    TY250 Flywheel

    Well after returning from our Thanksgiving celebration, my pictures had arrived from my phone to my laptop. I will post them with to see if any one knows by the diameter if not by looking at it, if it is the correct one for my 493 series TY250. I think the number on the outside face of the flywheel is F143-3073. I am not sure what that means or refers to. I have found nothing in my research mentioning those numbers. LaVern

    TY250 Flywheel

    Is there someplace that I might get the actual dimensions and perhaps even the weight? The one I have is 138.86mm, or 5.467" in diameter. I don't have an accurate scale to check the weight. I guess it really doesn't matter. It seems that as long as it works, it will do. It's just that my son has asked if it is possible to get the original, so I'm trying to verify what is the original. I am having problems getting the pictures from my phone to my computer so I can upload them here. I'll have to try later to down load them again. Thanks. LaVern

    TY250 Flywheel

    Italic Keyboard shortcut Ctrl+I I think the flywheel from the TY350 looks completely different according to the views from Yamaha OEM. feetupfun, Do you know if that number is stamped on the flywheel someplace? I haven't been able to see it yet. Perhaps when I get back out in the garage and get it off I can take a close look. Thanks Everyone. LaVern

    TY250 Flywheel

    b40rt, TY350? Did I miss type in the above post? The surgery I had was for cataracts, vision is still a bit blurry, so maybe I did, though I did not see where. If I did, I meant TY250 If not explain please. Thanks LaVern

    TY250 Flywheel

    Hello Everyone, I just posted my intro a few days ago, and in part of that intro I showed my current project, my son's TY250. My question regards the flywheel on the TYs. This TY is a 493-200127, which makes it a 1977 vintage. Were the flywheels made extra heavy for them, and are they distinguishable from other 250 Yamahas of that time frame? I ask this because somewhere around 1992 or 93 my son bought this bike. He rode it for a while until one day it quit on him, no spark. My brother-in-law and I came to the conclusion that it was a problem with the points an no matter what we tried, could not remove the flywheel. I recall we messed up a wheel puller in the process. We ended up cutting the flywheel off. We acquired another flywheel from a 250 Yamaha at a motorcycle recycle yard. The owner of the yard said it was from a TY because it had the added ring for weight on the flywheel. It ran great for a few years until my son decided he wanted to ride Harley's, choppers and such and he parked the TY. Now I have it and I am in the process of restoring it for him. He tells me that he recalls the replacement flywheel was not the same as the original we cut off. I don't remember but I'm taking his word for it. So my question is, how can one know whether it is the right one? Obviously it worked for a few years until he parked it, so the question, is it the right one? I am laid up for a few days now from some minor surgery, so I know I won't be able to pull it off, but perhaps I can get a picture of it still on the engine. I did find the PT. # of the correct one from several different Yamaha OEM parts sites, #493-81350-11-00. They all had the same number but I haven't been able to find a number on the flywheel that looks like that. The pictures they show certainly do look like the right one with the added ring bolted on the outside, but my son says he remembers specifically that it did not run the same on low end. Anyway, in a few days I'll try to get if off or at least get pictures and dimensions. I'll try to put a picture up from Yamaha OEM. It shows the same type of ring bolted on as the one I have. Thanks for looking. LaVern
  7. timdog and Old Gezzer, thanks a bunch. My son wants to do a restore on the Yamaha. We'll have to see how that goes. LaVern
  8. TurboFurball, Thanks for the compliments I appreciate it. Intotrials,The tires make the TL a good "trail bike", especially for a 5' 4" 71 yr. old person like myself. Not a racer but a good trail bike. The suspension lacks what modern bikes have, but the reason we went with the trials bikes back in '75 was because the off road bikes at that time were getting taller and taller, making it harder to ride in the woods. My 2008 CRF150F is tall enough to be a problem for me if I get myself in a position where I have to put my feet down on a slope. Also since those pictures were taken, the original kick starter on the TL has broke and several attempts to have it welded have failed. Now there is a lever from a XL250 which is shorter making it harder for my knee to start it. The shorter straighter lever of the XL250 also won't clear the foot peg unless it is folded up out of the way. Thanks for looking and replying. LaVern
  9. Hello every one. I have been registered for a while now, but I never fully explored the Forum sections. Very nice to find manufacturer specific postings. I have several vintage trials bikes. A 1975 Suzuki RL250 which I purchased new. Also a 1975 Honda TL250 that I received from my cousin, who was the original owner of that. I didn't restore them but did "recondition" them. I presently also have a 2008 Honda CRF150F which I bought because my knee does not like the kick starter. At the present time I am working on restoring my son's 1977 Yamaha TY250. He wants to "restore" not just paint it and make it look pretty. I will be more than likely looking in here for help and information on my latest project. If I can figure it out, I will put up several pictures of my Suzuki and Honda after I reconditioned them. And the Yamaha as it is as I start to work on it. I know the TL doesn't have trials tires, and the Suzuki has a few dents in the tank plus the front fender is raised. Thanks for reading my post.
  10. Hi All, New here, this is my first time posting on here. I was searching for a Vintage Trials Forum and found you folks. Looking forward to participating. I am 66 years old, retired and in the process of.... I don't know if I would call it restoring, but I am cleaning up, painting, replacing tires, new decals etc. on my 1974 Suzuki RL250. I am the original and only owner of this bike. I never really rode trials but for the first 10 years I had this I did a lot of woods and trail riding, and as my family grew I sort of put it on the back burner for a while. When I wore out my first set of tires I replaced them with full blown knobbies, replaced the thin seat for something with more padding. I have started it every summer and rode it for a few hours every year. The engine never fails to start with a few kicks and is still giving me 123 -125 psi on a compression test. I've been working on this refreshing for a few months now. Hope to have it completed before summer ends. Well I just thought I'd say hi. LaVern
