The headlamp needed adjusting apparently, which the boys did for me, also they advised I check the back brake as the pedal seemed to be running out of travel before the brake was fully engaged.
I did the same adjustment to the back that I did a while ago to the front and adjusted the actuation lever on its spline, then whizzed up the road, gave the pedal a good jab and locked the back wheel.

I'd say that was sorted then.

Oh and the baby oil thing worked great on the seat, it feels positively sofa like now.... well, less like a plank, and more like a motorcycle saddle.
