ChinaRiders Forums - View Single Post - Zongshen 200GY-2: CDI Diagrams and Compatibility

SpudRider · 08-02-2014, 01:01 PM

The Chinese CDI units have been known to fail, so it is always a good idea to have a spare CDI unit on hand. The spare CDI unit greatly facilitates troubleshooting the bike's electrical system. Also, should your CDI unit begin to falter, you can install the spare CDI unit, and go riding, instead of waiting for a replacement to arrive from China.

It is also important to know the stator and pickup coil will eventually fail for any motorcycle where these units are bathed in engine oil. After many miles of operation the hot engine oil will eventually remove the varnish from the wire coils, resulting in short circuits for either the stator, and/or the pickup coil.

If the spare CDI unit doesn't solve your electrical problems, you should measure the resistance values for the stator and pickup coil, as explained in the following thread.

I recently replaced the stator and pickup coil on my Zongshen 200GY-2. My Zong's fuel mileage has increased, and the engine once again purrs from idle, to wide-open-throttle.

You can purchase the Zongshen stator and pickup coil from Taobao.com.

Incidentally, the Yamaha stators and pickup coils will also fail.

I recently helped my good friend Andy replace the stator and pickup coil in his 2004 Yamaha TT-R225 with Zongshen parts. At that time we also, necessarily, switched his bike over to the Zongshen CDI unit.

The Yamaha replacement parts would have cost over $500.

The Zongshen stator and pickup coil fit perfectly inside his Yamaha stator cover.

We connected the appropriate wires from his wiring harness to the Zongshen parts, and his bike runs great.

Here is the TT-R225 wiring diagram from the Yamaha Service Manual.

If wired properly, the Zongshen stator, pickup coil, and CDI unit will work perfectly in the following Yamaha motorcycles.

XT200
TW200
XT225
TT-R225
TT-R230

I purchased the appropriate wiring harness for the Zongshen CDI unit from eBay. The Zongshen CDI unit employs the same wiring harness as the Lifan 150cc pit bikes.
