i don't think sparks or WB makes a CDI box for the 300. they do for the 400ex and they both make the bike hard to start. i went that route once and i will never do it again. i sold that pile of junk and got a GT Thunder one. i really don't know of a company that makes them for the 300. however, they really don't add much if any performance. they mainly let you go to a higher rpm before hitting the rev limit. this is mainly needed when you have a higher revving cam.

I think sparks makes one for the 300, but i know whitebrothers doesnt make one for the 300, only the 400EX. I would prob. only go with a gt thunder one, b/c from what ive seen, anyother kinds just tear stuff up. And like cals400EX said, it makes it very hard to start.
