The function of the fuel evaporative control system is to
collect and store evaporative emissions from the fuel
tank and engine. A carbon canister that is mounted to
the left side of the frame is used to collect these evapora-
tive emissions. Fuel vapors from the engine and fuel
tank are vented to the canister when the engine is not
running. Vapors from the canister are consumed when
the engine is running.

NOTE: If there is restriction in the canister breather, the
carbon canister or the vacuum check valve, the fuel tank
may distort due to venting issues. If the fuel tank returns
to it's normal shape when the fuel cap is removed, re-
striction in the evaporative control system is likely.
