^ my story is just like his. Between myself and my buddy staying with me, we have 7000 miles across 3 pros and no issues/rebuilds. Not like that is a ton of miles, but it's like 8 seasons of total riding around here for a guy with a job. Yes some people have issues, but to go through that many rebuilds in so few miles, across 2 sleds - you have some combination of horrible luck and/or some operator/wrenching issues in play.
Just stock motors. Not LR motors or RKT. Stock. Oil pump turned up. Polaris racing oil only. 1ounce per gallon of fuel in the tank. Last blow up was most definitely caused by dealer in my opinion. But chipping rings and knifing Pistons are just plain Polaris. Hoping dealer didn't f up the complete rebuild this time and MtnTek fix kit works. I had over 3000 on my SLP rmk 900 and nitrous. Poo has 1/2 the top end life span of Doo or Cat.
Not trying to get in a pi$$ing match with any one. I just have not seen any longevity with poo 8 motors.
