Bought these a while back, im taking a different direction with the build. They are brand new, sent to Rob at RDZ for a full drag port. About $1400 into this combo.. Asking $1200 OBO shipped with pistons, rings, bearings, circlips. PM me if interested! These are very nice cylinders, have never been mounted or anything. I can also powdercoat them for free if you want.
These are 421cc with a +4mm crank.
