I have recently been given a pull start 2 stroke 49cc Chinese pocket bike (brand unknown).
Whilst I have reasonable mechanical skills with motorcycle engines, my electrical skills are pathetic. Sick

This bike was given to me with most of the wiring removed, whilst I have most the wiring, I have no intention of using it all.
I have removed battery, all lights, speedo, tacho,key etc.
I wish to use just a basic wiring setup (with killswitch) to run and stop the bike without the use of a battery.
Can anyone offer some advice as to what would need to be wired to what?

What it appears to have at the moment is a red wire coming from a generator? plate on rhs of crank. A black and a black with white trace from the crank reading coil(to kill button I assume). 3 wires coming from a aluminium box under the tank(voltage regulator i think), 1 red, 1 black and 1 grey.

Can anyone shed some light on this subject for me?

If you are not using a battery you should get rid of the regulator. There will be a wire coming from near the flywheel with a tracer on it that goes to the coil. One from the coil to the cut out. The rest are irrelevant. I would completely remove the charging and lighting system as it's just dead weight.
