I have a '93 polaris indy sks that I would like to get the track replaced. I have the replacement track, but wanted to find a place in the valley to do the work. I would do it myself, but have never worked on a snowmachine before. I also wanted to see what the cost may be. I have one other question regarding the suspension. I am a pretty heavy guy and I bottom out the suspension on this sled. Is there a good aftermarket adjustable shock that would stiffen up the ride, so as to not bottom out the suspension? thanks for any advise you may have.
