These jets are the correct ones for all PWK /Koso carburetors from 21mm to 28mm. To set up the carb you usually start with an overlarge mainjet. This will cause the engine to missfire (fourstroke) on full throttle. You then gradually decrease the mainjet in size (in steps of 5) untill the engine starts running properly. Be careful: too small a mainjet will result in a lean mixture and piston seizures.
