EVAPORATIVE EMISSIONS CONTROL (CA
MODELS)

GENERAL

Motorcycles sold in some markets are equipped with an
evaporative (EVAP) emissions control system. See

Figure 4-72

The EVAP system functions as follows:

•

The fuel vapor vent tube connected to the vapor valve on
the fuel tank top plate allows fuel vapors in the fuel tank
to be vented to the charcoal canister. If the motorcycle is
tipped, the vapor valve also prevents the loss of gasoline
through the vent tube.

•

Under certain engine conditions, the ECM (working in
conjunction with the EFI system relay) opens the purge
solenoid. Negative pressure (vacuum) draws the fuel
vapors stored in the charcoal canister through the purge

tube to the induction module, where they are burned as
part of the normal combustion process.

Keep evaporative emissions vent lines away from exhaust
and engine. Gasoline is extremely flammable and highly
explosive, which could result in death or serious injury.
(00266a)

NOTE

The EVAP system has been designed to operate with a min-
imum of maintenance. Check that all tubes are correctly routed
and properly connected. Also, verify that the tubes are not
pinched or kinked, and that there is no contact with the engine
parts.
