I went over to Francisco's this weekend to help on his BSA A10 and his '57 Thunderbird. The Thunderbird isn't firing. Looks like it's the coil and electronic ignition box. It was just the coil but I helped fry the box by switching wires around. Stupid positive ground. The A10 is badly wet sumping. We figured the oil pump was failing, so we pulled that off. The gasket looked pretty roasty toasty. The worm gear pump on the BSA seems so much more complicated than the plunger style on a Triumph.
