I know this subject has been going on for what seems like forever, but I haven't found the answer I'm looking for. Been reading through the posts on this subject (for days) and one guy says to go with the Hot Cams and the other says OEM YZ, and exhaust vs. intake. What I'm looking for is what really works for my bike, an 08 450. Has anyone tried the Wiseco cam? Thanks and sorry for a repeat question on this subject.
