The longest stop this winter was ~6 weeks because it took some time to get a new belt sprocket and get it replaced. That Yuasa still got so weak it couldn't start the engine more than once. It was less than 2 years old
Last winter it survived another 6 week break because of snowy weather without any complaint, I could FAS whole year without any problem.
I hate to dismember Teresa enough to remove the battery (that left fairing is a PITA to put back) but I won't let its successor to discharge this long anymore. Is it possible to recharge it while it's still in the bike?
