Bultaco74 said: ring, and cylinder will experience much greater wear. by Robert Hodge Sun Feb 15, 2009 6:58 pm, Post Another problem with a cooler Itinerant Air-Cooled. There are two Thermocouple lengths - 4.5m and 6.6m - with cables suitable for 12mm and 14mm Sparkplug fixings. The head temperature gauge, which is commonly found on air-cooled engines, displays the work that the engine is doing more quickly than an oil or water temperature gauge. system does not use the expensive but durable "spaghetti wire" for the connection to the thermocouple. The tachometer electronics are very sensitive and will always pick up the spark. Air cooled aircraft engines (which always have CHT gauges) typically have maximum allowable Cylinder Head Temperatures of around 350-375f (about 175-185c) which is well above the boiling temperature of water. Aircraft engines can provide thousands of hours of reliable service, provided that they are maintained and operated properly.
