SALE - RCMK 57cc Twin Top End Set Pull OffRegular price $279.00
This is a brand new set of 57cc rcmk twin top ends and includes 2x cylinders, 2x pistons and 2x rings as shown in the picture. The sides of the cylinders have been machined to be a direct bolt up on a twin and can not be used as a replacement top end for a single cylinder engine. These top ends were pulled from a brand new CR600B engine that had not been run. Because they were pulled form an engine we have them listed at a $100 discount. Top ends will need to be cleaned before assembly.
