Ok, I have an 06 700 that is blown up. Are there oversized pistons if I need to bore the cylinder? I haven't found any but I could be looking in the wrong spot.

Sounds like whoever had the sled never did the radiator delete or they never ran the radiator and rear cooler in a series. That was the worst setup I have seen Polaris do because the coolant is going to flow down the path of least resistance and most of the time it ends up not flowing to where you are going to get the best cooling. I would talk the radiator and run scratches or run the rad and rear cooker in a seriesOK,
If your following this, Cylinders look good, small scuff on both pistons below ring land ex/int/front side. I am going to replace the rings, clean up the ports and bolt it back together after inspecting the crank although it seems solid. It seems to have got so hot because the impeller on the water pump gave up. The water pump housing was also "torn". It appears to have been run without water until gasket failure. If the 700's overheat like the 900's then the problem is most likely over heating not oil starvation. Both sleds I got failed at the same time while riding together so my guess is 10 miles on an icy trail.
