I think you would get more and better responses by posting this question under "Tech Talk". Not that John doesn't know his stuff, he does, but he has never owned a SkiDoo Rev and you'll want to hear from people that have.
I have never owned a Rev either, but they were a good sled. There were some engine issues (rings) I believe with that model year, but you'll get lots of good feedback if you post this as I suggested above.
