YET- another cam question
Posted March 28, 2011 - 05:14 PM
went to get head assembled and builder stated i should look into some cams, as mine have some corrosion.
though this has been on a budget i really need to find a set of replacements. he told me to look into some 06yz cams... but from what i can tell...
04-08 wr/yz intake cams are same
03-05 exhaust cams are different
06-08 exhaust cams are different.
need some help here as i have a forum member willing to part with some 2008 YZ cams that are pristine.
i know im going to gain the auto decomp-
BUT are the exhaust cams just different to produce some more top end on the yz?
thanks all in advance

- If you use both the intake and exhaust cam from any 450, you will be unable to set the cam timing except by using a degree wheel because the 450 cam timing marks don't line up in the 426 head.
- The '08 YZ450 is a top end engine, and you would loose much of the smooth low end performance of your WR.
You are far better off buying a pair of Hot Cams made for the 426.

You asked a direct question about whether it would work or not and he stated facts. Not much more anyone can add to that. The info on changing to a YZ exhaust cam has been covered way too many times to repeat. Search, my friend, is your friend.
What else are you looking for? A good deal isn't a deal unless it's something you can use. So even though you found cams they may as well be Kawasaki ones as they are NOT a direct drop in replacement for your 426. Sorry!
