2002 beta alp 200cc will not crank over with button starter and there is no spark at the spark plug

For the engine to run, it needs spark, fuel and compression. You can check the spark by removing the spark plug and grounding the electrode against the cylinder head. When cranking, you should see the spark across the spark gap. You could also use starting fluid to see if you have a fuel problem. If it starts at all on starter fluid, but then stops, then you probably have fuel problem. A compression tester will tell you if you have a compression problem.

No can't be PATS . PATS on your vehicle disables the starter . Pull a spark plug wire an check for spark , do fuel pressure testing etc...

have you checked the coils on each spark plug to do this take out one plug attach the plug wire back on to the plug and ground the plug to the motor and have some one crank over the motor but do not hold on to the plug or you could get a strong shock

plug, cable, plug cap, coil, pickup coil in the stator.

clean the carb and check spark plug !

Check the starter and the starter solenoid if those are good your starter button may be bad

check your compression. piston rings might be ate up and its time for a rebuild.

could just be a weak starter? maybe time for new brushes. also try jumping the solenoid to see if that helps.
