    I hate to make another thread about the same issue beaten to death, but I guess I just need clarification

    -Solenoid clicks when you press start
    -Ruled out neutral switch sensor
    -We jumped out the solenoid and the motor didn't spin at all

    Is there a way to test the actual starter? You would think it would at least turn a little or make some sort of spinning noise

    Kickstand sensor I'm pretty sure was also ruled out. Not positive. Neither me or my bud are experts, but we think we were thorough enough

    I don't know where to go from here. So frustrating!

    PS battery is good

    Thanks for any and all help

    good clean terminals? hot and negative leads n good shape? in my world the best way to test the starter is pull it off and bench test it. that being said. your motor turns over when you try to bump start the bike yes?

    It's raining and I havent had a chance yet. Obviously I have to try that before getting too into the starter.

    I just ordered a new solenoid for 19 shipped off ebay. Even if it's not going to last the test of time, I can positively rule that out.

    I wish I knew someone great with bikes haha. I'd feel much more confident about the kickstand sensor. I asotoq4htq9ghav

    If the starter does not spin when the two terminals on the solenoid are jumped you are looking at one of three problems. A bad ground, a bad starter, or a siezed motor.

    A clicking noise when pressing the start button, or jumping the solenoid indicates a functioning solenoid.

    Start by elimination.
    Siezed motor: Put bike in first gear and try to push the bike. You will know whether the motor turns or the rear wheel just drags. Confirm by removing the left engine crank/oil pump cover. Try turning the timing pointer with a wrench.

    Motor not siezed: Test Starter
    Test by connecting jumper cables direct from battery to starter. Postive to starter terminal, negative to starter body/engine case.
    If starter does not spin: Bad starter
    If starter spins. Remove the positive jumper, and try the start button/solenoid jump to check ground curcuit.
    ->If starter spins: Bad battery to case ground.

    The kickstand sensor will not keep the engine from turning over. Only from starting once it is turning over.

    Double-check on that, Ghost.... NONE of Mine will even turn over with the kickstand down, unless I'm in neutral. In neutral I can start them all on the side stand.

    I make it a habit of not having the bike in gear when parking/starting. So I may be wrong on the actual operation.

    But in neutral. The side stand switch should have no effect on the starter.
    Gotta give the OP enough credit to at least not to try starting the bike in gear.

    The starting circuit safety relays (including side stand switch and relay) will interrupt the signal that goes to the solenoid to close the contacts. But MiGhost is correct that if you jump the solenoid, there's nothing to keep the starter from spinning except for what he mentioned.

    I found out recently, there is NO ignition cut-off related to the side stand switch. The side stand switch is ONLY wired to your starting circuit, and gauges, but it does no interrupt your ignition.

    The start solenoid (which is just a relay) is used so that the wires that run to the handlebars (and all around the bike in the starting circuit) can be a higher gauge (and lower current). If you wired the started switch directly to the battery, and back down to the starter, you'd have to run that HUGE wire up and back.

    Shorting the contacts is basically wiring the battery directly to the starter. If it doesn't spin, it's got nothing to do with the starting circuit.
