I went ahead to change the lock over. First thing as I pulled the old lock out some of the key plates and springs dropped out the lock, please be careful if you have to remove the lock. Then after a patience testing game I put the plates back in the right order (after many permutations). Then I find the lock supplied with the bike does not fit in the V46, the hole is too small a further difference is a screw is needed to keep the Ducati lock in place, whilst there is a thread on the end of the Give V46 that has a nut to keep the lock in place.
Do not try this at home kids we cannot fly!
