Also met a guy at south of border training facility who just had same problem with same bike and he switched to race fuel mixture and all is good.

  went south with rider for the past week. Mixed 3 gallons race gas with 2 gallons 93 pump gas 32:1 bell ray h1r. He rode alot, lol, burned 20 gallons through practice bike. Problem solved. Stock yz250 will not last on pump gas if ridden aggressive.  Met another guy who had same problem and fixed same way.
bike is awesome, just run min 100 octane fuel.
thanks for replies
I hope this helps some others.

Hey, thanks. From what I read and hear from others, must have been fuel. Going to switch to cam2, and will update next week.
Thanks

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
