If I lightly touch the wiring loom coming out of the bottom I can feel very light vibration. To me it sounds and feels like electrical arcing.
Is that a common issue?
Yes, it is. Ignition switch problems are quite common - certainly moreso than ECU trouble - and it could give the symptoms you describe.
What unfazed said about the EXUP servo making a crackling noise is true but that wouldn't cause starting or running issues. The servo lives under the tank and over the top of the motor towards the left side. However, you're confident that the noise and vibration you've detected is coming from the ignition switch or associated wiring, you've probably found the culprit.

Thanks Falcon and Unfazed
Before I started on the ignition switch replacement I though I would check if it was the EXUP servo and lo and behold Unfazed was spot on, I felt like a right chump, still at least I've not ripped out the ignition. I've checked all the wiring and I think after Several days tinkering this has got me beat.
If anyone can recommend a bike mechanic in the Edinburgh area I would be very greatful.
Cheers

Re: Not starting crazy symptoms - Ross - 16-01-17
Firstly thanks to you all for helping out a new owner.
Here's a short update.
I took one of the plugs out to check the spark as a last look before calling in a mechanic, amazingly it fired up on three cylinders and ran. I quickly put the plug back in and it ran on all 4 cylinders all be it sounding very rough. I'm delighted it's running but no further forward. I've started it a few times since and it fired up and ran every time.
Cheers

If the fuel pump isn't priming every (or most) times, I would have a look there.
I should rattle a few times every time the ignition is turned on after it has stood a while.
May be getting a slow gravity fill but not enough to run properly.
