Took it out for a nice run today. Went like a train. Was even better than my ride home from the dealer, mainly because I checked the tyres and found the front was at 7psi!
I did notice a very slight weave when I picked it up. It was only on the faster part of the journey, about 2 miles of road, which I (wrongly) put down to the road surface. I went on the same road today, it was straight and true. Glad I checked the pressures. Don't always do that. Last did it about 2 weeks before it went in and it was in for a couple of months, so from 20psi to 7 in 10 to 12 weeks. No sign of any tyre damage. Valve? Will have to watch it carefully.
Anyway, ride was great fun and pleased to have my bike back.
