6 posts in this topic

I got this 2011 wr 450 that's just been trail rode since new in 11 and never rejeted or opened up in any way just oil changes, any one have any hints about derestricting and rejeting maybe yz timing on the cams ?  the bike just don't run all that strong at the moment , is their a thread specific to a 2011 wr 450 being rode in the pacfic north west?

I think there are stickies above. Yours is the same as a 2007-2011. You could start with the Yamaha GYTR jet derestriction kit.

They run night and day different uncorked and properly jetted. The GYTR kit is well worth it's cheap price.
