For many motorcycle engines of the brands Aprilia, BMW, Kawasaki, Yamaha. Shims, commonly known as adjustment plates, are precision-engineered, thin metal discs used in motorcycle engines to precisely adjust valve clearance. These small components play a crucial role in the maintenance and optimization of the valve system to ensure smooth engine performance. Shims are individually selected and inserted into the valve mechanism to ensure the correct distance between the valve lobes and the valves. By using shims, valve clearance can be precisely set to manufacturer specifications or individual requirements, ensuring optimal engine performance, efficiency, and durability. These highly precise adjustment plates are indispensable tools for motorcycle enthusiasts and professional mechanics to maximize engine performance and reliability.
The specific heat treatment ensures the hardness of the shims, allowing for maximum hardness and reduced wear.
The adjustment plates/Shims are manufactured through a special heat treatment process for maximum durability and minimal wear. Each adjustment plate is precision-machined, ensuring a perfect fit and is labeled with the exact size. Please ALWAYS measure or compare BEFORE ordering! To determine the correct valve adjustment plate, you will need the following data: - the measured clearance - the desired clearance - the current height of the valve plate
You calculate as follows: Measured valve clearance minus desired valve clearance plus current shim height This will then give you the new required height of the adjustment plate.
