NOTE
The exhaust camshaft has a 1001 EX mark [A] and the intake camshaft has a 3154 IN mark [B]. Be careful not to mix up these shafts.
#4 Cam Positions [A] Intake Camshaft Sprocket [B] Exhaust Camshaft Sprocket [C]
The intake camshaft sprocket and exhaust camshaft sprocket are identical
Torque - Camshaft Sprocket Bolts: 15 N·m (1.5 kgf·m, 11 ft·lb)
If a new camshaft is to be used, apply a thin coat of molybdenum disulfide grease to the cam surfaces.
NOTICE
The crankshaft may be turned while the camshafts are removed. Always pull the chain taut while turning the crankshaft. This avoids kinking the chain on the lower (crankshaft) sprocket. A kinked chain could damage both the chain and the sprocket.
The timing marks must be aligned with the cylinder head upper surface [B].

Torque - Camshaft Cap Bolts (1 ∼ 18): 12 N·m (1.2 kgf·m, 106 in·lb) Upper Camshaft Chain Guide Bolts (19, 20): 12 N·m (1.2 kgf·m, 106 in·lb)
Armature Inspection
Using the × 1 Ω hand tester range, measure the resistance
between any two commutator segments [A].
Special Tool - Hand Tester: 57001-1394
If there is a high resistance or no reading (∞) between any
two segments, a winding is open and the starter motor
must be replaced.

Balance Adjustment
If the wheel always stops in one position, provisionally
attach a balance weight [A] on the rim at the marking using
adhesive tape.
Rotate the wheel 1/4 turn [B], and see whether or not the
wheel stops in this position. If it does, the correct balance
weight is being used.
If the whe ...
Premuffler Chamber Installation
Replace the premuffler chamber gasket [A] with a new
one.
Install the premuffler chamber gasket to the premuffler
chamber [B] until it is bottomed so that the chamfer side
faces exhaust pipe [C].
Install the exhaust pipe clamp [D] as shown in the figure.
Insert the projection [E] into ...
