1. Code all identical parts (such as piston, piston rings, connecting rods, and valve springs) so that they
can be reinstalled in the cylinder from which they were removed.
2. Clean the parts with a steam cleaner. Blow off any remaining water with compressed air.
Note
l During disassembly of any part or system, be sure to study its order of assembly. Also, note
any deformation, wear, or damage.

INSTALLATION
Step 4
I. Connect the hoses shown in the figure.
Caution Speedometer cable
1. Install the speedometer cable.
Exhaust pipe
1. Install the exhaust pipe and a gasket; then loosely tighten
the lock nuts.
2. Loosely tighten the bracket bolts.
3. Tighten the lock nuts.
Tightening torque:
31-46 N-m (3.2-4.7 m-kg, 23-34 ft-lb)
4. Tighten the bracket bolts.
Tightening torque:
37-52 N.m (3.8-5.3 m-kg, 27-38 ft-lb)
l Position the hose clamp in the original location on the hose, and squeeze the clamp lightly
with large pliers to ensure a good fit.

26 POOR FUEL ECONOMY
DESCRIP-
l Fuel economy unsatisfactory TION
[TROUBLESHOOTING HINTS]
While fuel consumption is drastically increased by city driving, short-run operation, stop and go driving, extended winter
warm-up periods, etc., as opposed to “trip” mileage, an attempt should be made to determine these factors when con-
fronted with “poor mileage” conditions. However, since the operator is not always at fault, the following is offered.
@II Operator depressing accelerator more than usual due to
@ Air/Fuel mixture too rich
low engine power
l Poor ignition *High fuel line pressure
@ Alcohol blended fuel used
*Low intake air amount
l Electronic spark advance control system malfunction @ High vehicle load l Low tire pressure
*Clutch slipping/ATX slipping l Incorrect tire size l Exhaust component restricted l Brake dragging ;TEP

F ENGINE TUNE-UP
23UOFX-046 Note
l When the parking brake is not applied, the idle
speed for ATX model (Canada) is approx. 800 rpm. Idle Speed
1. Perform “Preparation”. (Refer to page F-79.)
2. Apply parking brake.
3. Check that the idle speed is within specification.
Idle speed (Neutral or P range): 700-800 rpm
Caution
l Check the idle speed without the electric cooling
fan operating.
4. If not within the specification, adjust the idle by turning the
air adjusting screw.
5. Disconnect the SST.
