how bad does the sprocket have to be to get a new one fitted under warranty? Mine is showing a fair degree of wear at 1200 miles and the belt is quite vocal. It wasn't mentioned at its first service @ 950 miles but i have had a close look since and its showing signs of scoring on the teeth.
If you are still under Warranty, then no problem. It's two years, yes? Then smile, bow, be polite to everyone you meet, then demand it be fixed!
They, Morgan, blew it! If you can't hear yourself think while that puppy is screaming along then you have a problem! Or Morgan does. How vocal you are will decide this.
Man up!
