well my friend has a raptor with a full hmf exhaust, k&n pro-flo kit with no lid. and we need to know what the jetting should be. the main jets, pilots, the air/fuel mixture scew, everything. any help is appreciated.

thanks

 

i would try 165/170 and 170/175 mains depending on elevation.. and 3ed clips on needles with 25 Piolits 2.5 Turns out. This is a guidline you need to fine tune your perticular quad... after you re-jet check your plug after riding.

 

I recommend the dyno jet kit. I just installed the sparks exhaust along with this kit it was right the first time. it's a great kit for the $$$$.
