To those of you out there who want to move the placement of the hole in the top cap so that it is adjusted properly with the inlet in front of the wick, here is the best way to do it. If you attempt this just be very careful that the electrodes bo back into the holes properly when you re-assemble the Katana. Also, be sure that the Katana is completely assembled with a battery in it and the lock ring engaged. This will prevent you from damaging the short electrode during the re-assembly process. Trust me on this one...
1. Remove the top cap, the electrode screws and the coil and wick. Drain the tank completely while you're here.
2. Replace the top cap so you have something to grip and pull the top of the tank off. It may be a little bit tight so you may have to wiggle it gently to get it to come off. Just be careful as the o-ring reaches the top of the tank, it comes right off at this point and you don't want to smash something as your hand swings around at full speed because you kept puling hard as the top was about to release
3. With the top cap still screwed on, get a fine pointed needle nosed pliers and stick each of the jaws into one of the electrode holes in the top cap from the bottom and simply spin the nylon piece until you see that the air inlet hole pointing straight at the wick hole. The electrode holes should be behind the wick hole so the order front to back will be (1) air inlet hole, (2) wick hole, (3) electrode holes. They should form a "Y" at this point if you look at it from the bottom of the tank top with the air inlet hole facing you.
4. Put some juice on the o-ring from the top cap and a little bit in the electrode holes to help things go back together smoothly.
5. Put it back together now by pushing the tall electrode into it's hole (it should not have needed to be removed from the Katana at any point and should go back on pretty easily without alot of force). As it reaches where the short electrode is, spin it so it lines up and carefully continue to push the tank cover back into place. As the o-ring starts to touch the tank, make sure that it is lined up well and going in evenly to prevent the o-ring from getting pinched.
6. Now just put the wick and coil back in place, fil with juice and enjoy.
I had been seeing a few methods of doing this and figured that I would post how I have been doing it since more people have been wanting to do this and following this procedure will almost completely eliminate any possibility of damaging your Katana in the process.
