The M3W is no bike, and never will be.
Just buy one for what it is, and not what you wish it to be.
It really IS a toy,
Bear in mind also that the large engined 4/4 you have is quite a sought after beastie, so you would lose far less swapping to an M3W than the other way around..
Happy New Year, chum & good luck!
I'm with you Steve! Above an extract of your posting which is key to my relationship with the M3W
