has anyone had problems with the edge suspension? i have a 2002xc600sp and i find the suspension needs work. I got the dealer to put more pressure in the rear shock but it don't help. at first i thought it was better, but that was short lived. It used to bottom out badly. Springs are at max, now shock is at 250lbs,(which is max) It seemed better but short lived. I think the shock needs to be rebuilt. My sled has only 1500 miles.
