My partner's lad has just passed his CBT. I was utterly gobsmacked that they passed him, as when out on the road he went around a roundabout the wrong way. They passed him, and then said he shouldn't go out alone yet because he's "a nightmare". The cynical side of me thinks that they don't want him taking up a half-price repeat CBT slot (as is one of their offers/gurantees) when they can fill full-price slots in the summer months.
Anyway, me and him rode the scooter around fora bit and it's still seriously down on power. It wouldn't even get up the moderate but long hill that he needs to go up to his dad's house. So it's back in the garage. The guy there is very good, he's going to fit a new caliper and brake assembly (as for chinese parts it's cheaper than rebuilding stuff), front brake was binding a bit so maybe that'll help. Also it felt like it wasn't revving out properly, and would often cut out when throttle was shut off quickly, so new carb (£30). Finally he's going to flush the fuel tank and fill it with super (i.e. not E10); he did suggest that from the start but I couldn't find any in the area I was at at the time I needed to fill up.
Failing that, we'll just have to sell it and get a new one. The ones he used on CBT went up hills with no trouble, albeit slowly, but this one comes to a halt at full throttle up any decent hill
