Take the plug out, drain the carb, fuel tap off, kick it over a dozen times, take the exhaust off or get the bike vertical to drain any fuel in there out.
Then leave the bike over night to dry out (spark plug still out) - quick way is to use a hairdryers or equivalent, get some heat in there to evapourate the excess.
In the mean time, get yourself 2 new spark plugs, that plug will be pretty much dead. Next day or after hairdryer, new plug in, exhaust on, fuel tap on, kick it over, shud fire up after a few
