Thanks boys, I guess the best way to know is to try it. I can't believe how expensive a NOS Suzuki coil is....I've got a little stash of different NOS CDI coils I'll try 'em and see what works best. I'm not all that worried about the frame bracket Stuart, it's my Boyd and Stellings frame and it's got a bracket with a number of different mounting points, obviously for just the situation I'm asking about. I was getting the bike ready for the Nats so it looks like I can relax a little on the job now :'(
