It appears to me the only ability to adjust the gap on an Alton install,
shown above as 0.090", would be the ability to move the pre installed shaft hub.
This Alton shaft hub does not appear to be movable.
So the "gap" is fixed gap for each Vincent twin install.
So this 0.090" gap must be pretty standard fare for Vincent twin.
