For this build we use a deck height ARC billet rod and flat top piston combo, an E-Start ARC billet flywheel and a .272 Mongoose camshaft. The head is ported for increased flow. 26# springs and Champion Rockers are installed for max performance and easy valve lash adjustment. A 22mm round slide carb handles fueling needs. This would make an awesome rider/cruiser engine for a mini bike (direct replacement for Hurricane Pro) or backyard kart. Approximately 15HP. 87 octane pump gas.
