Hi, when you left the bike uncovered was it on the side stand?, if the drain holes on the cylinder head are blocked water can lay in the spark plug holes causing a misfire, dry & clean around the plugs use compressed air through the drain holes & around plugs,don't wont any crap dropping down the holes if you remove them also check plug caps are dry to. You can always switch plugs around to see if problem moves to another cylinder,a failing spark plug would be wet with petrol.
