This is a CNC machined all steel billet 14Lb flywheel for the front of the crankshaft. Wheel measures 7-1/2" in diameter. This is exactly the same as our steel starter pulley without the belt groove. It is used with engines that use a starter to start the engine and do not need the belt groove. Heavy weight on the crank gives the motor the extra “Grunt" at the end of the track. Pulley includes a browning style tapered lock bushing. In the drop down box please select the crank size.
