Hi all,
I didn't take the bike to the service yet, but together with a friend who is a mechanic at the local Ducati service, we did a few checks:
1. With the engine stopped he moved the bike around and it changed perfectly up and down through all the gears
2. With the engine on (started into neutral) if you rev it a bit it automatically engages a gear !!!!!!
Even with the clutch pressed it cannot be pushed front or backwards.
So he concluded something is wrong inside the gearbox, maybe some washers/dogs/sprockets broken...
What do you guys think?
