There are 2 sets of serial numbers one set on the motor and one on the frame. The ones on the frame are on the "gooseneck", (where the triple clamps to your forks are connected). The other set on that motor are on the center cases on the top of the engine. As I recall they are just above the left side engine cover.

(1) You will need to adjust the float pin to get the correct amount of fuel in the float chamber of the carburator.
(2) You will also need to set the air-mixture screw , but before you do tht remove the spark plug and see whats the condition of it, is it black , is it brownish, or is it whitish.
If its blackish = means rich too much of fuel, if its browinsh= ok, if its whitish = its too lean.
(3) As for hesitation, check the needle at carbs piston on the accelerator cable, and blow the main jet with high pressure.
(4) Check too the spark plug gap and if its as per the manufacturers specs.
Hope this helps!

Drain and replace the gas with fresh.
Remove the air cleaner and spray carb cleaner into the inlet. Work your throttle a little then put everything back together and try to start it.
