For sale is a 2014 Bergfelt outlaw c51 kid kart engine. Engine has cut clutch shoes for a higher stall speed as well as faster pick up, Ports have been reshaped, Carb is a big bore, Flywheel fins have been cut down, piston has been lightened. This engine has been extensively modified and will not pass tech. But if you want to give your kid karter a chance to get use to the speed or if you have a track with no rules this would be a great buy! These engines sell for $1,500.00. I am asking $800.00. If interested call or text 214-325-4985 I can text or email pics Thank.
