Diagnosing difficult starting?

[Wynmead]

Suzuki Bandit 1200 K4
Bought Feb 2009, same battery since then.
Following happened yesterday morning and again this morning.

Ignition on. All warning lights and headlights on, gauges do their sweep.
Start. A turn of the motor then dead. Dead means all volts to zero.
After a second or so, warning lights back on, headlight on, sweep of gauges. No obvious lack of volts.
Start. Click and all lights off.
Again a second or so and all back on.
Start. Sequence repeats,
Start. Ditto
Start. A turn of the motor then dead.
Start. Click Dead
a couple more of these and then
Start. And she starts normally.

At the end of the day yesterday, started normally.

I use the bike most week days. Is garaged.
Brighter 90/100w headlight bulb installed some months ago.

I haven't checked battery posts etc and will do tonight.

Posting this now on the off chance the sequence of events I am having has been experienced elsewhere.

The battery has had a good run. Any comments on AGM batterys?
Thanks

I have a Mottobatt AGM, a fairly small one, and it runs my ZX6 fine. It's been left with the RFID ignition unit on for 3 months with no drop in cranking performance, cheap too :2thumbsup

Not the batt. Sounds like it is just a poor batt connection. That is not to say the your batt is mint tho!

battery connections or check the main fuse is tight in its holder and not got any corrosion>

Thanks for the replies.
Started after work last night no problem. Brisk cranking power.

Got home. Poles clean and connections tight.
Gave the poles a wiggle as one does

This morning started perfectly. Plenty of energy in the battery. Maybe the wiggle?

Have not checked main fuse. I'll need to locate that.
I'll do some more poking around.

if ya can wiggle them then they're loose, pull em apart and clean them well and assemble with vaseline or similar product

Certainly sounds like a connection issue, since the instruments are all flicking off, I'd guess its the battery terminals, or somewhere before the starter current, and harness connections go their separate ways.

Almost certainly some looseness somewhere - indicated by the complete -cut- and then return of power. Low or stuffed battery will just dim the lights while refusing to turn the engine.

That bulb will probably melt your headlamp unit. See trademe 566070586.
