I picked up a new motor the other day that I want to install on the blaster and still run the factory carb for now. The motor has a +.4 mil crank and a trail port and ploish on it already. I also have a full pro circuit exhaust I will be putting on and a k&n air filter. My question is the stock main jet is a 220 and I am looking for a starting point on what jets I should get at the shop to start tunning. Any help at all would narrow my search.
Thanks
Dustin

a stock main is a 230, idk i would start maybe like a 300 main and work your way down, now sure about your pilot jet.

well with just the toomey setup they send you a 310, i wouldn't start any less than that, maybe even more, id rather be rich than lean to start, to much oil isn't going to hurt anything...
