Just got my 990 ADV 2007 home and got one question for you guys. When I turn the key to ON position, I hear a very ugly noise and I'm pretty sure that the fuel pump is making it. Seller left the gas tank completely dry, so I thought this may be the problem. So I put in gasoline to top and let the bike run for 10min, but the ugly buzzing from pump is still the same. I changed my CBR600RR 06 for this 990 and I'm used to clean bzzzz instead of bzshchszshzzshc, or is that normal?
