Description
3V camshaft Vespa 125 from Polini
Polini tuning camshaft for 125cc and 150cc Piaggio and Vespa scooters with 3-valve cylinder head. Excellent addition for optimizing the 171cc Polini cylinder P140.0216.
With their specific profile, the opening times of the valves are optimized, resulting in a performance gain at all engine speeds.
By the way: In a 4-stroke engine, the camshaft is one of the parts that has the greatest impact on performance and engine behavior.
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.
