yz cams in 2002 WR

Recommended Posts

I just bought some nice used 06 yz cams for my 02 wr250. The main motivation was the auto decompression. Should I use both cams or only the exhaust?

Also, would a 04 yz slip on fit my bike?

I would go ahead and use both. I haven't really heard of anyone mixing yz an wr cams together. Like swede said, the yz timing will give you better performance.

Cool both cams it is :thumbsup: I just wanted to make sure there wasn't some killer combo of wr/yz cams for low end or something.

I believe the cam profiles of a YZ and WR are identical, WR's are just retarded a tooth to take away the hit, timing a WR to YZ specs usually wakes them up.

Yes, you can use the slip-on exhaust, the mounting bolts will match right up 2001 to 2005 inclusive.
