Two small radiators are tucked away discreetly to dispose of heat extracted from critical regions between the valves and at the very top of the cylinder, where open-deck construction cools both the top piston ring and the base of the cylinder head. Cooled water goes to the pump at the front of the crank, then is circulated through the heads and returns to the twin rads. Apparent complexity above the engine is the coolant header tank and thermostat bypass plumbing."
