I think the book says 5,000. I change it about every 1000 and the filter at the same time. If you use it more on the road I'd say 2000-3000 miles.

Valve check is at 8000 miles, shim under bucket.

There is a sight window on the right, partly blocked by the rear brake pedal you may have to push it down to see it well.

Thanks doc they all sound super I'll either go with the 606s or mt21s.

I'd recommend Dunlop 606's which I have run the last 2 sets. They are the most aggressive street legal off road tires available. Ditto Pirelli MT21's. If you want the motocross tire that will do best on the street I run Dunlop 952's. That's what I have on my dualsported YZ400F
