Description
rocker arm Pin - original spare part Piaggio 4T 4V
The well-known scooter and moped manufacturer Piaggio offers spare parts for all Piaggio and Vespa scooter models.
By using genuine spare parts, you can restore your scooter to its original condition. The parts are identical to the standard equipment and can therefore be installed without any modification.
The camshaft and valves are part of a 4-stroke engine. The camshaft controls the opening and closing of the valves via a timing chain. Worn components should be replaced as soon as possible.
Piaggio OEM part number: 842174
Camshaft and valve timing
The camshaft and valve timing are important components of 4-stroke engines. The camshafts allow the valves to open (i.e., to draw in the mixture and expel the gases) and are driven by the timing chain, which is in turn connected to the crankshaft.
Incorrect timing adjustment interferes with valve opening and can severely affect engine performance and reliability. Therefore, we recommend to intervene only with appropriate technical know-how.
Maintenance and tuning
Maintenance and care of the elements located in the cylinder head, including valve timing, is very important. Even though the timing chain generally has a fairly long life, it is still necessary to regularly check chain wear and wear of all related elements.
Camshafts must always be in perfect condition. You can also use tuning camshafts; the shape of the cams is revised to increase the valve opening times and thus provide more power.
