Have owners of Vincent twin engines mounted in a Norton Featherbed frame changed the crank balance factor? If so what figure did they find best?

Norvin Balance

This subject came up in a conversation that I was having with Steve at Maughans. As I haven't got a Norvin (yet) I didn't take too much notice of the figure that he quoted but it may be worth giving him a call, Number in back of MPH

Wideline-Slimline

Imagine the original wideline Featherbed frame as basically two tubular "loops" parallel to one another. The slimline had the tubes bent inwards at the nose of the seat area to give a less knees out riding position.
