- In this video I install the top end, install the engine in the frame, anneal a copper head gasket, start up and test ride. All is well, the instruments work the lights work, the engine sounds great, shifts nice. Seems all we need to deal with is the broken loose heat shield on the muffler, is rattling bad. Think a new set of insulators will help with that issue.

He knows a thing or two about two strokes, that fellow in Montana. Started first kick and sounds as sharp as a razor.
Great job Dale, he's a lucky owner.
Best wishes, Dean.
You are too kind my friend. Really enjoy these bikes, working on them and riding them. Fun and simple.
It’s great watching someone who really knows what they are doing working on such a lovely old bike. Inspirational! 😀👍
Thanks, James, for the kind words my friend.
I recently picked up a ct1 175. Never have I ever worked on motorcycles before so kinda scared but this video makes me feel better
You will enjoy the CT1 Yamaha, they are great bikes, glad this video has been of some help.
Dale, you make it look so easy. I wish I had your talent. Good job.
Thanks Jeff, your too kind. I'm sure you can do whatever you set your mind to. I have enjoyed these all my life. Still learning new stuff every time, I mess with one.
anealing copper and aluminium re- aliens the molecules that get twisted from work harding. learned this when making copper bracelets.
It sure does work slick.
Good job Dale
I am continually learning from you.
I enjoy all your videos.
I have 4 of those 175 takes me back when I was young simpler times.
Keep making this videos
Thanks Dale.
Thanks Mark, wow, four, these have to be my favorite. I really like the midsize bikes these days. I started on them in my youth, then decided the open class bikes were for me......today they scare me. Back to the more reasonable power level for me. Thanks for taking the time to watch the channel.
Thanks Dale. I really enjoyed that. What a great little bike. You've done a wonderful job on it!
Thanks again Peter, they are fun to ride and simple to work on. I enjoy them.
Great Work Dale, thanks so much for all the know-how shared with the Yamaha 175 project. I'm sure I speak for all the guys when saying it was very enjoyable and educational to watch. I hope the owner has a blast riding it.
Thanks Jeff, your so welcome, I sure appreciate your support. The man that owns it is several years older than me, and I think he is ready to relive some youthful times. I know every time I swing a leg over one, it is a thrill again.
Thank you so much for sharing your videos. I’m in the process of tinkering away at a ‘74 DT175 restoration (last 6 years😂) and was curious what the transmission looked like inside. Having watched your video, I’m more than confident I have the skills to open it up and check things out. Thanks again……new subscriber.
Hey Jef, I have never had a 74 apart, but from what I understand they are still pretty close to the 69 through 73 models, just a few minor differences. I have done several videos on those bikes. I am positive you have the skills necessary to repair whatever is a problem. Thanks for the subscription, I sure appreciate it.
Hey Dale, would have loved it if this series came out just a few months earlier as I had the same crank bearing issue with my first experience in moto repair on a CT3. I've learned so much from all your videos and they have been a huge help along the way. Was able to resurrect the bike and get the first start in 15 years out of her thanks to you. Thanks again, and keep up the good work!
Well thank you so much for the kind words. My hope is that folks can get some info from these videos to help them repair and keep these old machines on the road, so they can continue to be enjoyed. Thanks so much for hanging out in the shop with me.
They are a fun little bike, excellent trail bike.
Yes, they are, these days the mid-size bikes are my favorite.
What an awesome result after all your work. Fired right up and sounds amazing. Night and day from when you first got it. Another one saved!! Weather looks good out your way. Great day for a ride. The owner is most fortunate for your efforts. Well done!
Thanks Jim, I was really pleased. Had a lot of rain here, finally the sun is coming out and the mowers are humming. I heard from the owner yesterday and him and his wife are having a ball with it. He told me that his wife grabbed it Sunday and didn't return for an hour. Sounds like fun is being had.
Running great now, enjoy it
I think so too, makes me want to break mine out for a ride. But it has to quit raining.
Amazing work!
Thank you, appreciate you stopping by the channel.
frank here , just drove the slingshot down the strip here in Vegas,94 deg.
