2001 WR250F W/ 06 Exaust Cam

Recommended Posts

There are two YZF auto decomp e-cams listed. They are the '03/'04, pn 5UL-12180-00-00, and the '05/'06, pn 5UL-12180-10-00. Both will bolt directly into your WR and work beautifully (use the timing marks on the cam as if it were stock to your bike). I am not aware of what specific difference there is between them, but the lift, at least, is the same.

These cams will only provide a decent improvement in performance if you have changed from the as-issued WR exhaust system, though, at least by removing the secondary baffling.
