With a weak battery...
... could the motor turn over and sound like it's trying to start (somewhat quickly), but not actually fire?
When I bought the bike used in March, the bike was dead and the previous owner had me jump start it to test ride it. I got home, trickle-charged it and it's been fine since.
But I haven't started in in about 2 months, and after installing the new bar risers, the bike won't start.
a) I horked a wire on the controls when yanking the bars up and back
b) The battery has lost the ghost.
I tried jump-starting the bike off of my Triumph (which, by itself has a crap battery and starts slow ) -- and I didn't get more than one or two minor-coughs like it was trying to start.
I verified the kill switch was off --- with it in the ON position, the bike did nothing. So I'm pretty sure I didn't hork the kill switch; I verified the wires on the clutch side were plugged in.
I have a new battery that I purchased the day I got the 919 home thinking I'd need it, but it's not been used. I'm charging it tonight.
