MrDavo:
i decided to order a battery, then I can start connecting things up one at a time. I went for one of those yellow gel ones, I have one on the Harley, no problems there. I also ordered a pair of new spark plugs, the old ones look fine but its one less thing to worry about. They were all of three and a half quid for the pair, posted. How can they make them for that little? I'll still need to know about that other wire from the loom, James.
The first thing I need to do is sort out an earthing strap for the bars, which are rubber mounted, I need an earth for the starter and horn buttons. I think it goes from a tag on the bottom of the bar mount to a bullet connector at the speedo bracket.
While I was in the garage I static timed it, I couldn't get the points to close at all at first, until I tried rotating the engine one full turn, not a wasted spark like on the 750. Thinking about it, the 750 points are on the crank, the 450 exhaust cam runs at half speed.
Before the carb bits arrive I can get the starter and sparks working, hopefully (I already tried the starter to get oil pressure when the engine was on the bench). As I may be in a position to try and start her up once I have rebuilt and fitted the carbs, I decided to check if the petcock was working OK, I had previously bought a genuine set of all the rubber parts and a new screen from Silvers.
Good job I checked, it was just a little bit blocked up!
I dont know what all the grey stuff was, either someone had tried to run the bike on mud, or its just what happens if you leave alloy in contact with old petrol for a decade or two. Much poking about with a long thin electrical screwdriver was needed, but I eventually dug it all out and cleared all the holes and pipe. I also had to clear out the U shaped slot on the tap, which was invisible to start with.
I finally got it so I could blow through the tap in main and reserve, and cleaned the body and face plate up as best as I could. Not as pretty as a new one, but another original 1969 part saved from the scrap bin.
Andrew-S:
The grey stuff is likely to be ethanol/old petrol residue. I recently rebuilt the SU carbs on my Triumph TR3A and found a grey silt in the bottom of the float bowls - when this dried out it turned to a very fine dust/sand, or maybe it was alloy from the inside of the carbs...... :o

Dave,
I did manage to get to the bikes earlier this week - but the light in my storage unit is crap and to be honest it’s going to require me to tear into one of the bikes to trace back wiring and see where they go. At the moment I can’t really spend a load of time tearing into either bike.
But, I did snap pics of both in the battery area - do you have an owners manual??
I’ve photographed the wiring diagram from mine here..happy to email you a high res. picture...

JamesH:
On my red bike, there’s a green wire going to the loom (in addition to the main earth cable).
I think it’s the same on the blue bike.
Wiring diagram suggests the same.
Hope that helps..
James
JamesH:
Picture in owners manual confirms the presence of a second wire from -ve terminal
