Exclamation 125cc Lifan chopper project.

Well I just got myself a new project/headache. So its a 2-stroke chopper with lots of plastic crap on it. But all that stuff will be coming off the bike, and I'm dropping in a Lifan 125cc engine. I already bought the engine just waiting for it to arrive, it come in a kit with:

26mm MIKUNI carburetor
40 mm Air filter
Kick start
Shift lever
Throttle cable
Clutch cable
Clutch lever perch
Engine Cover
Engine wiring harness
24mm Intake Manifold
Seal gasket and necessary nuts and bolts.
Brake lever
Ignition coil
Basic wiring diagram

But I'm stuck looking for the correct main wiring harness. Now the seller did say and so the others that the harness from CT70, CL70 mini trail bikes will fit the engine (Basic plug and Go thing). But the thing is that the engine is a kick start and not a electric start. Does it really matter?? And another issue is that which wire to which do I connect. So all I'm asking for a bit of help with electrical wiring (if possible pictures would be awesome). Now I'm not a electrician so wiring diagrams is like a new language to me. So pictures would be a great way to show me and help others to understand the basic wiring form the engine to the harness. But other than that I thank you all for the great help, and hoping for the best to finish this project with success.

Re: 125cc Lifan chopper project.

I really dont think you can make it higher, but I will be installing 2 small shocks to the seat making it sit bit more higher same time having a really smooth ride. Also did you finish the wiring part if you did can you please take some pics of all connections and such. I dont want to mess us the wiring part and burn everything to hell ))))

Re: 125cc Lifan chopper project.

Easiest way I found was to add about 1" to the shock mount on the swing arm. I used 2 pieces of 1/4" plate, and drilled them for the shock bolt, then welded them to the swing arm, but I wouldn't go much more than 1" higher.
Duhh I didn't look close at your bike it is a hard tail, you could make a plate that sets under your current axle plate, that will make your axle be lower.
