Can I use a different head on my 426?

5 posts in this topic

I have a 01 yz426. I bought it as a project, and boy is it one. A valve dropped and hit the piston, thus ruining the piston and head.:thumbsup: My queston to the gods of the yz is can I use any other head on this bike, Like a 400-400wr-450-450wr? Oh ya can I use the lighting system off a wr on my yz426f? Thanks for the help.

heads from any 426 will directly fit. 400 heads fit with very minor modification. Your head is probably repairable for less than $400. Contact EDCo.

Thanks for the link, but the valve gashed the head pritty deep. It messed up the spark plug threads and it damaged where the valve actually seats.:thumbsup:

They can fix heads with holes hammered in them, valve seats broken in half, lifter bores ruined, cam bores scored, and about anything else you can imagine. It's worth talking to them.
