Around 5500-7000rpms I hear a chatter come from the front section of the bike. I'm pretty sure its rev related cuz thats the only time I hear it. I think its chain chatter possibly but I figure I'd ask and see what people say, anyone else have this? Might be a worry wart but I coulda swore it never made this noise the first couple weeks I had it. . . has 1700 miles on it.
