Mate of mine had a 600 years ago and rode from an army base in Germany to his home in Kent in appalling weather conditions. He was asking me why it might be running rough, as he was fairly new to biking anyway, and when he finally decided to take it to a mechanic they found about a litre of water in his fuel tank due to a leaking fuel cap seal.
Still amazes me how he travelled so far but presumably the motorway riding and higher revs would've helped disguise it a lot, although it may have leaked even more when he parked it up back at home.
Another reason might be a leak into the spark plug from washing the bike, primarily using a hose. If spark plug seals are knackered, or the plugs are cross threaded, a burst of heavy water could possibly get into places where water doesn't belong. I'd make sure the water drainage holes on the fins around the plugs are not blocked too, otherwise water could sit on top of a plug possibly causing rust and other forms of nastiness.
I don't even touch my bike with a hose any more, especially around the engine area, as i've had starting issues before after drenching the bike with a hose, and a long time ago i used an electric jet wash on it and it took a load of engine paint off forcing me to get a respray done, which actually turned out quite well so it wasn't all bad news.
