I have 2 sets of camel humps one is a ported 64cc set with accessory holes machined, and one set is 67cc with no porting and factory accessory holes.  Both are surfaced with new guides, screw in studs. I work at a machine shop and can finish if interested but just need to get rid of stuff in garage.   MAKE OFFER    330-6551 or 399-0076 leave message
