The factory fuel mapping on these things is lean in the midrange. They have had reflash after reflash, nothing seems to work except putting on a power commander 5 and a map from either dynotech or slp which will richen them up. The factory polaris pistons have too much clearance to cylinder and rock, eventually scoring and breaking the skirts off. You still have warranty? Even so, I would get the "fix" kit from PMS in Idaho. Different wiseco pistons which actually fit the cylinders as they should. They are taller too and a base shim is also used. Myself and some other fellas on here have put this in, along with a power commander, it will be a different sled! look up the thread "some hope for the 800 cfi" for more info. good luck!
