First I had a Shorai in my bike, it sat for 3 months, dead. No way to charge it so I bought a cheapo Autozone replacement, actually I bought 2 and put one in my Yamaha FZ1 at the same time.Rode the MV quite a few times, no problem. FZ1 just sat other than an occassional start up. Anyway, my brutale sat for about 1 month, dead battery. Jumped it off, ran it for about 2 hrs, started up good multible times. Next morning......click click! WTF? Any ideas on what could be causing a drain?
