2002 YZ426f Exhaust Cam

I have one of these exhaust cams laying around and would love to put it in my 05 WR450. Is the '02 426 cam the same as the newer YZ450 cam? If not what cam should I look for for my WR?

I do not think the 02 YZ cam will work. It doesn't have the right decompression lobe for the E Start on our WR's. Get the 05 YZ ex cam (OEM) from TT about $90. I hope to have mine running with the YZ cam tomorrow.

If you really want a beast, the 03 cam is what you want. Weren't the YZ 450fs their wildest in 03?

As already stated the 02 didn't have an auto decompression cam so if you install it your magic e-button won't work. :applause:
