- The data presented here, deals with the conversion of light-weight, air-cooled, reed-valved, chain-saw type, two-stroke engines into high-output, competition motors for powering small recreational, sports and organized racing vehicles. Raising the output of small two-stroke engines via the usual methods, entails some problems associated with their high RPM potentials, reed and rotary-valve induction systems, cylinder and piston ports, crankcase induction, anti-friction bearing crank-trains, air-cooling, and fuel-lubricant combustion. Developing their modification routines involved techniques differing considerably from those encountered in boosting the outputs of small four-stroke engines. Some highlights of two decades of such engine conversion which might be of interest to design engineers, will be discussed.
