could you guys help me out on what size jets a should be using...full hmf exhaust...k&n filter..no air box mods...elevation is around 715 ft....[img]i/expressions/face-icon-small-happy.gif[/img]

 

155/160, 25 Piolit Jets, and if you have stock needles ,richen the needles up one click each, oh , and 3 turns on air/fuel screew.

 

im on a 170/175, why dont you use yoru head and call HMF yourself and ask, or atleast ask who you bought it from.

why the hell would you put a pipe on a raptor and not remove the air box lid?

 

prolly because i do what i want, when i want, where i want, and how i want...i used my head and got an answer from here...

 

Are you referring to Mikuni Jets or DynoJets or what? I have a similar setup and I am running DynoJet needles on the 4th clip, with 148/150 DynoJet mains. Does this sound right or is it a bit lean? Any suggestions? Oh, I am also running 25 pilots, K&N Proflow with no lid. Thanks.
