China Motor Wiring Info
Q: Which ring is the top ring in the 88cc or 114cc big bore kit?
A:The silver colored ring goes on top, the matte gray goes in the middle. The letter on the rings face up.
Q: What should I set the valve lash/gap at on my 88cc or 114cc race head?
A: You should set it with the motor at top dead center on the compression stroke. The gap should be .003-.004
Q: Do I have to run a battery when I have a LED light?
A: Yes. LED lights usually require 9-16volts DC current. The stator output is AC current and goes very high at high rpm. You will also need a regulator/rectifier to charge the battery. You will damage/ruin your LED light if you try to run it directly!
Q: My new TRX70 stator kit has two yellow wires, or a yellow and a white wire. What do these hook to?
A: If your new TRX70 stator kit has these wires, don't worry, you wont need them to operate the bike. These are additional outputs to charge a battery and/or run lights.
Q: What is the green/red wire for in my stock ATC70/TRX70 stator? There isn't one in the new kit I just bought.
A: The green/red wire comes wired on most Honda motors and is for a neutral indicator light. It is not needed on the ATC70/TRX70.
Q:What is the steel hose that came off my stock TRX90 cylinder.
A: The hose bolted to the side of the cylinder is for an egr valve for exhaust emissions. When installing a 114cc big bore, you can just remove all of the components of the system. If you are installing only a 114cc cylinder however and keeping the stock head, you will have to fill in the small exhaust hole that is in the head. It feeds exhaust from the exhaust port, through the cylinder and out through the vent tube. JB Weld or similar product will work. If you dont fill this in the hot exhaust gas will burn through the head gasket and cause problems.
