| I believe that original gallery plugs are aluminium but they can be replaced with a steel one. I don't think the steel ones are known to back out so if the bit of whatever in your first pic is magnetic then its not the crank plug.
I suspect is alternator or gearbox related.
The only way to find out if you have a rocker problem is to take the cams out and then take each rocker out.
Like i've said many times before, rocker removal is not part of the official ducati service schedule. People like Neil at Cornerspped however do take them out and check them. |
