New Y426 head question???

3 posts in this topic

Hi there

i have to buy a new head for my 2002 YZ426. Long story reason why.

i will be using SS valves instead of Ti valves. i have bought new valves, springs etc already

In the Yamaha diagrams for the head, it doesnt show valve seats in the picture, But when you look at the valve diagrams it does

Would anybody know if the head i buy (OEM one) need new valve seats for it or would the new head have them already?

Ive heard its not a very easy job to do.

any replies would be greatly appreciated...
