Shiny new R6 Brakes
My R6 brakes came in yesterday, so after work I installed and bled them. It’s been a couple weeks since I started my FZR, so I thought I’d let it run for a few minutes, and...
It wouldn’t start. The battery is good, the fuel pump comes on, but when I hit the ignition switch I just hear a big clunk. The engine doesn’t turn at all, so I’m fairly sure there’s a problem with the starter. I have no idea why it would fail (If that is actually the problem) after working fine and just sitting for two weeks or so, but that’s old bikes for you I guess.
I have to pull out the fuel tank this weekend anyways because of a fuel leak at the petcock, but does anyone have any advice or similar problems?

Sounds like the starter solenoid doesn’t do it’s job ?
Are you sure the battery is good ?

Either the battery isn’t as good as you think it is or that s ta rter needs a whack with a mallet...

I checked it and it’s putting out 12 volts, I’ll start with the easy route and break out the mallet though

Could very well be, that’s one of the few electrical parts I haven’t replaced yet. Battery is putting out 12 volts though

I would have your battery checked. 12v doesn’t mean the battery can deliver the amperage needed to engage and turn the starter. The battery needs to be load tested.
You can wire two 9v batteries in a series circuit and get 18v at the end. That doesn’t mean they will start a motorcycle.
Cranking is all about amp erage
12v indicates your battery is charged , but doesn’t mean it’s a good battery.

what is it putting out when you actually hit the start button? a failing battery can show good voltage at very low current draw but will fall on its face when faced with the starter trying to draw 100 amps.

That’s a good point, I just checked it with the bike turned off. I’ll check again today

yep, the battery in one of my bikes took a crap. Open circuit after charge was 12.8 volts (“good”,) turn on the bike, it dropped to 11. something, and trying to start it fell down to 7 volts.
TOAST.

Push start?

Hit the positive post on the starter with a jumper wire to the positive terminal on the battery. That will eliminate any ignition components to check the starter.

Throw it on a trickle charger for a few hours, just to be safe. My old nighthawk would drain the battery if I wasn’t letting the engine rev fast enough so sometimes after a few rides I’d be “just” below the point where the solenoid wanted to kick over. Keeping her on the trickle charger kept it from being an issue.

Try jumping it anyway off a good/car battery, might give it more oomph

In addition the the hammer whack already mentioned, rock it back and forth in gear a couple of inches, possibly moving the flywheel enough to engage the starter?

If the battery is only putting out 12V it’s gone. A healthy battery would be reading 13.2-13.4 without a load. (over 13V, anyway)

There could be three distinct failures to puzzle through;
1. Battery is flat/bad and starter pulls in but does not turn over. - I don’t think this is it because if it is that flat, the solenoid should drop out as the voltage falls. Usually then it pulls back in and out making the starter chatter. If this were the case, your headlight should dim to nothing too.
2. Your battery connector is loose/corroded. - I don’t think this is it because in this case when the solenoid pulls in, the connector arcs/opens and you lose all connection and power. You then hear the solenoid pull out and the bike is dead until the terminal is tightened and cleaned.
3. You contacts are dirty in the solenoid or there is a bad connection in the starter slip ring or your starter has failed . - I think that is it. The solenoid works but either power is not going to the starter or it is and it isn’t getting to the rotor. Either way, the solenoid stays pulled in, your headlights are bright, but she won’t turn over. As the experts say, hit it with a mallet.

Make sure your leaking petcock didn't hydrolock the motor

Could it hydrolock the motor? It’s just dripping a bit of fuel where the petcock valve assembly meets the tank; it seems like it just drips down onto the trans and exhaust.

If it leaks external it can be leaking internal too
