Then I was told to check the bolts that linked the system together and make sure they weren't to tight and binding the linkage. They weren't... So if the springs are set to the stiffest setting the limiter strap is 3/4 out and there is no other obvious problems, when I sit on my tunnel it should REBOUND!!! It didn't, it just sat on the track. The spring should push the tunnel back up however i think the shock had some valving problems and would hydraulically lock up when fully compressed and wouldn't release or rebound. So I said just order the flipped shock and if I'm wrong I'll pay for it out of my own pocket. After waiting all winter it showed up, so I pulled my sled out of storage took it in and sure enough BAD SHOCK!! They fixed it under warranty no problem. Tell your dealer to order you a new one then when it comes in, take them your old one and they can compare the two. If they wont do that for you tell them you know a dealer that will and that's where you will be heading when it comes time for a new sled!!!!!
hotboat is right , this is excatly the problem, the vavling is shot, the heavyier springs people are installing is just compensating for the weak shock. dealer recharged first shock, still no good. installed new shock and it lasted about a week. after it sits in the garage for a day the rear suspension is very stiff with stock springs, but once you work the shock a bit it just sacks out and stays there. hope brp comes up with a answer so i dont have to fork out the money for a float.
the geometry sounds like it is also off a little which is helping the shock
