covers and 2 gaskets.
23. IF NECESSARY, REMOVE SEMI±CIRCULAR PLUGS
AND CAMSHAFT HOUSING PLUGS
24. REMOVE CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.

2. DISCONNECT FUEL SUCTION TUBE
Remove the 2 tube clips, and pull out the 2 fuel tubes.
NOTICE:

Before this operation, check the connector for dirt,
mud or other contamination. Clean if necessary.

Be careful of mud. The connector's O±ring, which
seals the pipe and connector, is easily contaminated.

Do not use any tool in this operation.

Do not bend or twist the nylon tube. Protect the con-
nector by covering it with a plastic bag.

When the pipe and connector are stuck, push and pull
the connector to release and pull the connector out
carefully.
