yea... guess i should have worded my post better... i meant that i was under the impression the space should be equidistant or non-existant.
Nope, not for the front fork caps. The handle bar mounts are also this way on some bikes, and the bar control mountings employ the same technique. Front side is tightened first and the open space goes toward the rear of the bike.
The master cylinder bar clamp is also the same scheme, except the top is tightened first and the bottom is open.
The teltale is to place the bridge cap on a flat surface and press down on it where the bolt holes are. If pressing down at one end exposes a gap are the other end, the part is milled with an offset and designed to be open at that end after assembly.
