Tuning kit -MALOSSI 70 ccm- CPI AC (Euro 2) - basic set

Malossi 70 cc tuning kit basic set for CPI 50 AC Euro 2

Our SCK cylinder basic sets offer an uncomplicated and quick start to give your bike a boost. Do you already have the skills, but lack the experience to know which components harmonize well with each other? This is where our ready-made kits come in, providing the basis for a powerful, durable engine suitable for everyday use. In order to achieve good acceleration and good pulling power, you need more torque, which also increases performance.

Why a cylinder kit is the better tuning start

All attempts to get more acceleration out of an engine with little power, for example with a different clutch or variator, are usually unsuccessful, as they only try to transfer the available power perfectly to the road. If there is little power available, even the best sports variator can do little to improve acceleration. That is why our base kits start directly where the power is generated, in the heart of the engine. Here, not only is the torque greatly improved with the help of a larger displacement, but the inner cylinder design of the scavenging channels and their larger dimensions also considerably improve performance across the entire rev range.

Malossi 70 ccm - sporty, durable and suitable for everyday use

The cylinder we have selected, the Malossi 70, which has proven itself over the years, is a fully suitable companion for everyday use, but still a sporty one. The Malossi combines an agile and lively throttle response with a wide rev range under load. This enables it to master the difficult balancing act between good acceleration and high top speed and also responds very well to further tuning measures such as a sports exhaust and a larger carburettor

. The kit contains the basic parts to enable the engine to develop its full power. An open intake manifold and larger carburetor allow the intake tract to breathe freely, and the cylinder responds with a greatly improved performance and better durability thanks to increased internal cooling. The sets can be easily combined with the standard exhaust, are then absolutely inconspicuous and already considerably more powerful than with a standard cylinder.

An inconspicuous sports exhaust in a series design, such as those offered by Tecnigas or LeoVince, rounds off the overall package perfectly. Even better performance combined with a quiet, approved exhaust makes a 50cc scooter a very fast vehicle that does not draw attention to itself through noise and revs in everyday use.

Carburettor tuning with enclosed jet set

In order to be able to adapt the carburettor individually to the various existing conditions, such as a sports exhaust, each kit includes a jet set for the respective carburettor

. If a main jet that is too small is used, the engine can wear out within a very short time and destroy the cylinder. The basic rule for a durable and well-tuned engine is very easy to realize. It always starts with choosing a main jet that is so large that it causes the engine to stutter under load. Starting from this, you slowly work your way down, i.e. starting with a jet size 88, for example, you select a smaller and smaller jet size (86, 84, 82 etc.) (in the respective jet gradation) until the scooter no longer stutters under full load. This gives you a very good starting point for further fine-tuning via the carburettor needle, secondary jet, etc.

A Malossi Sport 70cc with a 17.5 mm carburettor and a corresponding exhaust already mobilizes around 10-11 hp at the rear wheel, which means it could easily pull a longer gearbox if a further increase in top speed is desired.



All in all, the foundation for a solid engine tuning that remains suitable for everyday use and low in fuel consumption despite the increased power.
