K1100 Won't Crank
« on: April 07, 2019, 02:32:08 PM »
Battery is charged. Bike is in neutral with stand up. Makes a high-pitched whine when I hit the button, but the starter doesn't crank.

All solutions appreciated.

greetings...

1) when did it last run... 2) will it bump start... 3) did you back spin it... 4) take a video with sound and post it here so we can hear it... 5) could be starter spinning and not engaging or could be the sprag clutch needs a flush amoungst other things...

Starter isn't spinning. Not a sprag issue, at least not yet.

Ran in November.

Flat here. No bump start.

Tried backspin, moving in gear, and trying to make the starter advance a degree.

What happens with the lights(headlight, dash lights, etc...) when you hit the starter button.

The battery's not the issue. I also tried jumper cables off a car.

Fuel pump spins but the starter doesn't.

Cranks fine. Starts fine. Runs fine. Idles fine.

Battery is toast.

These two quotes don't square. How did you start it?

Conflicting battery readings. Used a jumper box, and it fired up almost immediately after being parked since November.
