How to Adjust the Idle on a Four-Stroke Motorcycle Engine

Model: (Various brands) Various
Part: Engine

Video tutorial

The adjustment process is based on a screw located on the carburettor or throttle body. The primary aim is to find the exact RPM of the engine at idle to improve fuel consumption and achieve perfect balance.

This principle applies to any motorcycle model, as the adjustment screw does not differ. To proceed, after allowing the engine to warm up, use a small screwdriver or your hands if possible, to turn the screw clockwise to increase RPM or counterclockwise to decrease it, thus achieving the optimal result.
