i just purchased a 04 crf cam to drop into my 450r.. do i need any modification to do this mod??? i have a full M4 exhaust with twin air filter and air box lid off. Any help would be nice!!!! Thanks guys, jason

Also what kinda power should i be looking at with this setup.?

I read alot about the crf cam in the bike and put one in mine and it rips! I also did the 13:1 piston and porting. I was 47 rwhp on the dyno.

I've got an 02 crf cam in mine. It seems to do the job just fine. Not sure if any differences in the years but mine was basically drop in.
