Found this http://www.ebay.com/itm/New-Honda-1...741330?hash=item2820b9d492:g:a8cAAOSwmrlUyZdM http://v4spark.com/V4-config.htm $168 for the pair , programmable cdi boxes. Great if you want to run reground cams, benefit a couple horse from running premium fuel, or just want fresh new CDI boxes rather than chancing it with used ones. Programmable CDI boxes usually run around $300 for bikes / atvs. For that price you usually get a multipoint programmable curve, possibly a 3d timing curve based on throttle position . Pretty good price for what you get IMHO. Thoughts anyone? Should have put this in the products gadgets sub forum or what ever it's called ..mods please move if you see fit.
