WR 450 exhaust cam

I've been told that if I retard the exhaust cam by 1 tooth It will give me top end like a YZ. Can anybody confirm. Thanks for the help.

You can but it will throw the auto decompressor out of time.

I too have been told this. The process involves pressing the sprocket off of the cam and moving (re-timing) it so as not to run afoul of the decompressor lobe. I have not done mine yet but plan to do so after I get some breakin miles on it. :)

Personally, I would simply buy a YZF cam. IMO, repositioning the drive gear on the camshaft is too much scwering around!
