Cold Start problem on Speed4

Just recently when starting the bike completely cold the fuel pump runs and when it stops I'll crank it for a few seconds and she won't fire. The fuel pump then runs again.

Now, if I try cranking it again no joy, however if I turn the ignition off and back on (once or twice) and then crank it will fire finally (but not quick).

No hot start issue at all. Fires right up.

What does this sound like? Fouled plugs? Fuel filter? Battery on the way out?

Sounds like an everyday occurrence to me! If it is below 45F here it takes forever. Just keep letting the fuel pump prime. I had some cracked vacuum hoses and thought those to be the culprit, I changed them out, changed the spark plugs too, same old eheeheheheheheheh in the morning! Put it in a heated garage, then try starting it. If it starts fine I am correct, if it does the same, there is a problem.

If you rode the bike for a while and got it good and hot before shutting it off, try opening and shutting the fuel cap before trying to start the bike. It shouldn't matter, but sometimes it does. I suspect a vacuum in the tank when this happens. It shouldn't, but sometimes it does, and that's the fix.

It's a squid thing. You wouldn't understand.

Go soothingly on the grease mud, as there lurks the skid demon.

Got this from a previous thread... Ant find it now, but My speed four does the same at the beginning of the day. I turn the key, let the pump run, hit the ignition switch, won't turn over.

Try turning the key off and wait about 10 sec. Then hit the starter. I've done this the past year or so and it starts without fail.l
