Those bikes came and went fairly quickly here on Chinariders. A blast from the past, thanks for the memories, lol. The problem with them, and why they were a blast from the past, from what I recall is they had a vague fatal flaw. The problem was, this site was barely a year old, and none of the bikes were sorted out, and if a bike was known to have 'issues' it went away. The last member I recall with the bike was someone from L.A. (they were CARB legal) who bought it for a low price. I don't recall the issue, but he stopped posting meaning he probably got rid of the few hundred dollar bike.

I am writing this not to discourage you, but because these bikes were a relative flash in the pan even for a group like this, so information will be hard to come by. I have no idea how to use it, but many members have used Taobao to search for obscure parts. CSC is not a subsidiary of Zongshen, but they do sell a few of Zongshen's rebadged bikes, so perhaps could help you with their direct connections to Zongshen. Joe Berk used to work for CSC and retired, but he had personal contacts with Zongshen as he used to go to the factory quite a lot; he has an online presence and wrote a book about riding the Zongshen/CSC RX3 on a long ride, so you should be able to track him down. 'Exhaust Notes' is a blog he contributes to, so see if you can track him down.
