For what it's worth, my advice is to get it running well as standard, first.
You can get a specific ignition kit for Bantams called a "Rooster Booster" but there's not much wrong with the original points and coil system, except that it's 40+ years old and might need some attention. 
12 volt ignition "Converters" bring their own problems if you're still using the original generator.
6 volt halogen headlamp bulb is cheaper and easier to fit.
Please remember how many "unfinished projects" on Ebay etc. have been started and then the owner finds that he is out of his depth.
I'm not a "keep it standard at all costs" kind of person, but at least standard bikes have manuals to help explain exactly what goes where.

OK, thanks for that.
If anybody wants to know, it's a coil ignition Bantam.
Does a coil ignition Bantam have direct lighting, I know the stop lamp works when the engine isn't on but it's not the same with the front light, in this case, will the light be a bit dim?

The lighting should work off the battery on a D7 .......... If in doubt check wiring diagrams. Before doing anything I suggest you buy a Haynes manual if you don't have one then have a good look at it before doing anything.
Good luck

I do have a Haynes manual but it's in South Wales with the bike, does this mean that the front light just isn't working?
Or perhaps it does run off the battery but just when the engine is running?

Problem with electrics is Lewys matey is that without actually being there with a few testers and seeing what the problem is it is very difficult to diagnose a problem. Yes it could be the bulb, it could also be the switch, or a bad earth, or a bad wire. As I said before you just got to follow the yellow brick road. Start with the obvious, then step by step eliminate all the possibilities until you find the problem. I bet when the time comes your grandad will be able to help on this if he has been into bikes for a long time. Sorry I can't be more specific but without seeing the problem a diagnosis is difficult.

Surely you can download a wiring diagram for your Bantam from the net?
And probably loads of other stuff that will help you understand what goes where on your bike and how it works?
Than you will be better prepared when you get to your bike.

Here's the wiring diagram for a Coil Ignition D7 Bantam:

I can't see the wiring diagram but it really doesn't matter.
I meant that you could be studying the wiring - and other bits - even when you are away from your bike so that you are better prepared for your limited time when you can work on it.

Does anybody know how much to expect re chroming the bike to cost?
I think I might do it if I have a bit of cash once it's running.

For all the chrome bits on the whole bike? Easily £500.

Sorry, I didn't explain properly, I meant just the tank, like this:

Ah right, More than likley cheaper to get a second hand tank off ebay, I would of thought around the £100-£150 mark to rechrome that tank.
Assuming it doesn't have any dints that have be filled, if it does then it can't really be re chromed.

OK, thanks for that, I think I'll be able to afford that and I really think it's worth making the bike look nice.

Dead boring, but get the wiring fixed and the basic bike running well first.
A tatty tank willl not leave you stranded at the side of the road; many other problems will do so.

I know that I'll need to do that, but as it'll be a while until I can even start working on the bike I'll need to sort out what I need/want to do and how much it will cost.
Of course, the workings of the bike itself always take priority.

Good luck
After consulting a Road Test of the BSA Bantam D7 De Luxe (the version I have) from 'Motor Cycle' 24th June, 1965, it says:
"This particular version of the Bantam Super has those unusual Wipac electrics in which the current for the head-lamp is direct-supply, while everything else, including ignition, is fed by way of the battery"
So I can assume that this is the case of mine, as I've already done a check on the electrics and they seem to work fine.
Does anybody else here have a 1966 D7 De Luxe that I can compare it to?
