We have 03' summit 800HO that I need some specs on. Bought it used, ran like crap at altitude so we tore it down. No scoring or sign of a seize but the pistons looked like they had been hot. Kind of a silver/blue tinge on the inside of the pistons. At 1000' we had 130lbs. of compression cold and it dropped to 100 lbs. when warm. Anyway we're going to try a new set of pistons and hope the rings seat. The carbs had 370 jets and that seems small to me but I need the factory jetting specs and the torque values for the cylinders and head. Thanks
