Why did my Piston and Rings Blow Up?
I've got Blown Piston dome and Rings on my 2021 KRX Side x Side with 1500 miles. It started smoking on the trail. I did a compression test. Left was ~150 psi, Right was only 60. It was time for the dealer and warranty coverage. They tore the top end down to find right piston missing most of the rings and piston dome/skirt that retains the rings.

Detonation? Doesn't look like I'm running lean........always use Premium 92 octane so it's not pinging.


Brain Trust thoughts?
