Offset and deflection should be checked with a new belt for best results. Take it out and drive it, warm up the belt, then pull it into the garage. You're looking for there to be about 1" - 1.5" of "play" in the belt at the middle between the primary and secondary. The upper edge of the belt should be sitting just slightly out of the secondary (think: the thickness of a dime).

For the chain, that's simple... Loosen the jamb nut on the tensioner and screw the bolt all the way in by hand. Give it a good, solid twist to make it as tight as you can using only your hand. You're not looking to really torque it here, just get it tight. Then, back the tensioner off 1/4 turn, hold it in place, and tighten the jamb nut.

thank you meburdick i haven't actually tested them but from the messing with the belt it does seem like its got about that much play. also from memory im pretty sure the belt does sit about a dimes thickness out of the secondary.

what do you think could be causing the lose of top end rpm's?

Track too tight, worn / seized bearings in the idler wheels, worn our bad bearings in the jackshaft or driveshaft, chain too tight or worn, restriction in the exhaust, worn primary clutch buttons or spring, pitting on the clutch sheaves....

Basically, you have look for things that will impede getting all of the power to the snow. Look at things that can constrain the motor, bind the track, our anything else that would prevent the motor from getting up to full speed.

At a minimum, put the skid up in the air, remove the belt, and check out the general "easiness" of rolling the track by hand. Check the tension there and on the chain in the chaincase. These are all zero-cost steps.
