Starter button sporadically not working

[Lo]

Hello,

I've got a problem with the ignition on a ZZR600E. For the last week or so when I've pressed the starter button, about half the time nothing happens. I can hear one click when I press the button and nothing else. After a few presses, I can't hear anything at all. Then all of a sudden, I'll press the button and the engine will burst into life. This also only seems to happen when it's cold.

It's (probably) not the battery - took it out and charged it fully and still the same issue.

I haven't got the hang of the choke yet and sometimes need about 10 goes to get the engine to start so I wonder if that caused the problem... I can't think of any other stupid things I've done to it!

From reading around - it might be the solenoid, or spark plugs, but as this is my first real bike I'm a little clueless. Any suggestions would be very gratefully received

if you only hear a click it might be a poor earth connection somewhere in the circuit.
try cleaning/tightening the earths and see what happens

Firstly, we take our nomenclature seriously on these forums.
You are referring to the Starter Button. The Ignition is energized when you turn the key and the bike should be ready to start. Ignition refers only to the electrical system that produces a spark to Ignite the fuel mixture.
Start buttons are quite reliable as they only carry a tiny electrical load. Most probable cause will be the heavy terminal connection on the big wire on the Starter motor.
They can shake slack in use and should be checked at service times for this reason.
Best remedy is to remove the nut, washers and the longfon the motor. Clean the contacting surfaces with some fine wet or dry/Switchboard pad or similar. Connect it all together and try it.

If that doesnt do it then look at having the motor repaired or replaced . But it before that you may as well just ensure it isn't the Starter Button .

Bugger.... I forgot to mention the start soleniod. Same as motor. Clean and secure al connections.

But since you say you hear a click. Then that suggests the splendid is active. A splendid is a switch. It is way of controlling a heavy current using a small current. Google this shot fir more info.

Could be the starter solenoid.Have a check to see if the connections to it are all good and clean then check the solenoid a work shop manual will show you how....
