Around what size is a stock 150cc motor jetted at? I have not changed my jet yet and have: A free flow air intake, an FMF exhaust (which has basically no restriction), a high angle cam (in-26.60mm ex-26.53mm), and a Progress Racing CDI (Not that that makes any difference with what I should jet at) With those mods I assume I only need to upjet a couple sizes but I just wanted to know what size I am starting with. I'm guessing its somewhere in high 's lol 100's but not sure.

The stock 24mm carbs come with a main jet anywhere from 103-107 get a 110 and a 112 and see which one the motor likes. The pilot jets on the 150s are usually a #35 which is fine so leave that alone. Alleyoop
