I have been asked about my 6v to 12v conversion. So here is a bit of info on it.

As i am using a motogadget m-unit to run all my lights etc I threw away the old wiring loom and made a fresh new one. This meant that the cabling was able to handle 12volts without any problems.

Next I wired the CDI unit on the bike directly so that the bike could run without a battery.

Keeping the original generator coils I ran the charging lead to a 12 Volt regulator/rectifier and that in turn to a micro antigravity 12Volt battery. Next I fitted LED lights throughout the bike. 

The bike hasn't had a lot of running in the dark with a lot of lights on, but it looks like the original generator will provide enough charge to keep the battery topped up.

Should I find this is not the case I will be able to connect the original light power lead to the headlight, as its currently not in use.

hope that makes sense :-)
