After swapping the loom out.

there are the main 20amp fuse down by one of the side panels near the seat, i cannot recall what side of the bike it is?

it could also be the starter switch? I have done big jobs before only to have something else fail (side stand switch) half way though, un known untill I had ripped the bike to pieces again.

You talking about the one in the starter relay... the 30 amp ones, there fine else I would have no dash lights.

yup thats true

have you rocked the bike back and forwards in gear and then try to start again, to see if the starter is dodgy?

Missed that bit in the original post.

I think its just going to be strip it down and have a look again...

One thing though... from the connections to the carb heater there are 2 more connections below there. Just single lines. I think one is the oil pressure switch, and the other I can't remember or be sure if I have them round the right way... Anyone able to advise?

check if one of the connections are for the timing pickup sensor

Definitely not the immobiliser from the Meta alarm... Wouldn't be able to turn it over if it was.
I've got a loose connection somewhere on my bike, which sometimes causes erratic backfires and then not being able to start it. Try wiggling the wires going into the ignition unit under the pillion seat, that seems to fix it for me. That might give you an idea to which is loose (if indeed it is a loose connection).

Have you got a spark at the front?

I need to take the front apart to check that so never did, it was easier to check the back. Though if I had a spark at the front it should run, as I've had it running on one cylinder before.
