Ok, this is the definitive answer to adjusting the hand brake.
I have had to strip my scoot right down to bare metal to remove all the water pipes to clean out the oil sludge and found the brake adjusting point.
It is just forward of the right rear foot pedal. Unfortunately, basically all the mid section and seat bucket area must come off.
I will show photos as a picture is like a 1000 words.
Please ignore my advice about taking the front fairing off.
