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