Fun one this. Changed the battery on my 03 FZ6s at the weekend and while I was at it checked the air filter, expansion bottle and sprayed some wd40 on and around the injector bodies.
Gave the bike a clean, put the battery on charge and stuck it in the garage.
When I came to use it the next day the engine turned over, fuel pump came to life but the bike wouldn't start.
Did a diagnostic check and there were no issues.
Thought sod it lets change the spark plugs as they need doing and it would give me an excuse to check the wiring and other areas, as those of you will know when it comes to spark plug time it's practically strip the bike down.
Having temporarily refitted the fairing and battery I found that with the plugs exposed there was no spark if I tried to start up with the button.
But they would spark up when I did another diagnostic check.
I've checked all the connections under the seat and battery box and found nothing out of the ordinary.
Anybody got any ideas.
Cheers
