Suggest that the owner walk the sled out of the hole, instead of ride it out. After packing down a new firm platform, from which to launch from of course. With 3 positions available for the limiter strap, I found the optimum to be at the 1 1/2 position. With the no. 1 position being all of the way out. Then you take off the polaris stock track, pour gasoline on it and light it on fire in your back yard. It will help keep the sceeters down, and you can do some carbohydrate loading prior to attempting to put your new track on, by roasting a few marshmellows. Then you go to Tracksusa and buy yourself a camoplast challenger of the same size you just toasted marshmellows on. Although changing the gearing will help get maximum RPM on hill climbs, it will likely not help much to get your client out of the ditch that he just dug beneath his sled.
