Hole in left side of frame?

[DOKONALY]

is there supposed to be a hole in the left side of the frame, right by the coolant reservoir, its about the diameter a self-tapping screw would leave, I only ask because doesn't the oil sit in the frame? I dont want water/dirt to get in there.

Oil is only held in the frame tube at the front, from just below the steering head to the bottom where the next section of frame cradle tubing welds on,, or  where the oil hose is.

 

And yes the hole on the rear facing part of the left hand frame cradle tube by the coolant overflow tank is normal.

Oil is only in the front down tube, the hole above the reservoir is for a oem wire harness cable tie.

There are a few holes like that around the frame, especially at the rear and underside.  I think its to allow the frame to drain in cases when water gets inside.  Oil is only held in the front portion of the frame (down tube & gusseted area between top/down tubes).
