Motorcycle tank vent cap

My KTM LC4 was missing a breather cap for its gas tank cap.
There was only a nipple resulting in water in the tank and carburetor after washing and perhaps heavy rainfall.
 

As the breather nipple is horizontal, i made a small drain hole to let water drain out should there ever get water inside. Make sure the drain hole is pointing down.

Fits my LC4 LSE/MIL but could fit other models too.
