YZ 450f blown hwad gasket ?'s

7 posts in this topic

Hey my roomate just bought a 02 yz 450 and discovered that the head gasket is leaking. He wants to take it to the shop to get it fixed, but I told him that we could probably do it our selves with a little advise from thumper talk. Anyone got any steps we can fallow or just a little advise? Thanks.

Either it's a YZ450, or it's an '02, but it can't be both. 2000-02 were 426's, and '03 and up are 450's.

There are no "easy" steps. The procedure is in the manual. Got one?
