I have a brand new 2008 FJR1300A. I've had it since January, and I currently have around 1,400 miles on the odometer. Recently I've started to hear a rough thumping sound upon starting a cold engine that ceases after about thirty seconds or so. I don't seem to remember ever hearing this noise before. And I have had its 600 mile initial preventive maintenance taken care of. What gives?
