Iím running a set of cut down fat bob tanks on my WL race bike but I have a problem Iím finally getting around to trying to fix. The tanks use the later model gas caps and the one thatís vented is on the oil side and the non vented is on the gas side. To overcome this problem Iíve made a fairly crude adjustment to a vented cap to make it fit.

I canít seem to find any caps for the left side that are vented so before I buy a new set and drill a small hole in the top of the left one I thought Iíd see if anyone has any other good ideas.
