Thanks, that's what I linked to in my initial post though... had been following that.
GZERO helped me out a bit by phone, and made me realize just how crucial battery life is on these newer FI bikes.
Took a close look at the battery tonight, and it turns out its a Deka ETX9 (A Yusa YTX9-BS Equiv.) nowhere close to the stock YTZ14S.
Maybe I'm off here, as in the "Alternative Battery" thread, I notice some people are running a Batteries Plus equivalent to this ETX9... but I suspect that this battery is just too underpowered.
Think I'll be heading out tomorrow to grab a new battery. The question then, which one. Do I drop the $180 on the stock Yusa, or go the LiFePo route? Or do the cheap $90 Batteries Plus equiv. Choices.. choices.
Hope this solves the problem though.
