How do I...
Check my Stator? Battery voltage went down while I was at the gas station with the raido playing. I bump started the bike and rode for at least 20 minutes and the battery never charged back up. Got home and put on the tender and now the battery is charged. I haven't ridden it again to check it out. Could it be the stator?

Disconnect stator leads and check for continuity (resistance) between each lead and ground. It should show open circuit, any continuity indicates a grounded stator.
Then check resistance between 1-2, 2-3 and 3-1 resistance should be very low, less than 0.2 Ohms.
You can also test voltage (AC) across the same sets of pins. With the bike at idle it should be around 20VAC (over 15 is fine), at 2k RPM it should be around 40VAC.

Agree with Dawg. First check the battery connections. Even the smallest amount of corrosion can affect the whole system. I usually disconnect the battery and clean the connections well at least every two years. A dremmel with a brass brush works well, but any brush will do I guess. I can't tell you if this is your problem, but it is worth a first shot. It has worked for me in the past. Maybe I have just been lucky and there was nothing else wrong.

Could be issues as stated above or a voltage regulator. Check DC volts at battery terminal with bike running. If you battery is stock, it might not be taking a charge anymore.

How long did the tender take to charge the battery? If it wasn't long then you may need a new battery.

Exactly - as annoying as it would be to have a bad battery it's a lot cheaper than some of the alternatives.

Also, it is worth a shot to check on recalls for your bike. Mine is an early 2006 model and the voltage regulator has been recalled. Last time I checked, they fixed the voltage regulator mid 2006 but who knows what happened since then.
