I've never had a CDI problem with my 03 America or my 04 Thruxton. Thought I did with the Thruxton, "Does one cylinder stop running when you lose power? If so is it always the same cylinder that stops running". The bike would idle fine and run fine for two blocks, then loss of power in a cylinder. Turned out not to be the CDI, but a bad float.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats. H. L. Mencken
