I have a 1980 SkidDoo GPS 500. The other day I noticed a metal bar with a leather strap attached, pointing out of the track area. This bar appears to have been attached to the front arm and a crossbrace near the front of the track. I am assuming it was some sort of device to maybe keep tension on the track. I know it broke off during my last ride and didn't hamper the enjoyment too much, but what does it do and how fast do I have to repair it? Can it wait till spring when its easier and warmer to do?
