SERVICE RELEASE N3/09

NATURE OF RELEASE: Instruction to riders. MODELS AFFECTED: All Commando DISTRIBUTION: Worldwide (General distribution) EXPLANATION: There is a growing tendency for our customers to neglect turning off the gasoline (petrol) supply when the motorcycle is parked. Whilst the carburetor float needles control the fuel level during normal operation the manufacturers do not guarantee that the needle valve seat pressure is sufficient to revent fuel passing through the carburetors whilst the motorcycle is parked. This results in neat petrol draining into the engine and joining the lubricant causing both a potentially dangerous situation and inevitable engine damage due to dilution of the lubricant.   ACTION: Instruct each owner to turn off the gas (petrol) taps whenever the motorcycle is parked. This instruction will be included in all future editions of the Rider's Manual. May 1972 Norton Villiers Canada Limited
