Tuning kit PINASCO Endurance Slave 252 - cylinder incl. crankshaft - reed valve inlet on cylinder - Vespa PX200

The PINASCO Endurance Slave 252cc kit is aimed at riders who want to build up a very powerful touring setup without having to mill the standard engine housing. The main difference to the classic rotary valve setup is that the engine is supplied via a reed valve inlet on the cylinder. This provides very good filling and a wide usable band without the rotary valve surface or the housing inlet being a limiting factor.

Aluminum cylinder 72x62 = 252 ccm Diaphragm on cylinder Crankshaft included No spindles necessary

Why the slave version?

Diaphragm inlet on the cylinder: stable filling over the entire speed range
Standard case-friendly: no machining required on intake or rotary valve
Touring DNA: high torque, smooth running, low vibrations
Plug-and-play installation: no spindles on the engine housing due to the cylinder neck being omitted

Diaphragm intake on the cylinder: what this means in practice

In this version, the mixture is supplied via the inlet on the cylinder. This is particularly useful if you want to realize a very powerful setup on a standard housing without milling the housing inlet or using a possibly worn rotary valve surface as a base.

Advantage: The cylinder inlet delivers very consistently, the setup can be planned and is "series housing-friendly"
Note: Suitable components are required on the intake tract for the conversion (diaphragm, intake, carburetor tuning)

Ignition timing

Ignition timing: 19° at 2500 rpm (original)
Ignition timing: 24° at 2500 rpm (Flytech)

Recommendation: Always check squish, compression and ignition timing on the finished engine and adjust to the overall setup.

Suitable for

Vespa PE 200
Vespa PX 200
Vespa Cosa 200
Vespa Rally 200 (Ducati)
Vespa Rally 200 (FEMSA)

Conclusion

The PINASCO Endurance Slave 252 kit is the right choice if you want to implement the 252 set-up on a standard housing as simply as possible and deliberately opt for a reed valve intake on the cylinder. Very powerful, very suitable for touring and, thanks to the plug-and-play design, can be implemented without spindle work.
