Couple of days ago I went to start the bike in pitch darkness very early morning and the starter did nothing.
It just flashed up the yellow dash light, which I'm guessing is an engine light, and the red oil light.
I hadn't ridden it for a couple of days so pumped the clutch lever in case the clutch plates were sticking and a couple of goes later it started and all was good again, so i just let it go.
As I had today off I gave the battery a charger boost for 5hrs, and then I just changed the oil and filter as well.
Before changing the oil I let the bike tick over for 5mins to warm the oil up a bit before draining it.
When I was all done, I turned the key, and it was dead again, with just those two lights showing.
After about 4 or 5 attempts, and some serious staring, it then sprung to life again?
I let it run for a bit then switched off and on a few times and it was totally fine.
As it was an ignition issue I also gave the ignition barrel a good spray with some Contact Cleaner.
Question is, if this happens again and I can't get it going, where should I start looking for faults?
I had issues years ago with ropey starting, and the Contact Cleaner spray worked miracles on the ignition barrel, so I'm hoping it won't happen again, but if it does any ideas why as this specific problem is not something I have encountered before?
