Dale: I had no idea that Yamaha made electric start 2 strokes back then. My mission then was to go to premix, strip everything non-essential, and install knobies. Now that we are into restoration your videos are most valuable. Thank You.
Nice relaxing video, there is just something nice about bring back old stuff that other people will throw out and making it work again, you could almost say you are being 'green' and saving the planet!
Nice of you to put the camera first and have to work around it some, in order to show the detail of installation. The engine was right there in our faces. Thanks. I had a new AT3 back then and would get laughed at for the electric start, but I could beat the other 125s in a drag race.
Yeah, that's the whole purpose so you folks can see.......sometimes I can't......that's the problem. Still trying to figure out this filming thing and learn about cameras. I know I thought it was weird to have electric start, now I think it's cool.
Finally did one of those clutch basket filings myself just this spring, on a newer Yamaha 1000cc sport bike. I think it had twice as many edges than that one there. What a PITA but cheaper $-wise than replacing. Was def harder aluminum, taking care to keep the file flat and take off only enough to get it flat as possible, time consuming. From what Ive seen, doesn't appear to be any wear limitations on those in service manuals so it's pretty much up to your judgment.
Nice work my friend, time consuming for sure, but the price of parts....if you can get them. (none available for the ones I work on) It make the riding experience much better when the clutch works right. Your right, no limitations that I know of.
Hiya Dale, So, I've rather not thought filing the clutch basket was a good idea. Here's my thinking: One would never get those all filed down equally. As such, the fiber clutch plate tabs that bear against them will no longer all engage evenly. This will over stress the ones that touch first, while the ones that don't touch won't carry any load. Thoughts?? Of course what's best is the aftermarket baskets that have steel over sleeves. They should make just those steel sleeves available to repair stock baskets! Thanks, Robert
I agree, no aftermarket/new parts available......you either file it so the clutch operates or run it without an operational clutch. I'm going to file. Been doing it for years, perfect no..... any issues, NO. Ride for another 50 years.
I've actually thought about jigging them up in the mill, and taking them all down perfectly/evenly. Not worth the time though... Nice video, as always!!
Doubt you could ever get anyone to pay you for your time to do that setup and machining. Especially when you can file it to work in 15 min. I do stuff like that for myself and for a video but would never do it for someone else and expect to get paid for it.
Thats exactly the problem i had with my RD! There is actually a picture and mention in Yamaha manual, so it must happen alot. I need to remember the pizza cutter for when i get a bike thats hard to find nuetral
Hi Dale, love your videos. I just got my ‘72 Yamaha at2 barn find running from watching your videos. Thank you. I got cocky and went around the block shifting with clutch not really disengaging. Started on a hill. Second time back hit the gas hard just after forcing shift into second and something just let go. No drive to sprocket at all. Opened up transmission and nothing obviously broken. Can the clutch just go like that?
Oh my, yeah you were probably a little ruff on her. These bikes are known for spinning second on the shaft. Yes there could be an issue with the clutch also. Just have to poke around and see what you discover. Be gentle, they are 50 years old.

I know my mission was the same, little did we know how really cool these little bikes were.
Nice relaxing video, there is just something nice about bring back old stuff that other people will throw out and making it work again, you could almost say you are being 'green' and saving the planet!
Being green.....I like that. My neighbors have never considered me green though......those smoky old two strokes. LOL

Another beautiful job Dale. Meticulous as always. Really enjoy watching you work.
Cheers, Peter.
Thanks again Peter!
Great video. Never knew Yamaha had an electric start model. Fascinating restoration! Thanks for sharing,
It is a little weird, but I think their sales were geared a lot toward women for the 125 Enduro.
Another one buttoned up Dale. It's like the Yamaha Comp Shop in your garage!
Best wishes, Dean.
Not really the Comp Shop, but I am having fun no matter what brand it is.... now isn't that what it's really about?
Great series!
Thank you, these are fun motors.
Thanks Dale , Great info . It always cracked me up that they put an electric start on a 125 .
Yeah, me too, I think it was billed as a girl's bike.....sort of..............
Nice work Dale! Hope you can get back to your own projects soon.
All projects are fun, but I do like working on my stuff too.
another great job dale a step nearer keep up the good work next video please

here and ready to go to work!
Awesome, glad to have you along Frank
29:30 The clutch springs don't need a whole lot of torque because in affect they have the biggest spring washer you could ever fit!
Roger that!
Good job brother.

If you're having trouble finding neutral that's the first thing to look at.

Great job Dale.
Is this an engine you are doing for some some one for a project of yours?
Hey Don, this one is for a customer in Canada. He snowbirds in Florida, so I expect to see him come retrieve it in October.
Thought there was ball that went in before the "pusher" goes in the clutch center??
Dale put the ball in from the 'other end'
Won't go in the other side, hole is too small on these bikes, must go in this way.
Thats on the bigger bikes, the pusher hole under the clutch pressure plate is too small to install the ball on these, must go in like in the video.
HaHa...should've watch the video first...I see the ball where it goes now😮
Roger that.
Here
Thanks buddy
Great video again, Dale..... thanks for posting.
Thanks Jeff
