In the meantime I have sent an example (my only spare!) of the blanking plug to Morgan to see if they have an opinion on it. Just to make sure the use of the plug won't upset something I haven't even thought of?
The blanking plug fitted to my M3W has remained firmly in place. I hope, wx permitting, to be at Beaulieu this Sunday for the 1000 Bikes (I hope they let me in with my extra wheel?). More than happy to let anyone look at my Torque Compensator Housing Grommet.......if you see what I mean....
