Hi "Lizard", and welcome to the Forum!
Where in Asia are you? There are several options for the HRC jet kit, and loads of tuning options! Close to 65hp is easily available without getting in too deep on an MC21.
I reckon there is certainly something more in carb setup if you are currently running below 60hp.
