Every 2,000 km, you must run a "pump stroke volume test." Disconnect the oil line into a graduated cylinder, run the engine for 200 revolutions, and measure the oil. If it isn't 2.5cc +/- 0.2cc, you replace the pump. Most owners skip this. Most KB 50 top ends die at 8,000 km. 4. Ignition Timing: Points vs. CDI Early KB 50s used contact points. Later used a CDI. The service manual covers both, but the critical part is the stator plate alignment .
The manual provides a torque chart for every M6, M8, and M10 bolt. The clutch nut? 45 Nm. The flywheel rotor? 55 Nm. The tiny screws holding the oil pump cover? 4 Nm. "Gudentite" is not a unit of measurement. The KB 50 wiring loom is a spaghetti monster. AC headlights (meaning they dim at idle). A 6V system (later 12V). A kill switch that grounds the CDI. A horn that runs on AC.
You can find a PDF of the OEM Kymco KB 50 service manual in the depths of a scooter forum. Print it. Spiral bind it. Get grease on it.
