Hi Mr Bar yes that’s a Outlaw kart engine , but for what a real hotrodded Honda / predator / clone would cost to build on a mini bike . This deal starts with over 40hp of right now HP to begin with . Can be run on alcohol with no radiator for drag racing . I run a stock CRF450 In my UAS Outlaw Kart and its very quick . Cutting trans clutch off is 16-18lbs from a stocker at 62lb .An they sound sweet too .
