EVAPORATIVE EMISSION CONTROL SYSTEM
This vehicle is equipped with an EVAP System� Please contact a CFMOTO dealer if the EVAP System has
failed� Do not modify the System, or the System will not meet requirements for environmental regulations�
After disassembly and repair, tube connections should be well connected without air leakage, blocking,
and tubes should be without being squeezed, broken or damaged, etc� Fuel vapors from the fuel tank are
drawn into a carbon tank through an absorption tube� The fuel vapors are absorbed by active carbon in
carbon tank when the engine is stopped� When the engine is running, fuel vapors absorbed in the carbon
tank will flow into the engine combustion chamber and get burned, avoiding environmental pollution by
preventing fuel vapors being discharged directly into the air� Meanwhile, air pressure inside the fuel tank
can be balanced by the absorption tube� If inner pressure of fuel tank is lower than the outside, it can be
balanced through the air tube of the carbon tank and absorption tube� In this context, all tubes should
always remain clear without being blocked or squeezed, etc�, and the anti-toppling valve should be
mounted correctly, otherwise the fuel pump could be damaged, the fuel tank can also become deformed or
broken or other parts may be damaged�
