You're just hoping. :D If you've got a nicely charged battery, try a normal start, but most likely you'll need to go to 3/4 to wide open throttle and keep cranking. Sometimes you get lucky and it will fire up. If you don't, then you need to pull the fuse and crank enough to get it to start popping and trying to start. That's your cue that the compression has come back up along with an oil coating on the cylinder walls.

Part of the problem is the wash down on the cylinder walls. What's in the combustion chamber will evaporate to a larger degree, but now the oil has been washed off the cylinder walls and the rings can't get compression when you first start cranking... making the new fuel coming in have a continuing wash down effect if you have't done the efi fuse trick first.

Yes, 8 off 10 times, a flooded engine will start when waiting long enough.
When trying, please full open throttle...

(seconds later...EricV beat me to it ;-) )

Update, Got home after letting it sit for about 4 hours.

Decided to try a normal start first (a short one as I was a little concerned about the battery after having cranked it for a total of several minutes this morning), didnt start.

Twisted the throttle all the way, pushed the button and it ROARED to life. No smoke, but I did smell gas this morning after it wouldnt start.

After it was warm, turned it off (switch, then key - sometimes I turn it off by the key, I will stop).

An hour later and then about 30 minutes after that, it started right up.

Thanks everyone for your help and info.

So I guess if it happens again, start with Wide Open Throttle (WOT - it took me at least 5 minutes this morning to figure out what that was, I assume I have it right now, please let me know if not!)

Hi Eric, question about the "Pop" you describe.

Is this like an electrical pop or a combustion pop or something else?

-- After re-reading your post I think you are describing more of a combustion pop, right? Although I think mine was popping like this all along, it sounded like it was really close to starting and kind of popping but not catching (it usually starts with a kind of pop pop roar, it just wasn't roaring this morning). But now it roars and life is beautiful once again.

I wouldn't worry about the shutting off the bike by the key, I have always done that on my bikes, and for over 65K miles on the S10. No problems.

Your good on the WOT, common way to start engines when they are flooded (to a point).

Yes, the popping is just combustion trying to take hold w/o quite enough fuel or improper fuel/air ratio. At first, the challenge is to get enough air into it to balance the overly rich fuel, then as it leans out, it starts trying to fire, and you get brief pops of ignition. that's your signal that you've got the fuel ratio down to where it wants to start. EFI fuse back in and re-attempt a start, going to WFO or 3/4 throttle if it doesn't catch right away and keep cranking.
