses a different piston.
@@jimtitt3571I looked back at the first part, the ring isn't where I thought it was and I assume it is the squish shim for the MX360.
I'm guessing that the replacement piston is from a DT360 which had only 30hp compared to the MX's 39 and the majority of the extra power would have come from the squish.
I'm concerned that leaving the shim out could have brought the piston closer to the head although the replacement head gasket could also be thicker. If the piston and head are closer then with all the play at the bottom end they could now be making contact at higher revs.
@@chrishartley1210 No quite, the MX version pistons didn't have ports in them and different cylinder porting which gave them more top-end power, the trail bikes used the ports in the piston to increase the torque at the expense of outright power. The downside of the ports in a cast piston was they had an unpleasant habit of dropping the bottom of the piston into the crank if you rode them hard. The MX engines also struggled a bit on cheapo pump gas as the compression ratio is considerably higher. You see this with kinda pitting on the exhaust side of the piston crown and excessive wear down the front (exhaust) side of the piston as it all starts to overheat from detonation. Measuring the deck height/ squish band is essential for strokers especially if the piston isn't original.
Re-jetting because it runs rich is also a mistake (apart from altitude etc), the stock pipe is double-walled (for sound reasons) with the internal layer being perforated, once this is clogged with carbon nothing works properly. Burning out helps but the only real solution is cut the pipe open and rip the junk out completely.
@@jimtitt3571 Interesting, that means that the piston that came out, which had ports, wasn't an MX piston. Need to look at the frame/engine prefix, if it begins with 446 it's a DT, if it begins with 365 it's an MX and someone has messed with it already.
Another great job! Always enjoy watching you work!
Cool looking and sounding bike.....so cool ya fixed it !
Hey Mustie lad, great to have you back, getting worried when you didn't show last Sunday. Hope you are OK now. Thanks for sharing and best regards from Ireland.
Realy nice fast funny bike and sound. Thanks for all videos Mustie. See forward to next project you find.
Glad you are back. Makes my day 😊
I can't believe you put that engine together with all that piston slap let alone the dodgy big end bearings! I doubt it will last long.
Yeah he knows that don't think he cares. He made the video and that's all that matters. Like he said it's almost impossible to find the parts for this bike. The crank's got a little bit of play. It might last a week or maybe a couple years who knows.
The show must go on. It's video time. I'm sure he'll have the jug bore another time or if it ruins the bore look for another. I hope it doesn't ruin the bore.
There is more than just that wrong with this video. This is an exercise in all the wrong things.
@@DaneSaysStuff I guess. Musty is a great old school mechanic and the thing does run. Just wish he had done it properly since these things get more and more rare every day.
@@Clearanceman2 Playing fast and loose with the word mechanic. Although that's been a trend on YT for a few years now. I agree it would have been nice to see everything done properly. That's why I came here to begin with. None of it was impossible, just slightly more difficult.
Well another excellent job by a fantastic mechanic. I enjoyed every minute of it. Your something else man.
I think it'll be a big mistake not to address the issues of the bottom end now.
Thanks for the shop time Mustie1! Great series!
Morning, everybody!
This old bike brings back memories of woods rides here in the mountains of East Tennessee with my riding buddies. Some of the best times of my life. Enjoyed the vid. Hope you have a blast with it!
Cool bike, good work. We used to knurl the piston skirts to reduce piston rock when things got loose. Also have lapped the head to the jug and eliminated the head gasket to increase compression ratio.
Yeah Mutsie1 back 🎉 happy had video this week. Missed u last week glad able iron things out
Great troubleshooting Mustie 😊
Just about to go to bed when, hey, Mustie1 video and on an ol' Yamaha. My first bike was a Yamaha. Great fix for few parts. Never doubted you for a minute. Almost 2am in New Zealand, so good night from me!
Glad your back Missed u last week... Really enjoyed the video keep up the amazing work 👍...
Love this channel so real down to earth learned a lot from him
Great video, she sounds Awesome. I hope you feel better. Thank you for posting 😀
Great work! Fun to watch too!
That is the one for you ! Do the bottom end and overbore the jug. Those are awesome bikes to ride and carry a very good resale value. Worth the investment. Maybe it will be delayed, but parts have to be out there - so many are being restored. You gotta do it. Awesome combo bike. Fun on the street. Has some balls. Hey - it’s always fun and informative to watch.
I had a 1975 Yamaha 400 enduro 2 stroke in the 80's.... it had wicked torque and was faster than i wanted to go down a trail.... nice bike Darren... thanks for the memories
I had a 360 and my brother had a 400 with electronic ignition and mine would smoke his all day.I even rebuilt it but it couldn't keep up with the 360.
Made for great viewing as always bro. Safe travels. Ken.
GLAD YOU'RE BACK!!!
Brings back memories of when I was a teen in the 70s riding dirt bike threw the old trails in the woods of NH. Great to see you back Mustie.😂
Once again, you drew new use out of something that looked destined for the smelter. Great job!!
Great video mustie , brought it back to life.
Another great video. Thanks for taking us along for the ride. That bike stand looked a little shaky with you up there doing the kick start!
Love watching you each week. Always amazed at your tallents. As a guy who craxhed his dirt bike and suffered a sever concussion I wish you would wear a helmet. I still have repercussions from my accident.
growing up in the midwest we had big sand piles that we called the "chat dump"..i imagine it's where they stored sand for salt sand mix for the snow..had a old big red that i wore slap out and then my uncle said ride this.."this" happened to be another honda but a 2 wheeler that i had to mount from a stump b/c i couldn't reach the ground..if memory serves me right it was a 500 and that thing was bad to the bone..man, the joys of being a kid in the 80s when times were more simple and the country was in a better place..keep doing what you do Darin
Missed you last week... I usually don't say anything on any channel.. to see me look at likes on comments..glad to see you!!
Another very good Video Mustie.. cheers from Australia
Very cool Mustie!
Growing up in Florida during the 60's and 70's we had Evel Knievel. Now we have "The Mighty Mustie" !!! What are some other titles he could have? Great Job Mustie bringing that Yamaha back for more adventures. Now you just need a ramp and a few barrels. Always fun.
So glad to see a video this week. Missed you last Sunday. Be well.
Awesome save sir and I think that you will have a great time on it thanks for sharing this with us six stars brother
Is any one else screaming helicoil at their scresn, any thing to avoid metric 😅 love your work.
Yes! Must not have any I guess
