Hi, yesterday I decided to take my bike out for a little ride after it being sitting in my garage for nearly 2 weeks without me touching it.

I turned the ignintion key to on, waited for the gas pump sound to stop (zzzzzchin), then pressed the ignition on button. Bike came on as normal with a few chirps (which I assume is because of it being cold). And I just left it idling till it warmed up.

I then realised that I needed to open my spare compartment, so, roughly 1 min after initially turning it on, I turned it off to use the key to open up the compartment.

30 seconds later, I tried to start her up again. Lights came on fine, gas pump sound came on (zzzzzchin), then I pressed the ignition button, bike wouldn't kick over. :werd

Stopped after a few seconds, then tried again, same thing, bike would try to start, but wouldn't kick over. I tried about 5 times, nothing. It was as if there was no fuel getting pumped into the pistons.

On the sixth try, I decided to press the ignition button while slightly accelerating, which worked after a second try. After this, the bike worked as normal, went for my ride, stopped for a coffee/lunch, went on my way again without any issues.

Does anyone know why this happened? I've had the bike since it was born and have never experienced this. Could this be something to do with me not riding it for 2 weeks in winter?

Any feedback on my concerns would be appreciated. I've recently had my EXUP motor changed, but that seams to be working fine.

Cheers

When you first start your bike the computer is in open loop which means that is uses a preset fuel map. The cold start map uses a lot more fuel similar to how a choke works which gives her a drink, then you shut it down before the engine was up to temp and tryed to restart which causes a flooded type condition. When you open the throttle and crank you introduce more air to get the mixture to a point that will ignite. Once the o2 sensor warms up the engine is in closed loop which adjust the fuel mixture by oxygen sensor feedback.

Damn dude, thank you very much for the detailed explanation. I didn't expect to get such a quality reply!

Thanks again.
