A few days ago when I last wrote the bike it was going really well. Everything felt great. When I started it today it fired ok but I could barely keep it running. It was misfiring and backfiring horrendously. I mused over this for a while and decided to clean and fettle the kill switch. The engine fired and ran absolutely normally - no misfire, no backfire.
The design of these Lucas switches beggars belief. It seems that the switch pad return springs rest against the phosphor bronze contacting leaf, partially fighting against it even before you press it. Over a period of time the leaf will tire and chatter against the contact in the kill postion, thus intermittently cutting the ignition supply volts.
Crikey! What an ill-thought out device! Am I wrong in my assessment here or has anyone else come to the conclusion that these switches are terrible?
