Hello All,

 

I recently had the 2009 yz450f I just purchase (damn CL) topend grenade on me and I am curious as to what other year bikes/atv cylinder heads will fit.

 

2007-09 yz450, I assume the same is for the WR. How about the yzf quad? Trying to find a serviceable replacement that won't break the bank.

 

TIA,

Well, not exactly.  The carb model quad heads and the '07-'10 WR heads have provisions for air injection that have to be blocked off, and a couple of other details.  Best off staying with an '06--'09 YZ450F head. 

 

You should also contact Fast Heads or Engine Dynamics about reconstructing yours, no matter what it looks like.  You may be pleasantly surprised by what they can do.
