AJS & Matchless Owners Club

I have been searching for a long time, for a crankshafts, for a 1960 G9 with an alternator, with no luck, does anyone have experience fitting the adapter part number 650ca, that the club sells, to a dynamo crankshafts

I run a G11 600 with a adapter , if there is any run out once fitted I skim the rotor by upto 0.010"
I believe the factory also had adapters fitted on some engines
mine is loctited in position

Thanks for your reply
