I was going to remove the stock spark arrester with my air box lid, i have the pro-design intake and k&n air filter. Anyone have any idea where i should jet it as fair as the mains pilots needle or air screw?

 

I'm running white bro's r4 & fmf powerbomb header
flaps cut out and milled the inside air intake on lid
no holes cut it box lid
mains 155,160
pilots 27.5
air screws 21/2 turns out
sea level
this combo for me works perfect
all around even when I go up to 4000ft
she runs like a bat out of HELL!!!!

 

hey man did you buy it with the k&n? or did you just buy a reg. clamp on? and oh yeah where did you get it? havent seen it anywhere yet!

 

Hey I got my intake and filter as one, Moto Man was the name of the company i got it from they have a ad in the back of dirt wheels, but right off the top of my head i know that ctracing.com has them.
