If you don't have one you'll probably blow up, revbox stops the motor from revving too high.

One of my friends dads (he's a real old guy, probably 55 or so) he says that old old old dirtbikes (when first came out) never had a CDI, and it would rev until the crank went through the case :eek2: , not too sure about that though. It would be safe to run one, maybe a programmable one, like DynaTek.

You didn't mention if you are hitting the rev limiter with the factory box. If not, a " Rev Box " will have nothing to offer.
