Polaris chain adjustment HELP
#1

Not sure of the particulars of a scrambler but I know I always
-compressed the rear suspension with a ratchet strap,
-adjust the chain to the tightness desired,
-tghten the swivel bolt.
-tighten the pivot point bolt
-release strap
why the chain is moving while tightening?...hhhmmm...how old is the chain and sprockets? an old chain that could have stretched will really give ya fits when trying to tighten it as parts stretch and other parts don't.

First does the chain have any side to side play,is it an older chain? can have trouble adjusting if it is.Whats really happening as you tighten the rear axle housing, it has a habit of twisting forward slightly which ends up loosening the chain. You can always tighten just a little more than needed, then tighten bolts on housing. should end up with where you intended. I always adjusted to where chain had about 1/2-3/4" slack at middle of chain at top of swing arm. I Didn't go by how the old manuals still said to collapse rear end and adjust,chain would end up being way too loose!(engineers agreed with me on this matter,this was used before the swing arms were re designed to lessen stress on chain,the front sprocket and swing arm pivot bolt are in line with each other which causes less chain flex from swing arm) Also jack up machine and turn rear tires and see if you have any hi or low spots in chain. If so maybe time to replace. OPT
