take the spark plug out and dry it off,its pulled water inside the combustion chamber and is causing the plug to short out,they,ll usually start after drying the plug off,good luck.
first things first did you put the bike away for the season and if you did did you run your carbs dry to where the bike would stall, if not you may have jelled your carbs if not then use some brake cleaner spray or either but let it sit for about 10 to 15 minutes so it can dry it will remove mositure then try to re start your bike ,also make sure you are getting spark cappymd1
the ignition system got wet
get a hair dryer and turned on set it so it blows on the engine side where the spark plug wires go into the engine
let sit on for 1 hour, try to start
