Non one is gonna be able to give you an exact jet size. You need to try it. Start high and come down until you get the correct one. Use the colour of the sprakplug tgo tell you how you are doing as welll as the noise of the engine and the full throttle behaviour.

Rollers could play a part in here as well as the clutch. Do one thing at a time, carb fuirst, clutch and rollers.
