I have an xvalve I'm gonna have tapped so it can be aired on the reverse(left) side instead of the standard(right) side. But there is a tiny hole right in line with where the new threads will end up. I'm not sure what it is for(possibly a bleed off or something?), it doesn't appear to have any real function. The new thread will actually cut right down the center of this hole.
Any tips on this? Has anyone else tried doing this sort of mod before cause I don't see anything like it on the forums in my searches. Any help would be greatly appreciated so I can get this project done asap.
