Pre-throttle valve clearance - adjustment

Fuel and exhaust systems - Digijet fuel injection / Pre-throttle valve clearance - adjustment

The pre-throttle valve clearance is set during production and under normal circumstances should not require checking and adjustment.

If the clearance is to be checked, first remove the air cleaner unit. Using a suitable 0.5 mm diameter twist drill, check the clearance at the point indicated (see illustration). If adjustment is required, loosen off the locknut and turn the adjuster screw in the required direction to set the clearance, then retighten the locknut.
