Why do you need a new electronic ignition box? Is the old one bad? Just because you bored out your existing engine, is no reason to replace the CDI box, unless it is no longer functional.
You will pay mucho green at the Honda Dealer for a new one, which is the best way to go, if you actually need one.
You will pay around $75-$125 at a salvage yard for a used one, which there is no warranty and is gonna be just as old as the one you are replacing and may last the remander of the life of the bike or may drop dead day after you put it in. Used electronics are a 50/50 proposition, so tell me "Do you feel lucky today?"
