How old is the battery?
This is your 'barn find' right - a 2008 with only 500 miles on it?
So I would suspect two things.
First if it is the original battery, I would change it. If the battery is more than 5 years old, I would change it. If you have no clue on how old the battery is, I would change it (see a trend). Otherwise have a shop do a load test on the battery to see what sort of shape it is in. A charger and and voltage test does not give you a complete picture on the health of the battery.
Second, at the age of the bike and the low miles, I am thinking the fuel in that tank has sat for long periods of time. Couple that with the 2008 fuel pump then it may be a weak fuel pump issue.
Start at the battery first. Also check the top of each forum for the 'Stickys' since there is at least one that mentions a connection up on the front of the bike that may come loose and create all sorts of mayhem.
If you really want to get to know the bike then you should take some time to look through the postings here since you are likely to see some real good ideas and problem solving skills on display - FOR FREE no less! Google is your friend... unfortunately it is also the NSA's friend as well.
Others may chime in as well with some other good ideas.
BTW get a shop manual... it will be a best friend for you and the bike.
