I’m taking my raptor to the shop tomorrow and my plan is to put in a know air intake/filter, stage 2 cams and an 11.1 piston. However I’ve been reading more and I hear of a lot of people putting in shocks with the stage 2 cams. Is that necessary?
To jump on this thread, I know you need new springs but if I do a stage 2, do I need new valves? I have a 2002. I "heard" the valves were too soft on the 01 but can't find anything online about 2002 and up. Also how will I know if I need to shorten the valve guide? I read that some bikes need the center intake one modified and some bikes don't.
In my opinion the OEM valves are fine, as long as they are not worn out. Keep in mind, its an older machine. Most of these have alot of time on them and since you have to have the head off anyway for the springs... when i did mine i had a local racecar shop cut my seats for the new valves. They only charged $55 for labor and i think the new valves were around $100 from partzilla. And i dont know about the valve guide
