Wiring up a 200cc Chinese motor (163fml)

[killerbanjo]

Hey all. I have a 82 XL 125 RC that I put a 200cc 163fml motor in. I have wired it up so that it run but cannot seem to be able to get the electronics working. I wired up the running circuit myself, then used a cg 125 loom hoping that I could just output the the power into the loom and that it would work... Sadly it does not. Would I be better off just buying a brand new loom or continuing with what I got. I really need to get it working soon though as it without my bike it means taking the bus to work which I hate!

Here is the bike, although I have now painted the wheels and it has lights (not that they work)

Any input would be great!

Just to add, although I could just put a cg 125 lump I have into it, I had to split the cases on this motor just to get it running and put lots of time into it! (first ever case split) So would REALLY like to use this motor, and not the cg lump

Does the stator put out 12 or 6 Volts?
Are your lights 12 or 6 V?

Hey sonic, they both output 12v

Ohh one thing I forgot to mention. I just have a capacitor in place of the battery. But assumed this would not matter as for the last year my CG 125 has had no battery and the only thing that did not work was the horn - it fizzled instead of honked. I just placed a small capacitor there to run the horn for 3-4 seconds at a time.

Also the CG loom is a points loom (not that im using its running circuit)

Okay if they are both 12V you should have the output from the stator (likely 3 white/yellow wires) running into a regulator/rectifier.
From the reg/rect the power should run to the main harness (ie your Capacitor) and then from there to the rest of the bike.
Do you have a wiring diagram for each engine?

Here's what I found for a diagram

From this thread on thumpertalk which should be helpful. Lots of wiring details

I have this one for the 163fml

And this one for the CG

I like how that one has the work "simple" in the URL but it makes my brain hurt just looking at it haha

Gotta go work now, thanks for your help so far man.

Ok from that CG wiring diagram I made a bare essentials ones! And now I can see the problem. The headlight and taillight run right off the alternator BEFORE going through the reg... I hope I have not damaged the reg by trying to pull so much juice off of it! Tomorrow Ill give it another go and see how it goes

Here is the diagram if anyone might find it useful - It took me way to long in ms paint erasing all the unnecessary lines for only me to get use from it haha
