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?
Flaps should be lower down, they're in place to guide water to the drainage holes.

This debate was had many moons ago probably on the yuku site. 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.

I suspect that with the flap forward, airflow will have more effect than gravity and the rain will stream off the sides and spray over the plug caps more than with the flap down. The manual shows the flap positioned down.
Not that either position will have much effect when the bike's on the sidestand.
