Welcome to the forum.
I believe we are the only Zong Sportbike owners, and mine is in pieces all over the shop waiting for parts I hope will fix it.
I don't know the answer to your question. Best bet would be to look at the numbers on the jet with a magnifying glass.
You may get some info off this particular Zong site:
