What are they?

2 posts in this topic

Hello all,I have been trying to find the valve clearances for a yz 426 2000 model,but after doing a thread search i am finding conflicting responses.

Some people say they are the same as the 01 model but others say they are different cause the 01 runs titainium valves.

So basicly at the moment i dont know if my bike should be set to this.

intake .10-.15

exhaust .20-.25

or this

Intake .15-.20

exhaust .25-.30

So which one is it people??????

Assuming that the head is still built as issued with stainless valves, the latter specs are correct:

Intake: .10-.15mm

Exhaust : .25-30mm

The '01 and up had Ti valves and used the tighter e valve clearance.
