A buddy of mine has the new 800 cat and while we were out riding you could hear a load ratcheting noise when the suspension was would compress while hitting jumps or holes. We thought the track was loose at first, but when we checked it was fair tight. At closer look the center lugs on the track were all chewed up but there was nothing in the track. Took it to the dealer and they discovered the limiter strap bolts were too long and in the wrong way so that on heavy compression the bolt would contact the track and chew it up. So Cat has gone good for the track and they put in shorter bolts and installed them the other way. Could have been a fluke manufacturing thing or an over site. either way I would check it out.
