Well it's back, and because I am a worry wart. The new ECU, stand bracket and valve gear I expected there to be things not working or faults. Not at all, everything is fine it's running like a dream and just returned from a 100 mile run about, it's such a good bike to ride.
I notice that the stand mod bracket is to stop the stand from breaking the stop and folding forward. On closer examination I wonder if it could be utilised
to padlock the main stand in the down position, that may be a good anti-theft device, as long as you don't forget.
