Thank you thats a great help!

the jets are the same hex type, the fuel is drawn through the jet in the opposite direction to normal. If you don't know the TY 175 setup you probably won't be able to help, I am going to stick it on today as is and see what happens.

the carbs are the same 22mm and all the jets are the same apart from the main, 100 on 125 & 240 on the 175 but the 175 main jet is mounted outside the float bowl which I am sure affects the size required,

I have a ty175 and the carb is getting a bit worn, but I have a good ty125 carb, the main jet size is very different, can anyone tel me what size of main I should start with on the 125 carb when fitted to the 175. Cheers Tetly

Thanks for that I was considering lowering the gearing slightly so good to know thats a ridable option.

Thanks I will ride it for a bit and see how it go's.

Hi I am new to trials but I am going to trial a TY175, it has standard gearing [13-51] is this a good setup or should I change it?
