Re: wireing ??

You need a 12V wiring harness, CDI box, and coil to make your engine run. The '79 Z50 is a 6V points-type ignition and the stock wiring and coil will not work with the 12V engine you have in the bike.

Re: wireing ??

The parts wont interchange between the honda and lifan motor. Youll need to make your own wiring harness or get a wiring harness like the one below and modify it:

eBay Motors: Lifan Trail 70 Main Wiring Harness Honda ATC 70 90 110 (item 300286726628 end time Jan-20-09 09:54:57 PST)

And youll need a 12v coil.

Did you happen to overlook that sentence in the above post?

most lifans engines like this one come with the wiring,

eBay Motors: LIFAN 125CC Motor Engine XR50 CRF50 XR 50 70 CRF70 CARB (item 330281425695 end time Jan-22-09 18:14:59 PST)



see thats all that is needed, plus coil [not shown] to make it run on the wiring side.

edit; apparently the coil is pictured.
