I have a Polaris 280 that I absolutely love. I have named him Mikey because he will eat just about anything. However, I think it's about time to give him an overhaul. Last year he was acting up(drive gear not engaging and slipping) so I took him apart and made some adjustments to the drive gears and wheels and was able to get him going again. Unfortunately at that time I adjusted him as far as he would go. So now I belive it is time for a rebuild. Any of you have any experience with this.
