As for jetting... there is not one universal answer for your bike. Think of your bike as a birthday cake... Jetting is like lighting the candles; the very last thing that you do. Carb rebuild, sync, standard tune up (cam chain, valves, ignition timing) must all be done first. Only then can we start to tackle the jetting question. Some quick tips on jetting tips.
The main jet has an effect on the top 1/3 of the rpm band (6000 to 9000 RPM). The bike should pull strong from idle to 9k without any issue. If it revs hard then hits a wall, say at 7k, then you are too lean. This can be verified by checking the color of the tips of your spark plugs. They will be fairly clean and almost white. If the bike pulls to about the same rpm but has trouble doing it then it is rich. If you put the choke on 1/2 way you will get the same effect. Spark plug tips will be black and sooty. Ideally the plug tips should be tan in color for a proper mixture and the bike should pull to top RPM smoothly.
