Guest Deven Posted April 16, 2012 Posted April 16, 2012 cam info is a hot topic... Thanks for posting Quote
450Riot Posted April 26, 2012 Posted April 26, 2012 That's awesome. Saves a shopper a LOT of time. Thanks! We should get a sticky goin about what peoples mods are, how/where they ride, and what cam they use for it. Or add it to this?

Sum670x Posted May 9, 2012 Posted May 9, 2012 Anyone ever come across a crf450 pro circuit cam in our quad motors? Previous owner of my 05 put the cam and matching valves and springs in with it. I know it pulls pretty well but I've always wondered what the actual numbers would say. Quote
