Hello,
I don't beleive it
After all the messing about trying to start the Buddah it turns out on later investigation the power supply to the coil had come unatached

.
This would not have been easily recognisable as the coil is tucked away under a thick rubber cover, this may have easily happened while leaning over the engine to bleed the clutch cylinder.
A couple of pull ties soon sorted that problem from happening again.

:
Now the Buddah is very happy and full of life starting every time first time on the button.
Looking on the bright side the weekend was not a complete waste of time as lessons were learnt and preventative maintenance carried out.

.
Mike.