Hey Frank, you are a fearless man. Been raining here for over a week. Temps in the 50's
Good job brother.
Thanks Cain, appreciate you taking the time to watch.
great video dale u could tell first start up it woz happier keep up the good work
Yes sir, think it is a happy camper now. Thanks for watching Mark.
Would be cool to have one of them old dt's
Earle you should find one to play with. There are lots of them out there. It really is a good time messing with these old bikes.
Hey Dave, thanks so much for your vids I have watched a number of them so fare and I really appreciate you taking the time and making these vids. I have a couple of questions, not sure if you have time to answer them or not and I can appreciate you are probably a pretty busy person with your work and your channel, so concise answers would be understood. I have a 73 Yamaha RD350, just a bit of back ground info, the engine was rebuilt by the person I bought it from about 5 years ago and I have no reason to doubt his workmanship as his a Yamaha tech, I put about 1000 km's on the bike and I was jetting the bike (I bought a set of JL pipes) and in the process the left cylinder seized, it now only has 30 psi in it. When it first initially happened I thought I holed the piston and in discussed with myself I parked the bike and after having a serious medical episode the bike ended up sitting for about 5 years, I'm better now by the way :-) and this week I decided it was time to get the bike out and resolve the problem, (piston was not holed, just a lot of scaring on the cylinder walls) hence why I found your channel. Question1) The Right cylinder is good, barrel looks good everything is good, 150 PSI, the Left Cylinder, is 30 PSI, lots of Scaring, my assumption is to bore next size over and new piston and rings, the question is, can I get away with just only going to the next size over on just the bad cylinder or do they both have to be done. Next question is, while the bike sat on its kick stand for 5 years the crank case filled with injector oil, what would cause that? Thanks again for your vids they have helped a lot particularly the oil pump adjustment. Thanks Karl Squire.
Hi Karl, sorry to hear about your health issue, and I am really glad you have bounced back. Also, sorry to hear about the engine problem with you RD350. I really think you should think about doing a leak down check on your engine. It sounds like you may have an air leak, creating a lean condition on the side that stuck. My recommendation on boring is that you should be the same size on both cylinders. That being said, it will run fine with doing just one, probably not optimum though. I have heard of folks doing that on bikes and cars just to get by. If I were you, I would try to find a good cylinder for the bad side in a standard bore size. I think HVCcycle.com has reproduction cylinders but not positive. I think the issue with your oil filling the crankcase is the oil pump check valve is stuck open. It is located behind the inlet hose connection on your oil pump. There should be a spring and a ball behind the banjo fitting so be careful you don't lose them. Maybe a piece of dirt in the oil preventing the check ball from seating. Wish you luck with whatever you decide to do. I sure appreciate you spending time in the shop with me.
The engine sounds so crisp and responsive.
Hey Troy, these reed valve engines were so much more responsive than the old piston port engines. I have both and the reed engines are my fav.
Hey dale, you gotta her back together pretty quick. Good job as always
Hey Larry, yep got it going, I should have done the bearing replacement before, but was trying to save him some dough. But he is happy with it and him and his wife are enjoying riding it.
What Dale doesn’t know about 2 strokes isn’t worth knowing.
Dale if I may suggest you doing a video on a 4 stroke single of any type. It will broaden your viewers a fair bit I reckon.
You deserve a huge following on here.
Have a think about it at least, I know you have your specialty and do it better than anyone on here.
Hey thanks Sean, you know I have my feelers out for a 4 stroke and have for a long time. Missed a Honda CT90 a couple years back. They just don't come up in my area very often. Would really like a SL 100 or 125. I am sure you are right; it would broaden the viewers a bit. But for right now, its 2 strokes buddy.
Engine sounds tighter than a drum. Started up before your leg got halfway down!
Thanks Kevin, this is a nice old bike. Wish it were mine. I would take it a little further into the resto.
Brilliant video dale, could you enlighten me as to what you were doing at the 37 minute mark with the flywheel please, thankyou?
