HiLD,Im no expert on magnetos,but I'm pretty sure the K2F is for the twin cylinder bikes.There is a unit suitable for the Lucas M01 mag that will make the conversion you are thinking of doing.Personally i would get the M01 sorted and use that.
You are probably trying to get a sixty or seventy year old piece of kit to work,it's not going to happen.Here is a unit, Ebay 151353125557,
priced at £155.00 this is what you are asking for.For a bit more you can have the real deal,with a garuantee,and perhaps another sixty years trouble free sparks.
Sorry ,had a few beers ,cant spell garantee,tried a few times ,had enough.
cheers Rick
ps,there will be plenty of recomendations from members,this is to be expected.
I just Googled "magneto repairs" and there are lots of them eager to sort your unit,ie http://www.themagnetoguys.co.uk/,never heard of them,but read on,
check out their (back to that word again)

Hi Rick,
U was almost there.
All U missed was a "U" for the Guarantee...
By the way,
BT-H Components Ltd, UK - ( HTTP://WWW.BT-H.BIZ )
Tel:01908 550044, Crown Way, Cardiff, CF14 3UZ
Manufacture self generating magnetos, electronic, of 100% new parts.
No points, and a choice of auto advance or fixed spark timing model.
No battery needed. I saw an impressing demo at Stafford,
Of generating sharp, blue and crisp sparks. It was impressive..
Other benefit to this mag is an ignition cut-out wire
And a locking mechanism to use upon install, so you do not have
To install it 6 times in order to be close to the correct BTDC point.. 
Only problem: Expensive / dear..
Cheers,
Noam.
