INJECTION SYSTEM Fuel efficiency increase The air-fuel ration can be
adjusted to save fuel The timing of the
introduction of the fuel into the combustion chamber can be manipulated
No need for choke during cold start

INCREASED PRESSURE Increase pressure in the
combustion chamber Can be achieved be
putting a turbine or simple rotating fan

AIR FILTEROpen pod air filter allows better air flow to the engine, increasing the performance

INVASIVE MODIFICATIONMAINJET CHANGES Increase fuel-air ratio needed for alcohol Enlarge this opening by anywhere from 20 to 40%
IDLE ORIFICE CHANGES (Carburator) For the engine to run at slowest, or idle, speeds, the air-fuel mixture will pass
thru the idle orifice If it isn't large enough, will not provide the needed amount of air/fuel blend to
keep the engine running May only be necessary to loosen the idle mixture screw at the base of the
carburetor Can be enlarged by 50%
ENGINE TIMING The correct timing advance for a given engine speed will allow for maximum
cylinder pressure to be achieved at the correct crankshaft angular position
