    Hello everyone, new to the forum and posting for the first time. I am restoring/rebuilding a 1973 Honda CL70. I like others in this forum bought a Lifan 125cc replacement engine. It came with the engine, carb, cdi wiring, cdi, and rev box. well i installed the engine and cdi, but wiring is where im a bit stuck. The wiring i recieved with the engine has the pin connectors but all of my stock harness uses only bullet connectors. do i have to make my own? or can i buy a converter? Also does anyone know what the wire colors coming from engine repesent? Im also stuck beccause i can find plenty of CT conversion diagrams but no CL. I will post pictures later today.

    Thanks for any advice and help.

    welcome to the site bro.
    Isn`t your bike a 6v? If so you will need to upgrade the electrical with 12v stuff.As for the wiring,I am not sure if they make a after market plug you can add to your bikes stock wiring to plug into the lifan,you will prob. need to cut the plug off the motor and wire and tape all the wires.I am sure someone here knows the wiring colors to match up.
    The '73 ct70 had different color wires than the '73 cl70's?

    I'm not 100% sure if the CL70 is similar to the CT70's wiring, but in any case, here's a good reference for what's involved.

    If you have a 12V CDI on your engine, it's fairly simple to modify your bike to accept 12V, as all you need is to install a new 6V regulator (once you've got your wires from the engine hooked up to the bike). OR, you can use the full 12V on your bike if you install a 12V regulator and change the battery and lights. If you need to, you can just swap the engine's wiring harness with that from Dr. ATV's, which just plugs into the stock wiring connectors on your bike, as well as the wires from your stator.

    I have the cdi and rev box and stuff, but do i have to make custom pin clips then? I will try to get my wiring diagram copied so i can show you it. To also let you guys know its a kickstart and the bike is origionally kickstart. What does the bikes wiring comprise of besides coil, rectifier, switches, harness, battery, Cdi? because i have all of the wiring that goes to switches and lights but no rectifier. Thanks again for all of the help.

    Why do you have the pictures posted in a mirror image? That screwed me up until I realized I was actually looking at the left side of the bike, and not the right as posted...:D

    :confused: does the CT70 have anything different besides speedo, headlight, horn, turn signals(front and rear), Signal switch, brake light switchl? cause thats all my bike has and was wondering if a CT70 harness would work on it. anyone know where i can get a harness for my bike.

    That's probably for the best. Unless you're replacing a main switch control assembly as part of the process, modifying an existing harness will require less work and the results will be cleaner. With a harness from another model bike, you take on the added chore of lengthening/shortening leads to fit your machine.

    Those easy questions from having no expierence.

    i now have a better understanding of the wiring. I was wondering, i know that the green/red wire coming from my engine is the neutral wire. Is this the wire that plugs into the light in my speedo? What should i be looking for to plug it into? Can my old rectifier convert my lifan's power to work with stock lights? If i need to replace rectifier, do i need anything else to replace like horn, bulbs, any relays? Thanks for all of the help.

    Yes, the neutral wire connects to the neutral lamp in the speedo. You can just connect the green/red coming out of the new engine (assuming it has one) to the green/red on the stock harness.

    You'll need to replace all your lightbulbs with 12v bulbs, and replace the turn signal flasher with a 12v version. Don't worry, it'll all cost about $10 total.

    And no, you can't use your original rectifier. Use the one that came with the engine and connect the red wire to your battery. Dr. ATV sells the four-wire connector for Lifan rectifiers, or you can just use spade terminals.

    I just did this conversion to a C70--different wiring system, but some of the same concerns.

    I'm thinking of converting my CL70 too--did your stock footpegs bolt onto the new engine? What did you do about the throttle cable?
