Cams

Recommended Posts

HEy does anyone out there have a cam in there bike because i got a 2004 RMZ250 and i think i'm going to put a pro circuit cam in there i mean its going to make a hell of difference i know that but how many ponies and where will it improve the most power and where will it be making all the power. i've seen videos of a yamaha YFZ450 with a cam vs. a stock YFZ450 and that one with the cam in there wheelies in like every gear & smokes the stock one i was just wondering if anyone has put one in there bike and how big of a difference does it make

Thank you

We use WMR cam setup with very good results. The bike pulls harder and more responsive all over. Call WMR and they will help get you headed in the right direction. Valve clearance with there cams are 4-6 on the intake with 4 making a little more bottom, but you need to keep a close eye on your clearance when running at 4. The ex. should be at 8. The valve clearance also controls at what degree you cam opens the valves.
