Took the 07 800 outty out for a spin today, and in high gear it made a grinding noise, like it wasn’t quite in gear, I rebuilt the gear case a few years ago and everything was fine, every other gear seems ok, so this seems odd, any ideas what might be wrong.

I tried adjusting the shifter and it doesn’t make a difference, I’m thinking I have an adjustment issue with the gear case inside, shim or something.

Any help?
