DFI System Wiring DiagramPiston Wear Inspection
Measure the outside diameter [A] of each piston 5 mm
(0.20 in.) [B] up from the bottom of the piston at a right
angle to the direction of the piston pin.
If the measurement is under service limit, replace the piston.
Piston Diameter
Standard: 75.959 75.974 mm
(2.9905 2.9911 in.)

Main Throttle Sensor Resistance Inspection
Turn the ignition switch to OFF.
Measure the main throttle sensor resistance in the same
way as input voltage inspection, note the following.
Disconnect the throttle sensor setting adapter [A] from the
connector of the main harness side.
Special Tool - Throttle Sensor Setting Adapter: 57 ...
Piston Ring End Gap Inspection
Place the piston ring [A] inside the cylinder (upper
crankcase), using the piston to locate the ring squarely
in place. Set it close to the bottom of the cylinder, where
cylinder wear is low.
Measure the gap [B] between the ends of the ring with a
thickness gauge.
