Description
This Malossi Camshaft Power Cam Vespa LX 4V / S 4V 50cc is a high-end tuning part, recommended for racing and tuning.
It is the result of many years of experience and superior technical know-how, developed to add a sporty edge to your scooter. CAD/CAM development, the use of extremely precise equipment for manufacturing and quality control with measuring instruments providing accuracy to one tenth of a micron - this is by all means a technological gem. It is made of a high-strength steel alloy and very durable.
Extended valve opening times improve torque, especially at higher rpm, and acceleration. Your scooter will be more zippy in the city and have a higher average speed. Climbing hills is a breeze with this camshaft.
Note: can only be used with a Malossi 79cc cylinder (article number M3113905).
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.
