New Pro: Replace pistons now or later

[Track Man]

I like to say first that I am a Polaris guy all the way and I love the Pro. I have a 11 and a 12. The first year on my 11 I blew the motor at 1,000 miles. The 2nd motor went at about the same miles 1,000. It has about 400 miles on the 3nd motor and runs great. No warranty left on the 11. My 12 blew up today with 1,150 miles on it. I have a 4 year warranty on it so there is no way Polaris is making any money on me. I run extra oil and always warm up to 125 before riding. I for one think there is a big problem with these motors. You Think. Now I need to fix my 11 before it blows on my dime. My problem is when they blow you never know were your going to be. Getting it home came be a big problem. Thanks Polaris.

When you say they blew, what happened exactly? Pistons break, crank, rod bearings, broken cases?

All 3 motors, cylinders skirt. All 3 at low RPM. and warmed up.

Personally I would blow off the warranty and spend the money on Indy Dan's Long Rod upgrade. If you get it to him before it craters, It's only $2500. With the additional crankcase volume it runs much better and feels like gaining 15-20 HP. If your not game for that much money, then opt for letting him size the cylinders correctly to the pistons for $1000. Either option is money well spent, it is unfortunate that we need to rework brand new production engines but those are the cards we have been dealt. If you want piece of mind Indy Dan is a pretty economical way to go. IMO

This is exactly why I put RK Tek's pistons in both of my Pros, even the one with 0 miles on the new motor.
