If you can't be convinced to build an av10 but insist on having a reed valve, this is the kit for you. It is littered with ports with a generous exhaust port. The screw in exhaust mount is larger than your typical Motobecane so you'll have to fab something up. The fins are gigantic on this cylinder for maximum cooling. Total oddball cylinder with tons of potential. This kit comes with everything in the pictures.
These might not be around anymore after this batch.
