900 L4-1985cc 2.0L DOHC Turbo EFI (1985)
Throttle Body: Adjustments
Basic setting of throttle butterfly, LH 2.2
1 Make sure that the butterfly is mounted centrally in the throttle body.
2 Screw in the adjusting screw until it touches the stop (butterfly fully closed).
3 Turn the adjusting screw a further 1/3 turn and secure it in this position with a locknut. This will ensure a clearance between butterfly and throttle
body of approx. 0.05 mm (0.002 in).
4 Check that the length of the throttle cable does not prevent the butterfly from reaching the idling speed position, and that there is no play at the
accelerator pedal.
5 Check that the butterfly opens fully when the accelerator is floored.
Check and adjust the throttle position sensor.
