While riding up in the UP ('02 ZR800 EFI CC) this past weekend I stopped after going through some mud and water crossings (little) and the rear suspension was in low rider form. I could pick it up but it would not stay up on it own. There was no evidence of oil blown anywhere or anything else I could see worng. The sled would go up and down w/ little or no force. The trails where real smooth so I continued to ride just taking it easy. The next stop the sled was back a normal ride height w/ just the little bit of sag that is normal. Is it possible the o-ring reseated? Or something like that? I can't imagine something would have froze up. I am real puzzled by this. The sled has 700 miles and none of the shocks have been rebuilt. Thoughts? Thanks, Dave
