Helping my friend with his 2000 RMK 700 that is burning through hifaxes at an alarming rate. It seems to be the worst near the front where the skid has started to wear down as well where the slides are totally worn down. What could be the cause of this? I have heard loosening the track, checking track clips, and loosening the limiter strap can all help. Do tracks tighten on their own, because this didn't used to happen. Any other suggestions? Anyone got a favorite brand of hifaxes that last longer? Thanks!
