Help! Busa making knocking/shudder noise!

[Turbo Busa]

There have been a few cases of the clutch spring support bolts not being Locktited out of the factory and coming loose. This could result in a catastrophic failure, If it was my bike I wouldn't even run the engine again let alone ride it until I'd pulled the clutch cover off and unbolted the clutch spring set bolts to check if the support bolts were ok. If they come loose and rattle around loose, this is the sort of problem that could easily kill you if it locks the rear wheel while you're cranked over in a corner

Pull the cover and check 'em mate
