No replies. :-?

Supose most are not familiar with the Zongshen 200cc dual-sport bike.

I have no clue what jet it takes. Type. :-/

I was talking this over with a friend who had the exact same problem (different bike, though) and he advised me that he could not make this mod work successfully until he opened up his exhaust. Could be you've got to much airflow in and not enough out.

Try removing the pilot jet and cleaning it.

Over the last year I've talked to a couple of people with Zongshen street bikes. Apparently the jet/filter mods have made the Zongshens incredibly hard to tune.
The last person I talked to eventually made a Mikuni swap in order to fix the problem.

if it only runs on choke, your idle jet is clogged
