Actually, it will be better for you to probe it and transmit your experience
Do, you can do many things. Can change the injectors and remap ECU , for a few more fuel flow, but you need the engine to breathe better, then you have to change intake for more a larger diameter, but you need to change the compression ratio to burn the most fuel, but the largest compression will cause more load on piston and road bearings and crankshaft, so you will have to make new ones harder. All this will cause more heat, then you need to change cooler system for a larger one, and probably reach 130/140 hp at the same 7500rpm.
But, if you want to reach 150/160 hp, you have to increase the engine rpm to 9000/10000....but this generate vibrations that must be eliminated.
But the clutch was for 112hp and 11 kgm and will begin to slip with the new hp and the rubber joint between final drive a rim, was for 11kgm torque, not for 13/14 kgm, and the rear spokes, rim, the box gear, etc,etc etc
OVER THE YEARS, I LEARNED THAT THE FACTORY ENGINEERS, WERE NOT AS STUPID, AS MY MECHANIC TOLD ME
