Does anybody know what the valves are suppposed to be set at? I might have to call the dealer and get the book but I was wondering if anybody on here knew what it was supposed to be. Will they tell you at the dealer what it is supposed to be. It is time for me to do the break in work on it and I can do everything myself as long as I find out what the valves need to be set at. Thanks for any info

Off the top of my head I think,
Intake .10-.15mm
Exhaust .15-.20mm

You are correct for the Raptor. Being the same motor for the 4x4 I would bet it is the same.
