When I put my Y pipe back on I carefully tapped the copper rings down the pipe a little way using a large socket and they re-sealed very well.  The copper o-rings are available if you want to shell out about $25US apiece.

It's nice when you do something that fixes the problem unexpectedly, and removing the wire was a lot easier than going through the carbs. Kind of weird that the cyl. would cut back in once warmed up.

Half choke and it starts very nicely, just got a few little things to sort out, neutral switch doesn't work, took it out and tested the switch itself and it is buggered, I've got a replacement on order, would like to have another go at getting a really good seal on all the exhaust joints, tried to put the bike through an MOT and they failed it on exhaust leaking from the exhaust stubs at the rear cylinder to the y piece, I did try to rectify it and its better but not perfect, I would like to get hold of a nice condition rear brake pedal, the one on the bike is quite shabby, other than that I think it is pretty well sorted now.

Solved the needle gauges jumping around issue, the carb balance kit had a couple of inline 'taps' used those to limit the vacuum on the gauges, I could then get a sensible reading.

Had a go at syncing the carbs today, used this tool

hooked tubes up to the recommended points shown in the Haynes manual and both guage needles where jumping around so much I could not get a sensible reading, any ideas why this is?

You HAVE to sync or it will never run properly. 
Do a search on $5 manometer if you can't afford the gauges.

If there is a plugged passageway it won't do much good to set the mixture until it is clean and flowing fuel well. It kind of sounds like the rev limiter may have been your problem. If it keeps on starting well I would attribute that to the problem. The jet being plugged and then being fine doesn't have the odds on it's side for that happening.

I have adjusted the mixture but not done the sync yet, although last evening I disconnected the blk/yellow wire going into the TDI and this evening the bike fired up straight away and was firing on both cylinders, maybe coincidence or yesterday it may have had some gunk in the carb which has now cleared itself? also a quick question does anyone here have for sale or know where to buy the carburetor emulsion tubes from?
