jetting

How should i set up my jetting with fmf slip-on, k&n, and cut airbox lid?

Jetting depends too much on factors like altitude, there's no set jetting that'll work for everybody. Just buy a few bigger main jets and use trial and error.

i am at a normal altitude, in missouri, what is a general one i should try......

 

[madcow]

I forgot what the stock warrior main jet is, I think it's 145. Get a 147.5 and a 150. Or even better, check yourself, then buy 2 or 3 jets, each a size bigger, sizes go up in increments of 2.5.

so if it kinda backfires fire out when revving, then i need one bigger?

 

[madcow]

I'm not sure on that one, I'm not too good at the practical part of jetting, but I have the theory down.

Usually when it's so far off that it actually doesn't run right, backfiring and stuff, you need to go more than one size. If it's got stock jetting in it right now you probably need to step up to a 150 or 152
