Pinasco 215

Comparsion to Standard

• Bore = Standard 66.5mm Vs Pinasco 69mm
• Bore length (from top of cylinder to bottom gasket face) = Standard 98.48mm Vs Pinasco 98.00mm
• Exhaust Port Closing (from top of cylinder yo top of exhaust port) = Standard 39.32mm Vs Pinasco 37.93mm
• Cylinder head spark plug depth (gasket face to top of electrode) = Standard 17.7mm Vs Pinasco 15.7mm (wrong!? Another comparison shows these are the same!? Are there differences between standard heads - anyway don't trust this info, more investigation is required)

Good Points

The Pinasco kit is a very easy install (see Pinasco 215 Installation) and gives instant and reliable power. Ports can be matched for more power, however the kit can be fitted to a standard scooter and removed at a later date (i.e. changes can be easily rolled back to a scooter under warranty). The power is not reliant on high revs and makes for a good performing engine around town and out on the highway.

Bad Points

The kit has been altered over the years and isn't to the original design. Most notibly the piston is not the original and is adapted from another kit, which means that the Squish Band is all wrong at around 3mm (where ~1mm would desired). The excessive clearance has lead people to believe the kit was designed for a long stroke, however if a long stroke is fitted the compression is too high and spark plug clearance too low. More performance can be gained by reshaping the head (which is what Worb5 do).

The kit is also probably designed for a Vespa PE (not PX), this would explain why the port does not match up exactly and there is not enough clearance for the starter cog. Both problems can be fixed, however it would be a lot nicer if these issues were fixed in a newer version of the kit.
