Got gearbox out yesterday after pulling 1/2 the bike to bits. Will try Petes suggestion of trying to rotate input & output shafts in all gears to determine if gearbox damaged

Input shaft rotates freely in neutral & 1/4 turn when in gear. Output shaft only moves 3 teeth in any gear. Its differcult to change select gears above 2nd. Conclusion damage is in gearbox. Is it worth taking rear cover of g/b off to see if damage is in there?

Or just leave it to the fellows with the special tools? I admit it would be tempting to have a look inside . . .

These are the nefarious recall parts:

Otherwise, as @pete roper said, "Perhaps the nuts on the end of the shafts have loosened/spun off? That was the issue with the last V11 box I was buggering about with . "

Imo...Send it to Pete, obviously its the gearbox right? ...and put a new clutch in while you have it out, best time to eliminate that potential problem (I assume you have the aluminum flywheel?). 

Best of luck!!

Perhaps your inbox has reached capacity, Pete? Time to delete off the older ones?

While the gearbox is out, good time to address a couple other important areas:

First, of course, is to disassemble the clutch to get eyes on the surface of the flywheel to inspect for cracks where it bolts to the crankshaft (image from Scura, c. 2016, crankshaft/forward side):

Also, a good time to assess/address the various leak sources in that space:

Okay, well, a couple other things . . .

Of course, a look/change of the swingarm bearings and that bloody-farking front UNI-joint  . . .

Docc, going by that photo, I think you really need to take more care about keeping things clean and orderly when you're working on a bike. :P:grin:

I'm off to talk to Vince Burrell about the gearbox who runs Guzzi Cafe near home. I think he only works on pre V11 Guzzis but worth the visit.
