Finally selling my OPEN 50cc motor. Was going to race it this year, but sold my bike, so no need for it anymore:( . This is a great motor that has been ported by Trevor Sellar (super huge porting in the case). Match ported with the New Bizeta 50cc top end. Standard crank, standard flywheel, Bizeta clutch, ect. Price is $550 plus shipping. Not bad, concidering the Bizeta top end was $250 for the cap and cyl alone and only has about 2 races on it. Produces MANNNY HoRsEPoWeR!:D Also I have a set of SAVA Mb's for sale, brand new for $100 plus shipping. Email me if you are interested!:D
