some thing to check on these old girls,
the resistance between the ignition switch tumblers and the key,, during a ride with Ev I found there was none,, none at all in the on possy, where a bump of any size may "kick it out" with very little in the off which doesn't matter I suppose,
just sheer luck they landed where they did, considering I needed it for fuel in 20 klm, and was nearly 100 klm from home
a small plastic clip of some sort will be bought to fasten it to the bike
