cylinder kit Italkit 50cc for Hyosung AC Cab, Avanti

Very robust and slightly more powerful 50cc grey cast iron cylinder kit for air-cooled Hyosung engines without a catalytic converter. A good alternative to defective original cylinders and as an inconspicuous tuning modification. Delivery does NOT include a gasket set! Proper installation requires a new head and base gasket. Hyosung original parts can be order from the list below. The original head is retained.
