hey i have a yamaha qt50, it has the same engine as a pw50, you may have seen it in the photo galary titled as "this is what gets me the ladies". anyway it isnt quit runing rite because it has a diferent filter than stock and the exhaust leeks so it kinda needs to be rejeted... i have quite a few jets left over from my dynojet kit for my kfx400 lol. does anyone know if the jets would fit , kinda a stupid question i no, but it doesnt have to be perfect

Only way to find out is to take it out and look. But let me say this.. A jet being in the upper 100's would blow the engine of not even run .

well, we just put a 110 mainjet from my z400jet kit in, the stocker was like 40 r 50 lol. anyway its got some top end and it will ONLY run with no exaust and an open carb, i think ima need to get like a 90 would work fine
