Thanks Brian that's a really useful link. Searching for connectors is a real pain. I miss Maplin's, my wife doesn't I was always dragging her in there.

Having reconnected all of the handlebar switch wiring I connected the battery and everything is now working, including the kill switch and horn. Gave the bike a short engine run and all good. Still issues with carbs 2 and 3 with a small dribble from the bleed screws. No leaks from the overflow pipes today. Having procrastinated over buying a compression tester I bit the bullet today only to find it reduced by £5 so that was a result. It is one recommended to me by a member, it's from M&P. As I'm now waiting for the compression tester my next job will be to remove the carbs and have a look and see if I can fix the leaking bleed screws.

Tested the compression's cold and have 100, 90, 105, 110. Carbs off and O ring set ordered. 1 bleed screw had no O ring, 1 was split and the other 2 OK but hardened. Main jet O rings also in poor condition. Float bowls were reasonably clean but the O rings very flat and there are remnants of some sort of red sealant. I'm cleaning the brass ware and lower bodies up the old fashioned way with carb cleaner and elbow grease, I'm not splitting the carbs at this point. Float heights are currently 21.4, 21.0, 23.6, 20.0. Haynes manual says 22 but I'm sure I've read 21 in this forum so I'll double check on reassembly. Main jets have the number 72 on them, Haynes says 75, not that I'm going to change them as I intend keeping all the brass ware provided it looks OK. Still have some more brass ware to take out.
Nurse Julie:
21mm Steve for the 400/4 carb floats. (I've just edited that, I initially typed 22mm in error, now I've put me glasses on and I can see what I'm typing, I've changed it to 21mm 😁😁😁😁)
