Exclamation Fickle starter

Background: 2006 GSX-R600. Has about 18,000 miles. Had some charging issues, discovered a bad rectifier and replaced it about a month or so ago. Battery is great.


Symptoms:
Most of the time, she starts up just fine, but I've had to push start her two days in a row. Both times it happened I had started the bike at least twice before in the same day with no problems.

Whenever she doesn't start, the lights go out like normal, but no sound is heard from the starter. All I hear is a sort of "whirring" sound.


What I do know:
Battery is good. Fuses are good. Starter relay is good. All cables to/from the battery, starter relay, and starter are good. And I'm pretty sure the starter itself is good (connected it straight to the battery and she cranked right up).


What I don't know:
Well obviously I don't know whats wrong! I can't seem to figure out why sometimes it works, and sometimes it doesn't.



Any suggestions? Thanks in advance

Also, I'm mostly sure the problem isn't the kickstand switch.

Sure sounds like the starter. On cars when they do that you cam tap them with a hammer and get a bit more life out of them.

If it is the starter, it is rebuildable. All is not lost. When you get it running again, check your voltage at the battery with a battery tester. Make sure it is in fact charging correctly. Voltage should go up when you rev it.

It runs fine, as long as I can get it started. And I'm fairly certain the charging system is fine, but I'll go through and check everything tomorrow just to be sure.

If it is the starter, well... I guess I get to learn how to take one apart and put it back together. So at least there is a silver lining.

Eh, I get tired of all those polls where we get to vote for boobies, but we never actually get any boobies. What's up with that, huh? Next time I make a poll, boobies will be an option, and boobies will be there!

I tested the starter relay, and it checked out fine. And its not the side stand relay.

I had thought maybe it was the starter button, but I don't think so anymore, because when the button is depressed, it kills the lights and "summons" the starter, but the starter doesn't click. There is just an odd "whirring" noise.

Now that you mention it, it sounds exactly like the fuel pump. noobs! Don't even know what a "whirring" noise is!

Check your ground wires. Mine was loose on my R6 and it caused intermittent starting. I torques down the wires and was good to go!

have you checked voltage to the starter when the button is depressed and it wont crank? because the starter itself doesnt CLICK, the relay clicks. Soooo it sounds like, from what you are saying, that the starter relay may test fine, but may have an intermittent ground issue, or power delivery issue. otherwise if it clicks every time, then you probably need to check the armature.

At the starter? No, I haven't.
I'm assuming it should read about 12v?

because the starter itself doesnt CLICK, the relay clicks.

lol, crank, not click. The two times it wouldn't start, the starter did nothing... at all. Lights went out, fuel pump activated, but not the starter.

Soooo it sounds like, from what you are saying, that the starter relay may test fine, but may have an intermittent ground issue, or power delivery issue.

I just now checked the ground. Connections seem good as far as I can trace it. Honestly, I'm not sure what to look for with a ground issue other than loose connections.

otherwise if it clicks every time, then you probably need to check the armature.

Yeah, that's unfortunate. I've been busy and don't have that much time on my hands.

Responses embedded in quote above.

I haven't ridden it since the last time this happened (Thursday evening). It's starting fine now, but I took a video of how it sounds... I'll post that up shortly. Perhaps a trained ear can pick up something I can't.

And:

Thank you!

EDIT: Just finished looking at the starter system diagram. Since there seems to be a consensus on the ground issue, I'll try to inspect all the grounds of the system.

If I do have to take it somewhere, I will strongly consider Motorcycles Unlimited. They have a great reputation and I like Patrick's involvement in the mc community.

But, it's so far. And I commute on my bike. So I would prefer if it could be done in a day while I wait there. Also, I don't learn anything if I take it to a shop. If a shop would let me be a helper while they work on my bike that would be awesome!

This on again and off again thing makes it seem like a bad connection somewhere. As mentioned before I would check and make sure all wires and connections and torques down. A voltage meter is gonna come in handy as well when and if it doesnt want to start again.

Update: Happened again today as I was leaving school. Pushed the starter button and nothing happened. While sitting on it, I rolled it forward a little, then as I was rolling it back I tried again, and voila! it started.

So that means its the starter?
