Done a bit more out in the cold today.
Removed the water pump and clutch casing off the bike.
But noticed some wear marks around the outside edge of the clutch basket which is a bit concerning. I can also feel some furring on the inside of the cover where it has been rubbing.

The clutch basket feels nice and solid and there is no play (wobble) in it that I can feel, so what may be causing this.
That's how tight tolerances are in there. So running wires for the LED along the inside of the casing towards the back is going to be out of the question. I may have to consider making a hole in the casing towards the outer part of the casing and running the wires along the outside of the casing which wont be as neat. Though I could spray over them so they blend in with the rest of it. Not ideal but LED's may still be possible if I run them as far towards the outer part of the casing as possible.
There is the slight angle on the outside of the pressure plate that leaves a bit of space. I will also have to grind some of the lips down on the inside of the case, just outside where the rubber seal sits, which will give me a bit more. I will have to wait until the LED's turn up and see how deep they are.

I'm also thinking to run them around that part I will either have to cut splits every so often in the strip so it bends around or cut and splice some wires in the strip every so often. The LED strips can be cut every three LED's. A bit of an butt-ache and more work, but if needs be and it makes the job feasible, then so be it.
Put the new cover on to measure clearances for the window.
Yet again more tight clearances but window is not so much of a problem.
I tied my clutch lever back so the clutch was disengaged and I could measure maximum clearances which is 10mm without the rubber seal and quietening device from the outside point where I want the window to run flush like the original. This does not allow for any wear and tear on my clutch plates. I figured I should knock 1mm off to allow for a new clutch kit when it eventually needs it.
The rubber seal and quietening device are 4-5mm depending on how much the seal compresses down once everything is tightened up. So if we say 9mm clearance minus 5 to play on the safe side, that leaves me with fitting a 4mm Lexan window. The bit that protrudes through to make it flush with the front through my cut-outs is 2mm. So I'm looking at recessing part of the window by 2mm which leaves 4mm Lexan on the window areas and 2mm for the rest of it plus the quietening device.
That is probably the route I will take but 4mm Lexan is not much though it is tough stuff. My only other option would be to leave the quieting device off altogether and then I would have more clearance to add another couple of mm.
Why is everything I do such a challenge. Nothing is ever straight forward.
