After the recent breakdown, Mike reckoned they might not have tightened up the tappets when they were working on the engine which would explain the pushrod jumping off.
I went for a decent length run with Mark today. At one point the engine cut out completely for about 1 second. Strangely, it had been showing a discharge leading up to that point but the engine fired up again and the ammeter began to show a charge. I'll have to take the seat off to check the wiring (and also in the headlamp) since it felt like an electrical fault.

Pushrod woe
As usual, click any image to zoom in.
I've taken the inspection cover off and you can see the exhaust push-rod seated tightly under the exhaust rocker arm (at the 3 o'clock position).
At the 10 o'clock position the inlet valve's rocker arm has been separated from its push-rod which is now wedged firmly behind the rocker arm's downward facing semicircular nipple.

This
means the inlet valve is jammed open probably resulting in a bent valve stem.
Hope there hasn't been any more damage done.

The engine in my C15 has been rattling and knocking so it was time for it to come out and get checked over.

I've bought a "new" one from Mike Kilvert (who sold Mark his green C15) and with his help got it in and converted it to 12v electronic ignition.
These are pics from when I went down to his place in Wales and wired up the Pazon kit, and a video of trying to fire it up for the first time while holding my iPad!

These are a few pics Mark took today when he came over to see the bike.

Sadly, it lost power with a clunk today after riding A MILE or so from home - wondering if a valve has failed seeing as there is no compression at the moment.
Happily, Mark was with me and he not only rode back to my house, picked up my car and drove back, but I was sneaky enough to walk really slowly so that I'd only covered about 150m before he pulled up next to me and took over pushing duties. The exercise will do him good - no flies on me!
