The engine is completely rebuilt with improvements throughout, giving it more power and better response without jeopardizing reliability. The pistons are short skirt sport pistons from V-Two to raise the compression. The heads got lighter 7mm valves with better springs, new seats and guides. From the Carillo rods to the 36mm carbs, to the polished crank to the billet cams to the smaller stem valves, all things were considered with this project.
