Hello everyone,
Just picked up a busa with 19k on it and when I test drove it, everything seemed to run like a dream. Fast forward to the other day when I made a crappy downshift without blipping the throttle and there was this terrible studder. The bike shook and made a loud knocking sound till it caught in gear (with the throttle). I've been able to recreate this, but only while downshifting by releasing the clutch with no throttle. I know this isn't proper, but I don't think it should be doing this either. It is worse in the lower gears than in the higher gears, but still there.
I have increased the idle to 1250 and that helped quite a bit, it was at 1000 before. I replaced all the cush rubbers and just replaced the chain. Sprockets look fine and I'll replace them both when they come in the mail.
Anyone have any ideas? Thanks!
