The owners manual has confused me, probably because I am easily confused. It states qty for periodic oil changes to be 1.15L, and with oil filter replacement 1.25L. However, it then states a total amount of 1.40L. My question is........ If I drain everything, including oil filter housing, do I put 1.4L back in? If not, please elaborate and educate this 2-stroker convert. BTW, I love the bike. It's absolutely awesome. Thanks in advance for your input.
