Hello everyone. My first post here. I’m working on a interesting problem with a ‘71 Commando production racer. The bike is very original, one owner, low mileage, never raced. These days it gets ridden 2-3 times a year. In the last few years the bike will start and run fine but come to a dead stop after about 10 miles. It can’t be kick- or bump-started until it sits for 30 minutes or so. Then it starts and runs fine again. This is surely an electrics issue as there’s no fuel starving exhibited when it halts. The bike is well tuned - timing,plugs, air cleaner, etc. After several episodes of this the owner put a Boyer Mk III ignition on the bike. So now it starts more easily but still exhibits the same problem. Before I replace the entire wiring harness or something equally drastic, has this happened to anyone else? 2MC capacitor nor zener diode have ever been replaced but symptoms don’t seem to reflect failures there. Battery is fresh and charging system is working properly. Thanks in advance.
