I have an 06 CRF450R and have a used 08 I will be sending in to CRF's Only to get some work done. My question is should I use it with the 08 cam holder and an 08 cam or should I use it with the 06 cam holder and an 06 cam or will it make any difference as long as I use the same year cam and cam holder? I will probably end up getting a stage 2 Hot Cam for what that's worth.
Thanks
