There are 6 positions numbered 1 to 6. On TRA drive pulley, note
that in position 1 the number is substituted by a dot (due to its loca-

TRA DRIVE PULLEY
1. Position 1 (not numbered)
Each position modifies maximum engine RPM by about 200 RPM.
Lower position numbers decrease engine RPM in steps of 200 RPM
and higher position numbers increase it in steps of 200 RPM.
Example:
Calibration screw is set at position 4 and is changed to position 6.
So maximum engine RPM is increased by 400 RPM.
4-TEC Models
From factory TRA drive pulley adjustment screws are set to position
3. This position allows the best compromise between acceleration,
top speed and fuel economy.
Position 1 or 2 would provide the best fuel economy. Top speed
would be reduced.
Position 4 would give the best acceleration. Fuel economy would be
reduced.
