A little heads up I figured out on this bike, thought I'd share so others know the solution and don't waste their time doing more serious work.
1) If you leave something plugged into the OEM accessory plug, it will slowly drain your battery. Usually not enough to cause harm, because you'll ride and put charge back into the battery, but in some cases you can drain the battery. Yes, even though the accessory isn't showing that it's charging, it is in fact draining some of the juice from your motorcycles battery. So, unplug your accessories when you park the bike
2) If you drain the battery to the point that no lights turn on, no dash turns on, and obviously the starter won't turn; Charge the battery. I charged it at 3AMP's and it took a solid 6 hours, though you can probably get away with 4AMP's. The lower the better, just realize that a "Battery Tender" or similar item is likely going to "charge" at a very low 0.5-1.0AMP, which will take between 20 and 40 hours to fully charge your battery (our stock battery is around 20MAH).
I'm aware most of you already know #1 and #2, but here comes the part I found interesting:
3) When you have sufficient juice in the battery to START the bike, you may find that the bike idles completely fine but when you increase RPM or attempt to hold a steady RPM, the check engine light (actually called the programmable fuel injection light) flashes and the bike begins to run rough. Why? I have no idea, perhaps you have enough juice to start the bike but not enough for it to properly run the fuel injection. Or perhaps when the voltage was low and I started the bike, it threw a "code" and put the bike into "limp mode."
Who knows, all I know is the manual says to take it to the Honda dealership and have them fix the issue. I fully charged the battery and still had the issue. I did not want to take it to Honda... so what I did was remove the battery from the connectors and let the bike sit for about 10 minutes. I figured this could "reset" the ECU. I then reconnected the battery, put it back on a "Battery Tender" (not a regular charger as I know it was fully charged) and waited until it was 100% charged again for safe measure. Started it back up and walla, works perfect.
So, sorry for the long post, but if you smoke your battery for one reason or another -- charge the thing in full and then let it sit while disconnected from the bike for a few minutes -- then reconnect it and start it up. I'm sure this will reset your ECU/FI and all will be good to go.
