well i was told my 400 had a stage 2 hotcam and jetted for it. i just put on a slip on pipe and opened up the carb to see what jets are in it. its a 38 pilot and a 148 main. thats stock right? the bike seemed to run good before the pipe so now im thinking maybe it does not have the cam. Anyway to find out about the cam? so i guess my mods would be just a slip on and no lid on the airbox, but maybe a stage 2 cam. How should i jet it? this sucks

well i stuck in a 155 and turned the a/f screw out 2.5 times. i ran it down the street a couple times wide open to 4th and it ran great. no popping or anything.
