What is the best jet choice for a Yamaha TY175 carb. Same with the slide is there an improvement to be gained by changing from the standard carb settings which at the moment are as in the Haynes manual.

It is run on pre-mix, there is no oil pump.

    The main jet currently fitted is the std 240, have been recommended to use a 200 has anyone tried the 200?

    200 may be OK depending on altitude and if you do road riding or not. When my TY175 was 175cc and was being ridden only in trials sections, I found that a 185 main was just the ticket. If you do a bit of sustained high speed, I wouldn't go much leaner than a 220.
