I've just picked my scooter up after taking it back to Central Scooters to get sorted. They hadn't fixed the grips, which spin on the bars when you twist hard, or put the two missing bolts into the headset.
They had stopped the weird resistance on the from brake lever - apparently the wrong lever had been installed before. They'd also had a stab at fixing the gears, which worked OK at first, but after 7/8 miles home I could shift into third or fourth anymore.
I'm miffed. I suppose I actually have to take it back for a second time and ask them to look at it again.
