*** is going on here. Every time i've changed my oil I get about 2000-2100ml's of oil come out and the same amount goes back in. I know my oil level has been at least a 'little bit' low. But 1300ml's? can't be as 1600 went back in and now its level.... but the question is where is the other 300ml hiding? I just took the bike for a ride so the oil was nice and hot. Didn't do anything differently to how I normally drop the oil. Let it sit on its side stand till the oil stops pouring, tilt it upright, tilt it to the right side, back on the sidestand and repeat 2 or 3 times.
