I have a 300ex and the front sprocket has sloppy play, not in teeth but it wobbles and like wants to twist to one side as you release clutch, and each time I turn it release clutch the chain kinda pops and slightly grips rest sprocket tightly enough to cause racket, I was jus curious of why so much play on front sprocket it wobbles like is that normal cause my 450 doesn't at all neither did my 400 any opinions out ther
