Exhaust emissions are controlled by the
design of the fundamental engine
parameters and components (e.g.
carburation, ignition, timing and valve or
port timing) without the addition of any
major hardware.
The carburetor comes from the factory
with a standard setting.
On this machine it is no longer
necessary to adjust the carburetor.
It has been set at the factory to provide
an optimum fuel-air mixture in all
locations and operating conditions.
