When I start up my 1200, usually on a cold engine, I get an intermittent noise in the front of the engine that I can best describe as a growl that lasts for 1 or 2 seconds off and on. Not real loud but I can hear it sitting on the bike. I can't tell if it's coming from the water pump or timing belt area but seems like it's low on the engine. I don't notice the noise after the bike warms up. Could it be the water pump bearing going out? The bike has 52,330 original miles. Anyone had this noise in he bottom front of the engine? I know it's not a good description.
