I have a 04 raptor and i was going to get a pipe put on it and later a header pipe. The guy at the shop ask me what stage jet kit do i want 1,2, or 3 this kit comes with a filter. This is about all i'm going to do to the motor which stage should i pick?

yamaha you suck

 

I would make sure you get the GYTR jet kit. Dont get the dyno jet. It seems like every one has trouble with the dyno jet with a raptor. They cant seem to get it to run quite right.
