Oh boy
This was a most-enlightening video, using the boards as bead breakers, as was the "adjustable" 2x4 framework against the wall in tat manner - simply genius. I've changed hundreds of tires, and being able to use your knees to keep the tire bead in the valley is key. Worst part for me is always feeding the valve stem through the rim. Ouch! Don't like working on the ground though.

One thing though. The point he made about the red (or yellow, or white) dot/circle) was that it is the heavy spot on the tire (not true), and must always aligned next to the valve stem to compensate for the weight of the metal removed where the valve stem hole is drilled.
He is correct in that it should be aligned there, but not because it is the heavy spot. It is actually the spot that is 180 degrees across from the heaviest spot, although it it is usually referred to as the lightest spot (splittin' hairs here).
But I wondered if there was any validity to his assertion about removed metal, so, just for fun, I weighed some stuff, with results in the pic below. In the lower right scale is a trio of 1943 steel pennies, any one of which is larger and thicker than the hole in a steel rim.

The solution was very simple; i knew something was wrong but everything looked in place, except....
The wheel ROTATION was backwards so the pads were bedded in on the disks but now did not match the pattern of wear.
Simple but interesting effect, once the wheel was turned around everything was fine as usual.
Dave i just use 3 large 600 mm. tyre irons, you can see them in the middle picture and plastic rim protectors in between the rim.
With the cable ties on the tire and lube on the working surfaces it was easy to get the tire back on the rim, once on you just remove the cable ties with a stanley knife to move the locking tabs back to unlock the ties and re-use them next time, place the tire so there is no force on the tire and inflate until the beads set.
I use a 5 liter garden pressure weed sprayer ( the orange thing in the last picture ) and a clear plastic hose that just fits the sprayer and the valve, i clamp the hose, pump up the pressure in the tank and release the clamp to quickly get the pressure inside the tire and it seats on the rim, done the same thing last time with a co2 cartridge, same effect.
Max, trying to think about this without overthinking it, but going to anyway. Aside from different width axle spacers, there is another anomaly. The wheels for ABS and non-ABS 2013 models are different, most likely because the ABS model has a flat steel pulsar ring bolted under the right disc.
So it's possible the disc on the right is not supposed to be perfectly centered on one model or the other, compared to the left side. We're talking 2mm
The ABS model also has a different right-side caliper and fork leg, so any alignment issue could be taken up in a variety of ways.
Anyway, it's corrected and not an issue.
