after refilling the oil tank after an oil change DON'T leave the dipstick/filler cap ever so slightly loose and then go on a back lane stormin' ride to test it. Don't do it coz you wont notice while you are having all that fun that oil is pouring out the filler cap going all over you, the bike, and when you eventually get home all over the drive (again). Don't do it coz only really stupid people do things like this :
