little hole on cylinder head?? what for

ok ive noticed for some time and all but whats the little hole about 4 mm in diameter on the right side of the cyilnder head (right side of the bike) just curious why its there :)

It's for drainage of the spark plug well. If any water gets in the well from water crossings or washing the bike it will dain out there. I will also flush it with wd40 and compressed air before removing the plug.

Smoke :)

ohhhh that makes perfect sense now thanks :)

That's how Bruce gets to Wayne Manor from the Spark Plug cave.

i put my air nozzle in there to pop my spark plug cap off.
