    I have a new generic Mukuni VM22 carb I fitted to my TY175, I had the flange tuned to make it a round mount. Please help with jetting. I have tried to match the stock jetting, but I was wondering if anyone has installed a new 'pre-jetted' VM22 carb on their TY? What is the jet sizes you have used? Main, Pilot, needle jet and needle? I'm sure I need to replace the needle but don't want to buy several and they not work. Thanks,

    I need a new 1st oversize piston for a 320 Majesty engine. I believe that a DT360 was used originally, do pistons from any other models fit? Thanks

    I've got a couple of problems with the TY250 twinshock i'm rebuilding concerning the clutch basket. Well lack of availability really. the baskets on two of the engines have broken "fingers" and i need to source a good condition replacement. Now i've managed to get hold of a clutch basket for a TY250A but mine is a later TY250d i think. Has anybody tried to fit the A clutch to a later model? does it fit? are any mods needed to make it fit? Anybody got a couple of good clutch baskets if not? please pretty please

    Hi. Thanks for all the excellent TY info here. I used to ride a Bultaco in some of the local vintage events, but that was 20 years ago. I recently bought a pile of stuff that should yield one fairly complete 250, and tripped over a TY175 last week. One of them will be my new machine. I can't wait to go ride with all the other old guys. Personally, I'm hoping the 175 works out. Although they seem to be pretty popular in Europe, I don't know if i've ever seen another here in the states. It is a cool little machine. If I get a minute tomorrow, I'll post a couple photos. pretty solid bike, although there are a few odd things to sort. I may also have questions to p…

  16. There might be the possibility, of a trade deal coming up... I'll wind up with a TY175 .. 74' model I believe.. I like the looks of the twin shock classics, and those tiny little seats.. Give this fat man a place to rest. Ha. Just saw a picture of a TY with modern forks and a disk brake. Yes.. watching the classic trials videos on YouTube.. Those bikes are really neat.

  17. Anyone here know which front brake plate is used when converting the front brake on a TY250 mono to use an external arm as opposed to the enclosed one. I have one but it has been repaired and just need to sort a new plate. It is a Yamaha plate and has magnesium in raised letters on it. Thanks in advance.
