Sources of Emissions
The combustion process produces carbon monox-
ide and hydrocarbons. Control of hydrocarbons is
very important because under certain conditions,
they react to form photochemical smog when sub-
jected to sunlight. Carbon monoxide does not react
in the same way, but it is toxic. SSR Motorsports
utilizes very exacting carburetor jetting and other
systems to make your pit bike emissions legal and
to reduce carbon monoxide and hydrocarbon emis-
sions.
Noise emission control system
TAMPERING WITH THE NOISE CONTROL SYS-
TEM IS PROHIBITED: Federal law strictly prohibits,
and Canadian provincial laws may prohibit, the
following acts or the causing thereof:
(1) The removal or rendering inoperative by any

(2) The use of the vehicle after such device or

Exhaust Emission Control System
The exhaust emission control system is composed
of precise carburetor jetting and fuel mixture, and
no adjustment should be made except idle speed
adjustment with the throttle stop screw.
The exhaust emission control system is separate
from the crankcase emission control system.
Crankcase Emission Control System
The engine is equipped with a closed crankcase
system to prevent discharging crankcase vapors
into the atmosphere. Blow-by gas is returned to the
combustion chamber through the air cleaner and
the carburetor.
