jetting

[Slapasack]

what size jets are people using with full exhaust with the rest of the motor being stock?

there is no correct answer for this...there are too many factors that affect it...elevation, temp, even the motor...you could have two "exact" motors come off the line back to back and they could require different jetting.

one thing we would need to know to get you in the ball park is if you have an aftermarket air filter or not?

ya i have a uni air filter
but i just thought if i could get an idea of what size jets i needed id buy a few of them instead of paying $70 for a jet kit when i dont need all of them

I am running a 42 pilot and 152 main. Yours would probably run good with a 40 pilot and 150 or 152 main
