Enjoy the aqueduct, Ted. It's quite an 'interesting' perspective if you admire the view from the West facing side, (not the towpath side!). Mike.
Hi Ted, where did you get your plugs from? I had an intermittent fault on my KH 250 which I finally traced down to a sparkplug breaking down, my fault as I bought them off eBay, as soon as I replaced the plug normal service was restored. Although I do appreciate that as it is with 2 cylinders it is unlikely but worth a check.
What plug caps are you using Ted as the screw on top nuts are still on yours and if your using NGK caps they don't tend to have them as they use the threads to grip. A better picture of No1 plug would help to see if it's a cheap copy, look for smudging on the lettering, the top nut should also have a small indent, the crush washer isn't a good copy and tends to come off when pulled down. Also look for machining marks on the metal parts. No1 doesn't look to have fired as it's wet through, which is worrying as you need to find out why it's like that.
