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.
