The HP ratings come from the factories in China. Disregard all of them, high, low, or in between. Until you put your bike on a dyno, you have no idea what the HP rating for your motor is. These engines are so small that small adjustments like fuel ratio and spark plug gap and ambient air temperature will have dramatic effects on engine power.
When asking for advice, you did not specify whether you wanted only good advice.
