While waiting for 'normal times' to return, I'll start my K1200S and let it run for 5 min or so on its center stand. Twice there has been a quantity of oil (1/2 cup or so) on the ground under the front of the bike. With the fairing off the oil came before the engine, so I'm assuming the oil cooler. Today I did the same start up and--no oil leak. The dip stick in the oil tank shows normal level. Another assumption is that there is a thermostat that opens to allow the oil to return to the oil tank. Is it possible for the oil cooler to overflow if the thermostat doesn't open and the running engine is still pumping oil into the oil cooler? As always, thanks in advance!
