I'm intrigued with the black shields/guards inboard of the footpegs The number plate is cut from a plastic cat litter container from wall mart lol.The yellow is a good match and already had the curved edges. 2 Quote Link to comment Share on other sites More sharing options...

scot taco Posted November 12, 2019 Report Share Posted November 12, 2019 (edited) I have posted a pic of this before but thought I would add another just because I love this old war horse. We went riding this last Saturday which was probably the last one for the year. It was sunny and 45 degrees F. Today it,s 22 with snow and 35 mph wind gust making 2 ft tall snow drifts.

Sheepdog Posted December 30, 2019 Report Share Posted December 30, 2019 Hello. I just picked up this bike today. It has a lot of cool stuff I know nothing about. Looks like a Mikuni carb and reed spacer, 520 chain conversion, Betor shocks, oil injection removed, that is what I can see for now. I am sure I will have lots of dumb questions but old guys with motorcycles are pretty cool. Looking forward to going through this bike and getting it straight. Cheers, Eric 1 Quote Link to comment Share on other sites More sharing options...
jon v8 Posted December 30, 2019 Report Share Posted December 30, 2019 Nice bike,looks like Ethanol has buggered all the plastic pipes - It will do the same to the fuel tank too.Looks like a Sammy Miller tank / seat unit like I had on my last TY250,the Ethanol wrecked it... The footpegs have been moved back, they are now where everyone seems to have them. I don't know anything about the early 250 motors, FeetupFun is the man who really knows about them.All I would say is that the Ty250 is just about the best twinshock trials bike you will get in most respects.Mick Andrews and Yamaha got their sums right back in the day,and there is plenty of support and knowledge around to make them even better now. 1 Quote Link to comment Share on other sites More sharing options...
Sheepdog Posted December 30, 2019 Report Share Posted December 30, 2019 Jon, Thanks. Fuel lines are easy. Luckily, it looks like the tank was sealed at some time. It has been sitting for at least seven years and all of the sealer is starting to flake off. I am going to clean it out completely and reseal it. It will hold fuel, but no since in trying to run it with that mess in there. Thanks for the footpeg help. I thought they had been moved but was not sure.

feetupfun Posted December 31, 2019 Report Share Posted December 31, 2019 Yours is an early A model TY250. It will probably have a engine number prefix 434 and frame number prefix 434. There is no reed spacer on your bike. The alloy plate you can see the edge of is part of the reed cage. That carby is an aftermarket Mikuni. Easy to tell by the large spigot that the fuel hose goes onto and the idle air screw is on the wrong side. The original carby on the A model TY250 is a TK brand. The TK carby is good until it wears then not worth keeping because the wearing parts are expensive/unobtainable. Later model TY250s came with a Yamaha-Mikuni carby that was unique to the TY250. The B model TY250 Yamaha-Mikuni is different to the C,D,E models TY250 Yamaha-Mikuni. The important parts are not interchangable between the off-the-shelf VM26 Mikuni and either of the VM26 Yamaha-Mikuni carbies. Your carby may well work well. If it does work well and is 26mm, please share the jetting specs because I've never been able to get the one I bought to work well on a TY250 motor. 3 Quote Link to comment Share on other sites More sharing options...
