Electrical fault sorted, bike went for MoT. The very nice bloke noticed the missing nut on the torque arm and put one on, before passing it - proper decent service! On the way home, my novice efforts to solder a throttle cable end on without purchasing a solder pot (I used a radiator end cap and butane torch) came back to haunt me, as the cable pulled through the end

I had to walk alongside the bike in first gear for 3 miles in the rush hour - the walk of shame - that'll teach me

Next day, solderless end went on as the shops were too busy and off I went, only to discover the cheap Chinese petcock was intermittently starving the bike

On the sunny side, the tank looks good and the POR 15 kit has sealed it well thus far. More work is needed on the seat.
