lol wordslinger! wonder what would the top speed with a much shorter and lighter rider.
stock pulley can reach 8.4k rpm not sure if the malossi can too. it only reached 8k but when i checked the pulley a few mm still left on the drive face.
i saw on 1 site ther in the us that they sell racing cams for the mxu 500. will it fit our x500?
