Alternative ignition for twisted Breganzie twins

[Highflyer]

You've got a lightened crankshaft in it?

No, it's the original '70 750S crank.
I've read somewhere it's that heavy - might be mistaken though.
Sure did my back in when handling it

Cheers

It's heavier.

SF crank is 15, GT 17.
Disc SFC is 10,5.
I can't remember what the S weighs.
