volts X amps = wattsI'm planning on some new heated clothes and wondering how many amps does the 109 have to spare??
Great suggestions Listan1. The only thing that doesn't get you is the draw for the ignition and fuel injection systems. Ideally you could jumper from the battery to the positive wire with an amp meter, and measure it running. You would need some way to leave it connected for starting as the starter amp draw is pretty high.turn on the key (don't start engine) and use an amp meter to read what the bike use
That's also perfect world, with no impedance considerations, not to mention voltage drop over wire run, etc, etc...volts X amps = watts
at 5000 RPM you should have about 13.8 volts divides 400 watts will give you about 29 amps (amps=volts/watts)
