I don't know how long you've had your Wing, but everything I've ever experienced with Gold Wings is that after about 2-3 years, you're living on borrowed time no matter what battery, even on a battery maintainer. There's just something about them and the way they treat batteries; you'll be fine until the exact moment that it's completely dead and unresponsive.
If your battery was already dead and you had to use a jump pack to get it running, then your battery is too far gone. The plates are already sulfated, and no amount of fiddling will fix it.
Buy yourself a good, virgin lead, AGM battery (I *highly* recommend Yuasa AGM batteries with the sulfuric acid in separate tubes that you have to add yourself), fill it and charge the battery EXACTLY the way Yuasa instructs you to, and be on your way. Budget the money to do that every 2-3 years. Consider it a part of Gold Wing life.
(Experience: Over 120,000 miles on 2 different Gold Wings, plus a father who's been servicing Gold Wings as a specialty since 1975)
