the untold problem 2008 09 polaris 800 eng failures

[timbo]

some people say they like it at 120 and some say 150. I don't really know what the better temp would be.

Does Polaris have a spec for operating temp that is programed into the ECM? Does Polaris publish technical info to the dealers?

I bought 3- 700's Brand New. All engines failed by 1,200 miles. One engine was rebuilt and lasted 83 miles. I just traded my blown 700 under warranty for an 08' 800D. I am petrified to ride the damn thing till' this issue is solved.

i would say there was an issue that caused the engine to fail in 83 miles. oviously it got missed during the rebuild.

What did they tell you the reason for the engine failures was? Mine was because of a faulty voltage regulator.

I believe my dealer had said it went into limp mode at 150, they say coolant temps above 150, detonation is more likely to occur. In the powder my does 126.
The top end just blew up on mine (mag side), number 3...even after the update. They haven't been able to tell me why yet. I run Shell 91 octane, with Polaris Gold Plus, and the Iridium NGK BPR9EIX plugs. I also have a MBRP can. It's never grenaded in the moutains, but I've had no luck on the flatlands...

May be the voltage regulator. They're known to be faulty and mine caused me to have to replace both pistons.
