Stumped

I have an 07 zx6r with 17k on it. It got left out during a huge downpour the other day and hasn't run right since. It is idling low and rough, smells really strongly of gasoline and is blowing white smoke...not thick but white none the less. It is not getting as hot as normal. The temp doesn't seem to get above 180 and it's hot here in Florida right now. I added new fuel and a small amount of additive thinking maybe it was water in the gas but that didn't seem to help. The bike has run like a champ until the downpour. Any ideas?

Dump the gas and replace with fresh. Pull the tank off and remove everything in there. Pour that through a coffee filter, and see if there are any chunks in it. you're looking for rust and debris which can clog injectors.

If it's not running well, it's typcially going to be a fuel related problem; in your case it's more likely that it's electrical as you have a strong odor of unburnt fuel you're dealing with. Could be one of the coils is wet. The stick coils sit right on top of the spark plugs. The one furthest downhill when the bike is on the side stand is the one that has the greatest chance of collecting water and grounding out.

since you'll already have the tank off, it's not that much more difficult to pull off the airbox and access the plugs. Good time for new plugs, too.

Spot on advise.

It would be a very good idea to use compressed air to blow anything out of the wells the spark plugs are in, before you unscrew them. Anything that remains in there, will fall into the cylinder when you unscrew the plug. It may also be that your spark plug wires are degraded where they plug into the stick coils. If you see any wetness anywhere on the wires, that's a likely area for a problem.

Also, when you replace the plugs it would be a good idea to use anti seize on the threads. Steel plug bodies and aluminum will corrode together.... This happens faster in the presence of rain water, especially with salty air and high humidity.

Thanks guys for the advise. I have a compressor I can use to clear everything out. Do I need a special tool to remove the fuel lines or anything?
