Raptor 660 jetting questions
Hello I have an 02 Raptor 660 and I dont know what jetting settings to use. It has a FMF Powercore 4 with a 1 1/8 in quiet core in it and a K&N air filter with the lid on. The guy before me jetted it for the FMF with no baffle/spark arrestor and GYT-R headers which I took off and replaced with stock headers. So my question is What size jets, clip position, screw turns should I use for my setup (Powercore 4 w/ quiet core and K&N w/ lid on)? Any help is appreciated.
