KLEINE TECHNIKFRAGE #1: Under what circumstances is an oil cooler worth for an air-cooled two-cylinder machine, and is this even useful? And is a thermostat for quick heating and not to be undercooled in winter a “must have”, or senseless play?KLEINE TECHNIKFRAGE #2: If you install an oil tank distance ring to get 50% more oil (i.e. instead of approx. 2.6l now 3.9l) into the engine, would an extension of the interval from 7,500km to 11,250km be legitimate? NIKFRAGE #3: Let’s assume we’re going to the ass of the world. And by that I mean really ass… Is it justifiable to drive unbalanced tires there with regard to the lifespan of the wheel bearings? SMALL TECHNIKFRAGE #4: What happens if you suddenly double the oil change interval or drive even more? Instead of 7.500km tearing off 20,000km and only tilting the usual 0.1-0.4l/1,000km that the engine consumes anyway? “Something” of fresh oil comes in. And ok, the Plörre should then be full of suspended particles and thin like water. Whereby in advance only the thickest, temperature-stable oil (20W-50) would come in anyway. Possible, or not?
