i dont know if this is a stupid question or not but when my bikes not running the oil level on the sightglass is a tiny bit below the full marker which is fine. however when i turn my engine on the oil disapears completely from the sightglass, is this normal?
Also when my bike is cold or just warming up i can hear a knocking noise like a tap tap tap tap tap tap, when the bike warms up it stops? is this ok or something i should worry about? my bikes a 2002 bandit 600
