I always carry a cellphone, whether I'm riding British, Italian, or German. Knock on wood, but I've yet to need to use it. It's just good insurance and helps curb the paranoia. Although you bring up a good point, Debby. If I needed to use it, my luck is I'd be in a no-service area!

Boyer ignition systems can be cantankerous, especially the wire terminations. If so equipped I'd carry some spare wire, connectors and something to join the two together.

Also a multimeter may be helpful.

But my biggest concern is how to fix a flat; it's a breeze with tubeless tires, not so with tubes. Perhaps you could pull the tube part way out of the tire and patch it, but it would be a pain in the ass, especially on the side of the road, at midnight, and in the rain.

The March 1971 edition of Cycle World suggested packing the following parts and tools:
1. Owner’s manual and basic tool kit that came with the motorcycle
2. A pair of vise-grip pliers
3. Wire cutters and spare electrical wire
4. Bailing wire
5. A can of compressed air for tire inflation
6. A valve stem puller, tire pressure gauge and tube repair kit.
7. Tubes of Permatex
8. An emery file and feeler gauges for plugs points and tappets
9. A set of spark plugs
10. A set of points and condenser
11. A spare master link for the drive chain
12. A headlamp and taillight bulb
13. Two fuses
14. A few spare nuts and bolts, 1/2” to 3/8”
15. A throttle and clutch cable
16. An inner tube
