I just finished my 03 wr450 supermoto. The engine has a 13to1 piston, ported heads, big valves and Vortex ignition. I have removed ALL parts associated with the electric start except for the battery. Vortex does not recommend using their box on this application without a battery. The problem is, when the bike is off the Vortex box Buzzes If I pull the ground wire it stops. Im assuming it is wired to have power when the On\Off button is pushed but I have removed it and jumpered it. Anyone have this happen to them and have a fix??
