I have a 2006 WR450. I ride mostly trails and fast fire roads. My bike is stock and everything is uncorked. I'm looking for some overall performance. This is what I plan on doing. Hot Cams stage 1 exhaust cam, 13.5:1 Wiseco piston, and FMF powerbomb header with a Q4 exhaust. What do you think? Any other suggestions or comments would be great. Thanks in advance.
