I have a 1991 Sammy and someone for some reason converted it from fuel injected to a Harley side draft carb setup. Seems the MSD ignition that it came with was wired wrong or something because it's fried now. I am looking for a cheap or junkyard replacement if I can rather than spending $300+ Canadian on another MSD box. I do have a MSD blaster coil in it as well so if there's a cheaper ignition box I can use it would need to wire into my existing setup. Hope someone can help! Thanks!
