The x-300 calls for 2.2 Liters or 2.3 quarts of oil if you are swapping out the oil filter, which i did. I definitely measured the correct amount when i added it but the oil level is still quite below the minimum level according to the check window, even after running the engine for a while. In fact, the oil doesn't even make it to the bottom of the check window unless i lean the bike inwards a little bit. I'm not sure whether to trust the manual or to trust the check window level. Has anyone else noticed a discrepancy between the actual oil amount and the amount in the manual? Should i just add more oil or will i risk overfilling it?
