I bought a JIS screwdriver to remove mine; it was easy. I applied a bunch of downward pressure on the screw and gave it a quick twist to break the Loctite. The screws came right out afterwards, no heat or anything. It was harder removing the tank than removing the flies...
After ordering a couple of the JIS screwdrivers, I started work with some trepidation.
I agonized over heating the screws or not, but decided to just try one cold, and see what happend.
I like to fly by the seat of my pants, to live dangerously, if you will.
Anyway, the first screw came out easily, so I kept going, working left to right.
Around screw five, there was some binding after several turns out, probably threadlocker, but the screw turned out with no problem.
The last screw, at the far right, I couldn't get a direct shot at the head, there was some angle.
This one turned out about half way, then bound up, and the head started to strip out.
I turned it back in, and out a few times. I applied a little more force, and .......................
SUCCESS, the screw came all of the way out!
It was a great day to be ME!
It is not a variable length system. It is a fixed length system with two separate throttle plates.
Trying to use one plate to effectively alter the length of the induction tube won't work because as soon as the air is on the near side (nearest to the engine), it will spill around the plate and assume the same velocity as it would have had there been no plates behind it in the first place. Air has inertia but not much and there won't be any tube lengthening effect at low engine speeds. At high engine speeds and under full throttle, there is virtually no difference between having the 'flies installed and wide open and having the 'flies removed.

Helmholtz resonance ?? Maybe someone should ask KHI http://en.wikipedia.org/wiki/Manifold_%28automotive%29#Variable_length_intake_manifold
We Yanks have been known to be a little coarse in our power delivery anyway.
Last night I took the Connie out for the first time since removing the secondaries. Didn't make a big difference in power, but it is considerably smoother with much less herky-jerky at part throttle. Crisper response as well. Shortened pipe and K&N air filter are the only other mods.
