If the thread damage isn't too bad, it's possible to use a tap and die to clean them up a bit. I have done this several times before. I always tighten the bolt as far as possible with my fingers, this makes sure it's seated properly. Other than that I agree with 08BusaKy. I actually got mine on backwards too, works on the clutch side but creates a mess on the throttle side if I remember correctly. That also doesn't look like a stock bar mount?
