All very true points but I already have enough tools to screw things up. Replacing things I am okay. Rebuilding things like brake cylinders, calipers, and carbs I can do. Adjusting brakes, timing, points (maybe), not bad but balancing carbs (especially 4) and valves I am hopeless - electronic stuff too. By the way are the front blinker bulbs suppose to stay on - not flashing but on - when the bike is running?
