Could someone help me? I changed my oil today and was also in the process of installing a Givi rack for my new top case when I heard a strange beeping or buzzing. It sounded like an alarm or something under the tank somewhere. I had the seat off and the key was in the seat release, not the ignition. I called dealer and they told me may be fuel pump. Does anyone have a clue about this?
Next time it happens, take the key and open the gas cap. It is the gas venting from the tank, if it is noise will stop the instant the cap is open.
Mine does it all the time, I doubt very much its the pump, but if it doesn't stop when you open the gas cap, I suppose it might be. No cause for any alarm its 100% normal, many bikes do it-my KLR 650 included.
