If you are looking to swap out your stock CDI box, the Big Gun Rev Box is an affordable alternative to highly-priced OEM replacement boxes. It increases the overall RPM limit over the stock box and advances the timing curve and is a direct plug-in replacement.

You must cut the green wire on the 8-prong plug going into CDI box.
