Before doing anything, will the action(s) perform one of the following. An internal combustion engine is an air pump and a device that converts potential thermal energy of liquid fuel into rotating kinetic energy. The more air through the engine per minute, the more complete the combustion is, the more heat retained in the engine to expand combustion residue gases, the more efficiently that pressure that can be used to push longer and harder on that crankshaft throw and reduction of drag will increase power. Bear in mind the two cylinders were designed to reliably and efficiently burn low cost fuels. Large combustion chambers, relatively small/high velocity ports, mild cam timing,large heavy reciprocating parts were designed for lots of torque and limited RPM. Less aircleaner/intake restriction, more cam timing, ports with less obstruction,more efficient fuel vapourization, sparkplug placed in the middle of the combustion chamber, more compression, enough spark energy to light the mixture, free lowing exhaust that uses the kinetic energy of the exhaust to assist cylinder scavaging etc.
