RV'd with Champ at Oxford Service on the M40, handed over his race refueller and got a spare CB125 engine in exchange. Isn't the Underground Railway great? Fettled the SL125: got the valve clearances set, which made it sound a million times better. Then tracked down an intermittent electrical fault that sometimes killed all the electrics when you used the front brake. Put on the side panel stickers. Dug the 400 Four out of hibernation from under a pile of cardboard boxes. It started instantly, and I took it for a blat and then down to the supermarket for some supplies. God, that's a lovely bike. And Monday I'm off to Brands Hatch for the British Superbikes. This is a *good* weekend.
