Use a bike cover. You can have it unde the seat.
Drain hole blocked or not blocked it's still going to collect water from being leaned to one side on the stand. The only way around it is to cover the bike or maybe a make some sort of small shield to deflect the rain away from that area.
Maybe some sort of rain deflecting anti gravitational force field around spark plug three In fairness it's not always practical to put a full cover over a bike so a small guard to deflect water away from the spark plugs is a good idea
Park it upside down
There seems to be a rubber flap under the tank that flops / drapes down on top of the spark plugs. I've no idea what it does but was thinking of making something similar, zip tied to the frame and flapped over the right hand side of the engine to prevent it collecting rain.Would that be a good idea, or would it affect the cooling of the engine?

As to whether that flap should be pointing down towards the spark plugs or down the front of the engine. I think down the front of the engine. Surely that's better than guiding water down at the spark plugs.
Keep it on the centre stand when not in use and/or parked for long periods.Make sure the drain holes are kept clear.
the flap should sit on the front rocker cover to prevent water getting into the plug recess under normal riding conditions.
... and this is why a cover doesn't last very long.
