2007 Honda 919 wont start Kicks over but will start?

I have a 2007 Honda 919 I have been using as a track bike. I have never had any issues with it at all. I did not ride it much over the winter but I did get it out a couple of times. I am now preparing for a track day and for some strange reason it will not kick over.

I replaced the spark plugs last year at 8000 miles which is early based on manufacturer recommendation.

I am not a total newbie and understand you need fuel, spark and compression for a bile to start. I have all of those yet still will not start.

I do have a power commander installed but it appears to be working properly.

Do these bikes have a fuel filter that may be plugged?

Looking for a bit of assistance. Happy to pay if you can help me figure out what I am missing.

So the bike turns over but won't fire up? correct?
Does the fuel pump start up when you turn on the ignition?
Are the plugs wet with fuel after turning it over?

Check all of the connections on the PCIII first. Battery next, could be enough voltage to turn ovr but inadequate to start.

I had the same problem after a small fall. I thought it was a "tip switch" but it looks like it might have been the kill switch.

Flick the kill switch a few times and see if that makes any difference.

Is the crank a "straight line" cranking or a "we're trying, almost..." cranking?

"Straight line" is usually electrical, "almost catching" is usually fuel.

If you can post a few min of cranking with some good audio, that can help. IDK if the PC has any visual feed back, but I'd look for that.

One other note: You can get a build up of fuel in the exhaust that will explode once she fires up. Be careful of that.

Will the bike start if you hold the starter for about 8 seconds and give it a little gas? If so, search out the thread about Cold Start issue solved. It is a power commander issue. A 5 cent diode and a little solder will fix the problem. I have had this issue since 2006, when I installed the Power Commander. I installed the diode last month and it works like a charm.

pags, I'm stoked that the diode shunt fixed your cold start issue. Awesome.
