More of a for your information posting. I know there has been a lot of talk lately about coolant, especially in the 580 motors. I found myself loosing fluid. After I got done riding I could smell it burning. Look down by the pull start and the coolant hose has been rubbing against the pull start since day 1 and put a small hole in the hose. Probably something you guys may want to look for, it would really suck to find this while your out in the trails. At least it is an easy fix.
