So when I go around 25-35 only in high gear it will kick me out I believe and make a loud grinding. I checked the shift fork it was loose I tightened it and it still does it. And in low gear it won’t do it! I am clueless at this point give me suggestions I am mechanically inclined to fix it just can’t find the issue I was thinking that I the clutch slipped but there is no heat damage or slippage showing. It’s been going on since last year in the summer. Plz help thanks
