[QUOTE="greg brillus, post: 39601, member: 597"] Hi there, and thanks for the info so far. I think short of going to electronic/coil ignition and carrying a battery on board to power it (total loss system) then in the true sense of a magneto for racing you either go with a modern BT-H in either single or duel plug set ups or go with a Hunt type, I do know of a racer here in Australia who is running an original scintilla mag, the same as was used on the " Picador" this on a 1200 cc twin on methanol...a chopped engine in a road racing outfit, I even remember the engine number off it.....anyway I'm pretty sure that the SR 1 and Hunt type mags are made along the same basic design as the Scintilla. Having worked on many makes and types of magneto's, I can confirm that a Scintilla is by far the best made mag you will get, but saddly they are rare and this makes it not a practical choice if not for the lack of parts and so on.
