Albert,
I'm glad I found your message. I never check this part of the forum, and I'm not notified if someone posts something here.
Yes, a Zongshen stator/pickup coil will fit perfectly in your TW200. If you purchase or fabricate the correct wiring harness, the Zongshen CDI unit will work with the Zongshen stator/pickup coil.
If you want to communicate further, send me a personal message, since I probably won't notice any conversions you post.
