Exhaust emissions are controlled by the
design of the fundamental engine
parameters and components
(e.g. carburetion, ignition, timing and
valve or port timing) without the addition
of any major hardware.
The carburetor is set at the factory to
provide an optimum fuel-air mixture
under all operating conditions.
It enables your machine to run smoothly,
be fuel efficient, operate reliably and
produce low emissions.
