good performance upgrade or a bunch of sh*&^^?
My opinion is they are a little of both of the above...haha. Never actually used one, but as stated above, a "little" bit more power, and a higher redline. All my CB experience indicates plenty of available "redline" w/ the stock CDI. Perhaps I am lazy, but have accepted these little 200's for what they are, and haven't bothered seeking more power, I just try and keep em running in good tune.
Should one consider the long term reliability of running advanced timing and higher redline? I always thought of "racing" and long term reliability as being contradictory. :?
