Have 05 Hayabusa 1300r that I am having a cranking problem with. I turn the key to start up and hold in the clutch and can hear the fuel pump kick on and all the lights turn on. When i press in the start button the lights got out and I can hear a click from by the battery area and noticed that when i attach the voltmeter the volts drop down to 6 or 7 until i let off start button. After I let off button all the lights and gauges rest. I replaced the rectifier and just put brand new battery in there over weekend. Any help you would help out alot.
