PV. Go with a battery tender. I'm slightly familiar with that particular bike. Used to go through a battery every year, had one only last 3 months (cheap ebay battery, never go with anything besides a Yuasa, lesson learned) after I got the battery tender, that battery that is in there was 2 years old this spring, so 3 seasons on it. Hell, after 3 years, it may just need a new one... But get a battery tender.
And if I remember right, it won't charge the battery at idle, gotta rev it up a little, and I know you know how to do that,
