1999 Yamaha Big Bear 350 4x4 Won't Shift
I recently bought a 1999 Yamaha Big Bear 350 4x4. The previous owner put a new carb on it. It was a crappy Chinese carb that didn't work well, and as a result, the bike would barely run or not run at all depending on the day. At first, I wasn't sure the "new" carb was the issue, so during the process of troubleshooting, I took the engine cover off to check the flywheel/other components for damage/rust. I took the stator off to get tested. After putting everything back together, I finally wised up and sprung for an OEM carb and had it rebuilt. After putting the OEM carb on, the bike runs great, but now it won't shift, and while it's running, there's a sort of grinding noise that sounds like its right behind the engine cover where the pull-start/stator/flywheel on. It's not a terrible grinding noise, but it definitely wasn't there before I took the stator off. Any thoughts as to what it might be?
