    What to do with my carb?

    I have a yamaha blaster and I am wondering what I should do about a carburetor. Should I get a bigger carb for it or just jet my old one? Here is what I have done to it: FMF fatty exhaust, FMF powercore 2 silencer, UNI filter, power reeds, and bored .60 over with a Wiseco piston.

    with your mods you really dont need one if you were planning on doing some porting, big bore i would go to like 34mm carb, with what you have like i said the stock carb will be ok you could go to like a 28/30mm that would be good, a 34mm on a fairly stock motor like you have would be to big

    for the 240 i would do a 34mm carb but anything less than that or a good port job is just a waste
