Five Hayabusa engines in the clean room, all awaiting parts.
The latest is a doozy. Bent countershaft, twisted mainshaft, bent teeth, dead dogs. Outstanding. Most smashed Hayabusa gearbox I've ever seen, (and I've seen many).
But all the gearshift forks are straight!!!! Client was changing from 2nd to 3rd whilst hard-charging when all of sudden there was a 'ka-lunk' and gears wouldn't shift. Shut it down and submitted for disassembly.
Here's the countershaft; as bent as Roger Rogerson.

The arrow to the right clearly shows twisting. The arrow to the left, brinelling from the hammering caused by the bent shaft twisting the bearing as it rotates and creating an oscillation between the two crankcase halves.
Check it out, that shaft is bent.

Braces won't fix these crooked teeth....

Dead dogs. Just about every dog had lost its edge.

I couldn't even get the gears off the mainshaft, it is seriously twisted.
Time to start scrounging for parts. Damn the see sawing Yank currency!
On a happy note, after threatening the supplier with a paypal investigation, Fineline got his Gen II mains and big end bearings. They have arrived. A rebuild thread is on the way.
