How do I make my Zongshen 200cc Pit Bike go faster, without NO2 or a big bore kit?

Should I try different sprockets?

please help!

Honestly, I doubt that you will find much for that bike. That is one big disadvantage to buying a Chinese bike. I know this isn't the answer you're looking for, but if you really want to go faster you should sell it and get an actual race bike. A 125 MX bike would run circles around it plus handle much better, have better suspension, lighter weight and easy to find replacement and performance parts for. Sprockets aren't really going to help unless you are going for the Zongshen world speed record at the Salt Flats. When you gear higher you will get some top speed but loose acceleration and vice versa.

Its a pit bike.

Why do you want it to go any faster ?

i race and also own a chinese made pit bike. yours is already a bored out version of a 50 so wiyhout modifiying and splitting the cases or port and polishing it yes the best way is to change the sprockets. a smaller (less teeth) will make it go faster.it will cost you a bit of bottom and mid range power but it will wind out longer.
