We all know how important valve maintenance is for our Honda CRF motocross bikes. Excessive valve clearance will cause noise and eventual engine damage. Little or no clearance will prevent the valve form closing, cause valve damage, and a loss in power.
The valve clearances should be inspected after every 30 hours or riding. Paying a mechanic to do this for you can get expensive fast. This application makes the process more manageable by providing instructions as well as tools to help you along the job.
