You can find some information on how to adjust the main jet of your carburetor here, Tuning your Carburetor - Idle and Main Jet Circuit Tuning
For a free-flow pipe, main jet 2 sizes bigger, for filter add 1 size bigger, eg 3 sizes bigger on main jet and 1 size for pilot, jets can be obtained from any carburettor shop. Rule of thumb for air screw is 2 to 2.5 turns out, bike must die if jet is turned in all the way, otherwise you have a leak on the inlet rubber. Happy tuning
i made my bike a 177cc and i have a performance pipe on but it doesn't seem to do much. Is there something wrong with my jetting or what is the problem
