COMPONENT INSPECTION AND ADJUSTMENT
1. If engine is not completely cold, remove throttle body from engine. Then, wait for at least 3 hours.
(This step - is necessary to bring the temperature of the thermo-element to the room temperature.




2. Measure thermo-element stroke (L) and room temperature.
3. Check thermo-element stroke (L) as shown in the figure. If the stroke is not within the range 1 replace thermo-element with new one. Then return to step 1 again.







4. Adjust clearance (A) between throttle stopper and throttle adjusting screw to specification by turning adjusting screw (S).




5. Rotate adjusting screw (S) clockwise or counterclockwise by Z turns according to the following equation, then tighten the adjusting screw lock nut.

Z = (L-LS*)
Y

*: Value of the specified line (LS) at the temperature of thermoelement actually measured.

Y = 0.8 mm (0.031 in)

^ Direction of adjusting screw (S) rotation
1. Positive (+) Z: Counterclockwise
2. Negative (-) Z: Clockwise
