The Super cyke will use many size props. 12/6- 13/5 would be good place to start. Depends on model and type running you want to do. you don't want to exceed 6500 rpm's. on ignition. These were well made in their day , but don't compare to modern engines. Don't use those aweful composite props on a ole gas banger. Good luck, Viking61
