ok i have a problem ..i need to know how tight the track should be ....is there a measurement from bottom of slides to the track for the adjustment ?? i have a 99 sx and the rear of the sled is loose ....when riding it i can hardly keep controll of it ...cause it goes side to side a few inches like dog walking ....is it the track adjustment ? skis need shimed ? or limiter straps ...it is all stock with under 1000 miles on it ...w arm is not cracked ...what would be the best way to try to correct this problem ?
