    Let me start by saying, it's a 2000 Harley Road King FLHR. Sometimes when the engine stops at just the right point, the starter has issues. It had done this since I owned the bike.

    I went to start it, and the way I figure, the starter is weak, and it was at the bottom of the stroke, so it had to put out some major torque to start the bike anyway. I immediately let off the starter switch, but I must have caught it at just the right point, because even though I let off the switch, the engine caught and started. I didn't think much of it until I was going down the road and heard a strange noise from the engine.

    I arrived at my destination, and when I hit the kill switch on the handle bars, I figured out the noise. The starter had been cranking the entire trip (5 blocks). And even though I hit the switch on the handle bars, it continued to crank. The engine would stop, but the starter would continue to crank. Here's where it gets odd: I had the switch on the handle bars in the "Stop" position, and I attempted to kill the power completely by turning off the main ignition switch located on the gas tank. The starter continued to crank. I continued to try this combination of operations to no avail UNTIL I put the transmission in neutral. After that, the starter stopped. I let the engine rest a minute and attempted to restart it, and got no response from the starter. On the 3rd attempt, the starter cranked, the engine turned over, and started as though nothing ever happened. No problems since. Please help me diagnose inmates!

    Just gotta love a helpful response.

    Wish I could help more. The first part doesn't really sound that abnormal. I've had that sort of thing happen on my Duc a bunch of times. I, like you, think that in my case at least, it just depends on which part of the stroke the engine's at when it stopped last. I've heard other big twins do something similar.

    But the hung up starter issue? I have no idea. Perhaps an issue with a relay, or solenoid? Or perhaps the start button itself?

    Not sure on Harley's actually, but the kill switch on most bikes just kills the ignition but not the starter circuit. A lot bikes will crank over when the kill switch is in the off position. I've done this intentionally numerous times for various reasons when working on bikes over the years. But the main ignition switch (keyed) should disable the starter button, although I don't know where in the circuit it actually interrupts it. I also have no idea why shifting into neutral would have affected this in any way.

    Geesh! I have no idea on this one. Sorry, but good luck on finding the problem. Probably something simple that I'm just not seeing....

    relay :nod

    My '85 K100RS did that once, but it never started, just kept spinning trying to start.... the starter continued to turn after turning off the key and pulling it out - until the battery was drained.

    Was a faulty relay.

    Sounds like the starter relay is the culprit, replace it.

    Yeah right. Just spent $295 for a new fuel pump/gasket for my 2010 WR250R. It's got 3500 miles on it and has been having starting problems since about 2000 mi.

    Yamaha didn't "fix" the fuel pump issue until recently, so just about every 2008+ WR250R/X (and some Husaberg's I hear use the same pump) is living with a poorly designed, unreliable fuel pump. The jury is still out as to whether the new design pump impeller fixes the chronic fuel-pump death when the bike warms up.

    And Yamaha didn't recall the US bikes, only the Japanese ones, for the defect.

    I'd have double the mileage on the WR if it weren't for the unreliability issues; the bike let me sit twice.

    I almost had to tow it home with... my Harley. :D

    Anyhoo, BigDrig, do you have the factory service manual for the FLH?

    I have the one for the newer bikes, once I get home I will see if it has any debugging info in it.

    Just had to do this did on my 04 FXDXI after it exhibited similar behavior. It eventually refused to turn over and I had to push start it. I decided to just buy a new starter relay (couldn't believe it only cost $6) and problem solved.
