I've tried just about every coil, and all the ancillary electronics to go with them. I and a good friend did just that years back with his bone stock 883 Harley, it was one of the flat tracker look alikes, I think 2003? After the Screaming Eagle coils, wires, and pick up coils, all I could feel was a little difference. To me, the expense yielded very little. What made this scoot come to life was when I bolted on the 1200 cc conversion kit, along with a Harley flat side carburetor, 44 mm I think. That bike when from Clark Kent, into a muscle bulging, tire screeching, front tire heading skyward animal. Bottom line, coils and wires do very little. You gotta put the whole package together to feel anything.
