Hi there you magneto specialists, I'm thinking of fitting a magneto to my Norvin (twin) instead of the coil ignition, I have KVFs but would like something a little better, I've come across this Lucas SR magneto which is for a single but has asymmetrical magnets and corresponding pole pieces, surprising enough around the right angle to suit a Vincent, has anyone any experience with one of these (not SRs in general, just this one) and do you think it worth making a cam etc to try.
Chris.
