BUYING A BULLET
Until 1955, ignition and lighting were powered by the ubiquitous Lucas M01 magdyno. Some machines were equipped with the auto-advance Lucas SR1 magneto. Any magneto needs to be healthy for starting, especially when the engine is hot. This is a critical issue to check before purchasing: look for a recent rebuild or it could cost an additional couple of hundred quid.
The original RE manuals provide servicing info for dynamos and regulators and many modern regulators are available, some with 12V options. Similar regulator I rectifiers can be wired in to 6V alternator systems to provide 12V if desired, but there are also some decently bright, low demand 6V bulbs around these days. If the machine has coil and points ignition and is starting cleanly, I would let it be. That way, you won't end up going on line to ask 'I have just fitted electronic ignition to my Bullet and now it won't run .. .'
The Enfield clutch can work very well if assembled and set up correctly.
