Last rode my 1999 2 weeks ago. Have never had a problem before. 1 year old Yuasa battery. New OEM R/R installed last year just to cover all of the bases. Went to fire it up today, cranked slowly, didn't fire. Plugged in the battery tender and will lift an ohmeter from work tomorrow to check the voltage across the battery terminal when running. I can hear some bubbling/crackling while the battery is charging. The only thing I can figure is my last ride was really short and I ended up idling in traffic for a while. Then, sitting a few weeks resulting in a low battery. However, this seems a bit unlikely. Something else sinister going on? No melted wire evidence that I can tell. Any help would be appreciated!
