I have a 97 polaris ultra 680 spx- the book says track tension should be 3/8 1/2 10 lb weight 16in from rear idlers. The mechanic at the shop says you can leave it hanging about a 1" to 1 1/4" from sliders in mid track without even hanging 10 lbs and that is how he sets them up. Well I have about a 1/2" without hanging the 10 pounder . I will not be riding til' janurary 11, 2002 so I have not test drove it yet, just wondering if others do the same. leaving their tracks with more deflections then specs.
