So I just wanted to be sure but I guess its not a huge deal but seems a bit odd from what I remember. When I turn the key to on the last few weeks she reads 11.9volts on my cheap man's voltage gauge and verified with a fluke (at the battery terminals) just today so apparently it is accurate. The moment I turn the ignition off she goes to 12.2 pretty quick and slowly climbs from there. Pretty sure I've never seen a dip below 12 volts when the ignition was off. Battery isn't that old (2 years in July) and the bike starts fine but... :doh:

According to your posted description of your added equipment, you are firing HID headlight(s) as soon as the ignition is ON, placing a drain on the battery at rest... even the std headlight would cause a draw, as it comes on with the ignition before the bike is fired up.

I don't think you have anything to worry about!

Sorry I didn't mention that part. Knowing HIDs hate flicking on and off often I actually hold the starter till the bike is running before sparking the HIDs but yes otherwise you would be right! I actually ordered a new battery I think this one is on its way out. I charged it fully one night for over 24 hours put it in the bike turned the key and was fine 24 hours later back to 11.9 after a moment blah... :giveup:
