I didn't replace the rear bodywork in case I had to get the sprag clutch out so Ruby looks a bit strange today. It was after dark by the time I was able to do this the images in these videos are poor. But it is the sound that counts here.
The second video shows the engine hot, water temp at about one third of the range and oil temp just over 70 degrees. Again, the starter spins really well and ignition is great. So I'm confident I've solved my problem and can get out on the road again.
