So, here's what I came up with for lowering the gauges/headlight with the Cycle Cat triple.
I used three different OEM fasteners: (1) the two special screws (Allen fasteners that secure the gauges), (2) the two metal fasteners with M5 threaded rod protruding from each side, and (3) the two hexagonal fasteners with a pin on one end (that fits into the plastic inserts that are pressed into the U-tube) and an M5 threaded hole on the other.
First, I used a utility knife to carve a little material from the area where the gauges rest against the bottom of the triple. This allows the gauges to sit flush against the bottom of the triple. In these two pictures, you can see where I cut material away.
Instead of the OEM plastic plugs that insert into the U-tubes, I used some stiff rubber tubing, shown on the pins above. This allows the whole thing to be disassembled easily, provides damping, and is nevertheless sturdy when assembled.
Here is the U-tube after welding and powdercoating:
Then I drilled 3/8" holes for M6 rivnuts (rivnuts will obviate nuts for securing the screen):
Rivnuts inserted:
Now some polishing:
With the pieces of rubber tubing inserted into the U-tube, I put a little grease on pins which are attached to the fasteners holding the guages onto the triple, and pushed upward to secure the U-tube:
The rubber fittings allow the U-tube to be removed easily. First, remove the two bolts from the lower triple clamp, and then pull the U-tube outward and downward.
Here you can see how an Allen bolt (and wavy washer) is used to secure the windscreen to the brackets on the U-tube. No more difficult-to-reach nuts on the inside of the bracket.
Here's a shot from the side with everything bolted up:
And a shot of the cockpit:
If nothing else, this mod cleans up the area around the top triple. I also added (temporarily) an Al "dash" to hide the wires behind the headlight.
