taking off bowls

I believe you can take off the bowls without taking off the carbs.

Another method to try

Make sure the two little holes at the bottom of the master cylinder are clear, a toothpick works well. Considering you have been bleeding the system, they're probably clear already.

Turn the bars...

maybe bits unscrewed and are in the float bowl

It looks like that part, which I think is the needle jet, is held in place by the main jet holder which threads upward into the carb body. Worth looking in there.

1) our rims are too narrow

2) front tires are designed to resist large braking forces in one direction, not acceleration and braking in two directions

possibly steering head bearing

If you put some weight on the seat and loft the front wheel, you can check for play.

Screw the adjustor and lock ring all the way in, then out a bit until the slots in the adjustor and the lock ring are facing forward. With the cable NOT routed through the adjustor, stick the end...

rationale for kickstand switch

The kickstand switch is there to drive the interlock circuitry. If there's no interlock preventing riding with the kickstand down, there's no switch to drive the bulb.

all bikes have a resonance around 45 mph

Did some digging for the Concours, results here:
http://web.ncf.ca/ag136/frontWheelWobble.htm

The solutions are:
1) tighten steering head bearings
2) steering damper
3) put up with it

You'll need some form of adjustor to change the preload.

more damper stuff

Yes, if there was one with exactly 142 mm of stroke. The next size Sprint is 160mm stroke, 460mm overall length, and wouldn't fit under the fairing.

The damping is adjustable, you can see the knob...
