I just got a kx250f and after I changed the oil it looks like its over filled. First I drained the oil and took out the oil filter, put a new filter in and filled with the 1.3 L of maxum4 extra oil. The 1.3 is written on the engine itself, only after I started the motor to get the oil into the oil filter and let the bike cool down, the little oil window still is completely full of oil. Shouldn't the oil be in the middle of the window after this is done? The last few times I changed the oil I used the window as a guage to fill the motor, not a measurement of oil like this time. Should I drain some out and use the window as a guage instead of the measurement? I know its a lame question but I just wanted to hear from someone else with the same bike that can make me feel confident or someone who has noticed the same problem. Thanks guys!
