Yep!!

Looks like it was running lean to me.

What motor was this out of?

No, just on top end for too long on a road trip. The kid only knows one speed wide open.

Shane what kind of motor was this in???

I figured that was what you were going to fine.

Surely not a polaris!

Yep melted it to the jug. May have to only go 20 over.

Shane is this on your RZR?

Not good. That is one of two things. Ignition problem, or just plain over-revving for too long... You lead-foot!!!!!!

Maybe, on top end to long. He was trying to do about 15 mile loop in 10 min. And has never ridden it easy.
I was surprised it has happen sooner.

Future racer no doubt!!!

Does it have a controller of any type Shane?? Reason I ask,after looking at the pic more, the side-don't look too scored, just the holed-top.
Of course the debris from the melted top will get between the wall and the piston and score it some, but usually high-rpm over-rev failures look wayyyyy worse than that.
Looks like the timing was, or did, advance too much.

I was owned...................... That's a 2-stroke piston.........

Ok you guys, are you to young to remember the two strokes? My first MC must have gone thru 12 pistons it would get to lean, Piston was $3 rings were $3 and spark plug .$65 sometimes I could clean te haluminum out of the plug and reuse. Turned out there was a leak in teh rotary valve house that allowed it to lean out but only occured after extended rides.

Pate, you are getting old buddy. That one had you puzzled. However, the left hand was moving while the right one came in for contact....

Actually, you are pretty damn good to catch it...... you the man.

I was looking too close to see the holes in the side..............and the number of rings.......BUT it still, two-smoke or not, has a problem...........

The problem was a child who thinks he is Bill Ballance for 4yrs. Than running it like a Indy Car too long. When its a midrange motor.

....still should not have happened.....engine has a problem.
