Ok so I just got done putting a cam in my 87 Warrior. I have a K&N, White brothers pipe, and now a mid-to-topend cam. My question is what main jet to run. Right now I have a 150 in it but don't know if I should bump it up some more or not. What do you guys think?

For what you have done, I would increase the main jet size by at least 3 and see how it runs.

What increments to jets step up in?
145-150-155-160???
or
145-146-147-148???

145, 148, 150, 152, 155, 158, 160 . . . .

If you're running a .150, try a .158. If it sputters at top rpms, step back down one size and try again.

Jets are cheap. Why, they're only $4 at Clean Genes even!
