In this video, I perform a full valve clearance check and shim replacement on a Honda CB500X. Watch as I remove the necessary components, measure valve clearances, and discover that all 8 of my shims are in need of replacement. I replace the shims, install new spark plugs, and replace the valve cover gasket. Afterward, I reassemble everything to ensure the engine is running smoothly. This step-by-step guide is perfect for those looking to maintain their CB500X engine for optimal performance and longevity or just like me, you're preparing for a long trip.
