Just bought a 2004 919 has been sitting for 5 or 6 years. Pulled the tank and cleaned all the junk and gunk out. Put on a good battery and I get nothing. No lights, horn anything. Acts like there is no battery.Checked the fusses they all look good. No obvious problems at any conections. Is there a common problem that will cause no power, or do I need to look deeper. The bike was running when parked or so he said.
