Technical / Yz250 2011 problems
« on: December 22, 2011, 06:27:52 AM »
So here goes. Got tired of 4 stroke problems, got two 11yz250 . Use bellray h1r 32:1 with 93 octane non ethanol gas. One bike destroyed 2 pistons each within 10 hours. The other bike just broke a piston on the top, above the ring exhaust side.

Checked fuel cans and tanks yes oil mixed. Air boots super clean, filters changed after each ride.
any info would help. We have been heavily involved in mx for 11 years and this is a first.

Thanks
