I got it to move by hand with only a little resistance. Sanding the welds was not enough. I widened the tracks slightly by lightly hammering a podger into them.
I reassembled all with a new gear from Ricke(warofman9). The old one was stripped.
Next I refitted to the bike. Powered up and still moving freely between the limit switches.
However, when I put the dash all back together and the windscreen on, it misaligned on first attempt. Stuck again.
I was baffled and left hoping the new gear was not stripped. I did manage to get it working reasonably easy and the gear was not stripped.
Removed cover from motor.

Operated it and could see it was the upper cable not moving. It turned out to be more worn than I thought.

Hand moving the slider up and down, I rotated the cable by 180 degrees with a vice grip.

Retracted the cable, then slowly fed it out bending it hard with a pliers making sure the good side was facing the gear.

When I was finished it sat freely in a circle.

Made sure the sliders lined up again, closed it all up and working perfect once again.
And as Ricke(warofman9) says in his attachment, a clean dog is a good dog. Well I say, a clean cat is still a lazy cat.
