Im new to this site and new to my kfx 700.I just bought an 04 700. It has duel supertrapps ids2, twin air filter, and the guy I bought it from said it is jetted. Im not a mechanic but it seems to be running a little rich. it has some black sut crap that spits out from the end and around where it is clamped to the header pipe. Any suggestions would help. And one other thing I see everybody does the 12 hole air box mod , mine has a 15 hole mod each hole around 3/4" would this be ok.
