Kev, your point about the disk rubbing against the caliper might be right.

When fitting the front wheel, I found that it's important to spin the wheel and apply the brakes before the spindle is fully tightened.

IIRC, I'd fit the spindle through the forks and wheel, tighten the pinch bolts on the side where the spindle (wide part) goes through first, (non nut side)then fit caliper, spin the wheel and hit the brakes, this would centralise the disk in the caliper (all being equal). Then drop the bike off the front stand (to ensure there was no force from the stand causing issues) and then tighten the main nut and then tighten the pinch bolts on the nut side.

If that makes any sense?

Bit different to how I do it Tim
Once I have pushed the spindle through as far as I can and tapped it home with the nylon end of my prop stand I then do the 28mm nut as tight as I can until it tries to turn, then nip up the pinch bolts on the right fork soo they grip the shouldered end of the spindle. Then I fully tighen the 28mm nut, tighten the pinch bolts on the left (Speedo side) fork. I then undo the pinch bolts previously nipped up on the right hand side. Fit the caliper, pump the brake lever until the pads can stop the wheel spining.

I then take out the front paddock stand. Then with the front wheel on the deck pull on the front brake and pump the forks up and down so everything aligns itself as the right fork can move along the wider part of the spindle, allowing to finally tighten the right fork pich bolts.
Works a treat providing the Spacer replacing the speedo is the correct width and the spindle is in fact straight

Hmmm, now I remember ensuring there was a ferw mm of the axle poking out from the side of the fork leg (not flush) to get the single disk centered up!! It was only after the pads were very low that I had any issues with proximity to the caliper though.
