Step-by-Step Guide

Step 1: Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental electrical shorts.

The spark plug on the 1991 Suzuki DR650SE is located on the top of the engine. Remove any components obstructing access to the spark plug, such as the fuel tank or seat, if necessary.

Apply a small amount of anti-seize compound to the threads of the new spark plug. This will make future removal easier and prevent thread damage.
