Installation
1. With the vent tube fittings at the rear and pointing
inboard, start tongue at top charcoal canister into
grooves of bracket.
2. Push charcoal canister toward front of vehicle until legs
on bracket snap down to engage back of tongue.
3. Attach vent tubes to fittings at back of charcoal canister.
For correct assembly, tubes should have been marked to
correlate with stamps on canister, that is, either "CARB"
or "TANK."
4. Attach PCV outlet hose (connection from carburetor
throat and PCV valve) to fitting at front of charcoal canis-
ter.

WARNING
Keep evaporative emissions vent lines away from
exhaust and engine. Gasoline is extremely flammable
and highly explosive, which could result in death or seri-
ous injury. (00266a)
5. Recheck vent tube routing to be sure that hoses are not
pinched or kinked.
6. Insert bolt through battery negative cable (black) into
threaded hole of battery negative (-) terminal. Tighten
bolt to 72-96 in-lbs (8-11 Nm).

HOSE ROUTING
Crankcase Breather/Drain/PCV Outlet
Hose
Crankcase Breather Hose: See
breather hose runs forward from the PCV valve at the top of
the rocker cover through a cable strap loosely installed in two
lateral holes in the front engine mounting bracket (just rear of
the steering head). After passing through the cable strap, the
hose loops rearward following the bottom left side of the
frame backbone, where it is captured in yet another cable
strap loosely installed around the middle of the backbone (the
second of three equally spaced cable straps moving front to
rear). Continuing rearward, the hose passes toward the right
side of the vehicle just in front of the ignition coil where it
mates with a 3-way connector positioned inboard of the car-
buretor.
First 3-Way Connector: The 3-way connector inboard of the
carburetor splits the path of the hose into two directions. The
center barb, pointed at the left side of the vehicle, is attached
to the hose routed to the charcoal canister, while the end barb
is connected to a short hose that jumps to a second 3-way
connector located inboard of the air box.

WARNING
Figure 4-26. The crankcase
Charcoal Canister Hose: The hose to the charcoal canister
is routed from the center barb on the first 3-way connector
back to the left side of the vehicle just behind the ignition coil,
and then downward following the rearward arc created by the
rounded top of the air box. The hose then runs over the top
rear corner of the inner primary housing and enters the loop
formed by the hose connected to the oil drain/return fitting at
the left side of the frame backbone. Passing through this loop,
the hose enters an opening at the front of the passenger foot
peg support where it is then connected to the fitting at the
front of the charcoal canister.
Second Three-Way Connector: The second 3-way connec-
tor inboard of the air box splits the path of the hose once
again. The center barb, pointed at the right side of the vehicle,
is connected to a hose that runs through a hole in the air box,
where it mates with a third and final 3-way connector. The
hose on the end barb of the third 3-way connector is clamped
to the gold allen head screw on the venturi ring (so that the
center barb is positioned at the carburetor throat).

Figure 4-25. Charcoal Canister
Crankcase Breather Drain Hose: The end barb of the sec-
ond 3-way connector routes the hose to the right side of the
vehicle between the top of the air box and the bottom of the
frame backbone, where it runs rearward following the bottom
right side of the frame backbone. The hose then cuts back to
the left side of the vehicle through the opening formed by the
frame and the rear of the air box (just above the electric
starter). After returning to the left side, the hose passes
through the loop formed by the hose connected to the oil
drain/return fitting. The hose enters an opening at the front of
the passenger foot peg support where it is then clamped
along the inboard side above the oil drain hose.
