08 cbr1k not starting after rain, help

So the other day I changed the oil on my 08. I put it on stands. I left it there and passed out. When I woke up I realized it was raining. My car port leaks a little, and it so happens that the leak was falling on the gas tank. Im guessing this happened for like 2 hours. I moved the bike and let it sit there.

Fast forward to today(3 days later) I start it, let it warm up and ride it to the gas station to gas it up. I put chevron 93 octane as always. When I go to start it it cranks very slowly but no go. I ask a guy to help me push start it and it does start but it sounds like its choking... It shuts off on its own before I can ride off. We try again and this time it would not run.

I bought a new battery thinking it was this, nothing. It now cranks cleanly and after a few tries it will fire up but it will act like its choking and die a few seconds afterwards...

What can it be? Bad gas? Alternator? fuel pump? water got into gas or shorted something> Any help would be very appreciated.

08 1k, 18k miles mods are slip on and pc

Was the fuel cap open in the rain?

I would drain the fuel, add fresh and try again.

You did put some oil back in it, correct?

No the fuel back was not open. I dont know if this matters but I hadnt ridden her in 2 months.

Not familiar with draining the tank, a how to?

And yes I did put oil in, I che3cked it 3 times already. The 08s are notorious for oil consumption so I have to keep an eye on that

Not driving it for two months will cause it to act the way it is. I am guessing you left fuel in the tank for two months?

I'd drain it and toss it.

Siphon it off with a tube, or get a cheap pump from the auto store (about $15).

Ok I know how to do that, harbor freights has one... OS just drain it out and then??? FIll with clean fuel and hoe it was that??

What issues could water dripping by tank, handles cause? Ive never dealt with an issue like this before

When it starts, it sounds like its only running on 3 cylinders and when I rev it it struggles alot. I just shut it off...

You could siphon it, refill it and add some SeaFoam to see if that works. I think that your bike has multi-port fuel injection, and I'm afraid that if it's running that bad you may have ethanol varnish in your injectors.

What issues could water dripping by tank, handles cause? Ive never dealt with an issue like this before Not many unless something isn't sealed correctly. Bikes function very well in inclement weather despite the fact that few people ride in it.

When it starts, it sounds like its only running on 3 cylinders and when I rev it it struggles alot. I just shut it off...Sounds like it's starving for fuel, which goes back to my theory of a clogged injector.
Just for grins, unplug your Power Commander, plug the ECU in directly and see if you get a different result.

Sounds like you have water in the fuel line clogging the fuel injectors. Happened to me after I washed the bike once. First drain the tank and fuel line if you can get to it. Fill with fresh gas and about 4-6 onces of rubbing alcohol, which is what fuel water remover is. Worse case you will have to pull the fuel injectors and soak them in injector cleaner and then put back together.

This new gas mix only takes a bottle cap full of water to make it separate and go bad.

DON'T PUT RUBBING ALCOHOL in your tank. It is cut with water (contains anywhere betweeen 9% to 50% water).

Stabil is a much better choice.

SeaFoam is a cleaner. Heet is a water remover. You should probably drain the tank and use both.

that is injector cleaner, shouldn't hurt unless you use to much.

I'd just start off with regular gas and see what happens. You can always add some injector cleaner later.

Use stabil if you let it sit for long amounts of time (months).

It did sit for 2 months but I would turn it on periodically to let the fluids run...

but did not ride it

Im guessing since it had so little fuel it picked up some debris or if not the water got in an electrical wire somewhere :(
