Hi everyone thanks for all the brilliant reply's can't thank you enough, actually gone to original pipes keeping the 2 into one for another norton project I've got planned as its a really nice system,
lots to think about there main thing is I'm going to be doing about 15-20k a year on it I know some people might faint at this but promised I'd use it and not leave it parked to the previous owner he commuted on it all the time.
and Using one of the 350 lc's for when the weather is horrendous,
just got to decide best way to go forward
the actual clutch routing thing is there got them to send me a proper pic of it really makes it look a bit weird those pictures, also its got the correct little bump thing just got to track down the bridge stay
guessing I could try and get the primary to seal not tried putting oil in it yet as the previous owner used to lube it before every ride hence the 2 into one but now being back to the twin exhausts,
either stick with the standard clutch an chain primary or check a belt drive system out
want to try keep it looking as stock as possible as I'm head over heels with it looks wise now I've put the tank badges on, was thinking maybe some period ace bars, friend of mine has a 650ss like that.
would love a fontana 4ls on it one day and some sort of trick rear break as I think the hub looks a bit tatty on it, lets the bike down on the rear haha but I'll make do with the commando one thats fitted now 
wow tell you guys what though didn't realise how much the centre stand had actually worn down no wonder my 650ss is always nearly toppling over if I breath on it LOL
