OK...so i have a 1996 Polaris 500 4x4. It was working fine it had a little bit of problems holding the battery though. So i would have to pull start it but one time when i pull started it the string wouldnt go back in but it started and it started to make a loud clanking/grinding noise from around the pull string area just sitting there i wasnt riding it or anything but it started doing that out of nowhere? could i have broke the gears or what?? any idea will be appreciated! thanks.