You probably missed the first video, about diagnosing bad crankshaft bearings. In the first video the bearings were so loose that pushing down on the flywheel when running killed the engine. Probably by opening the points too much. So, in this video after replacing the bearing I tried it again only with a block of wood instead of my bare hand and the engine would not die. Proving that loose bearings contribute to inconsistent firing of the magneto system. Causing misfiring and poor performance. Just a gee whiz thing, kind of fun though.
@@montana2strokeracer ah, ok, I have now watched the first video & see what you found & why you used the piece of wood in this video, You Sir are a Genious for showing us a another way to check for worn bearings, Im glad you still have your all your fingers :) Anyway, I have learned a lesson here, So thankyou for documenting your findings while you work on these beautiful old classic 2 strokes. I'm Subscribed & look forward to seeing many more for years to come. Keep up your good work & Take Care!. :)

I have a 1978 dt125 and i want to replace the piston. If it is a stock size and the bore isn't too damaged would it be safe to run a new stock piston? I've heard about going up in diameter .5mm
Hey conner, it's just not cost effective to do that. If its loose the only way to fix the wear in the cylinder is by boring to the next size and properly fitting the new piston. I know it costs more, but it will last you for years. I wouldn't recommend just putting in a piston.
Hi Dale! Yamaha cylinder jug 1974 DT175 DT 175 is compatible with the Bottom End of the CT1 engine? Thanks
Thank you, have never worked on the DT series small motors, I had heard that they were. The only thing I knew for sure was the 74 MX 125 head did work on the AT-1. I used one on my AT1MX project.
Merry Christmas and Happy New Year! Health and success in your projects.@@montana2strokeracer
Hi Dale, is the modern regular gasoline safe for vintage 2 stroke motorcycle engines? Mine is a 75’ DT400.
Hi there, yes and no, yes because what else are you going to use. No because two strokes don't like water, and ethanol mixed fuel is hydroscopic. Meaning it attracts water. What I use here is premium non ethanol fuel, some parts of the country it is not available, so you are stuck using pump fuel. I also mix 2 oz of Sta-bil with every 5 gallons. Now there are some videos on CZcams that shows how to remove the ethanol from your gas. I guess it works, never tried it. Some places you can buy Aviation fuel, that would be great if you can. When I was a youngster, we could get it for our cars at the airport. I don't see these days how that is possible because of the security around airports. Bottom line is do the best to use non ethanol fuel, if not available, just mix some Sta-bil with it, and have fun. Thanks for your comment and for watching the channel.
@@montana2strokeracer thank you so much!
Looking for a carb 1974 Yamaha dt 250 a .
Hi, I just don't know of any. Try bikeboneyard.com or eBay. They should be out there.
Okay hopefully this doesn't seem too long. I have a 1978 IT175. It needed a new piston so I had it bored 2 times over. Bought a new piston and new rings. Both the piston and the rings are NOS. And they are OEM yamaha. The top landing groove on the piston Will not fit one of the rings. I have measured everything the rings are the same but the grooves are a little bit different. One is ever so slightly wider than the other one. It's the top one that's narrower. So consequently one of the rings will not fit in the top groove. Has any one ever heard of this? I'm wondering if there are supposed to be 2 different types of rings for this piston. It almost seems like it would be a manufacturing defect from yamaha. Or that maybe the rings are supposed to be a little different.
Just ran into this with a ct3. (175)
The top NOS Yamaha ring is tapered or as Yamaha calls it the “keystone” ring.
Even the correct top ring only fits in the groove when installed on the piston, it won’t fit if you try to put it in the opposite way to check it.
Hope that makes sense!
Just like Cole says below, the Keystone ring will only fit when installed correctly on the piston. Make sure you look for the lettering on the ring near the gap, any lettering goes up.
Perfect responses. Problem solved. Thanks again!
What town are you in
Hi John, I'm in Great Falls Montana.
@@montana2strokeracer good job on the yamaha like to see people keeping these going I have a dt175 and a It175 and a 125 at1 all needing work from wa state
First
Awesome buddy
