so my bike has been good since i had it, broke in my new top end, rode it easy, etc. then yesterday i took it out in the morning for a ride before going to the track, and it was making a weird squealing noise sounding like it was coming from the clutch. The noise was only in neutral and once in gear it stopped, so i decided to still ride thinking it was just cold, BTW i have clean tranny oil, and full so thats not the problem, however after about 10 minutes of riding i was in first and as i went to shift into second, the tranny locked up and the bike cut off. The bike will roll for a couple feet, and still shifts into and out of each 5 gears, and me and my buddies think maybe a tooth chipped off from one of the gears and is fiddling around in there somewhere. opinions would be appreciated.
