Thread: Man I'm confused... 140cc clone

Without boring you to death with details here's the skinny.

I ordered a GPX140 motor from TBolt USA which came to me as a PitsterPro 140 that says ZS on the box (for Zongshen I assume). The rear motor mount is too wide but the top one fits fine. Isn't that a problem with YX motors, not Zongshen?

People with YX motors; did you grind away at the cases or the motor mount? It looks like the swingarm won't interfere, but I guess I won't really know til after the motor's in.

Wiring the YX: my connector came crushed, but I'm not really that upset. The problem I have is I've got 6 wires coming out of the motor; a stand alone green (chassis ground I believe) and 5 going to the connector: blue/white, green, something else, and TWO YELLOWS (?!?). Not a yellow and a yellow w/ red strip; two yellows. Anyone know what to do here?

Thanks

i ordered the same engine a few weeks ago. i put it in my frame with 0 problems. (1970 h)

A photo will end all doubts on this one

You might have to pull your motor mounts apart slightly to get the engine to fit. I have seen this in the past even using stock engines

I used a piece of threaded rod and worked 2 nuts back on forth on each side to open the mount ears up a little. They usually do not have to move very much

Ask the supplier for the wiring diagram, they should point you in the right direction

either yellow will do.tape up the other.
