You can't. The computer controls the air/fuel mixture depending the information it receives from various sensors. If one of the information it receives is incorrect, this can affect the air/fuel mixture.
There are adjustments that can be made to the autolube pump, but a dial indicator is required (plunger adjustment). You can also adjust the cable free play to ensure it opens as soon as you twist the throttle. That part only requires a 10mm wrench & an adjustable (or 2 10mm's).
These units are extremely reliable & hardly ever require adjustment. If the bike seems to be running rich ( on oil ), there is most likely other issues -- clogged air filter, plugged exhaust (common if pump was bypassed & premix used), spark plug of incorrect heat
range or plugged jets/air passages.
