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

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

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 Both problems can be fixed, however it would be a lot nicer if these issues were fixed in a newer version of the kit.

Good Maintenance

Here are some tips to keep the Pinasco running smoothly:

• Keep the exhaust clamp tight! The Pinasco is an aluminium barrel and the exhaust is metal. If the exhaust vibrates against the aluminium it will wear the aluminium down. The result will be cracked exhausts due to everything being supported by just the one exhaust bolt under the scooter. Also, as the aluminium will be worn, the exhaust clamp will never tighten properly. One tip is to use springs to back up the exhaust clamp, you can either weld a lug to the exhaust (which is neater) or use an exhaust clamp. Secure the exhaust to the engine with a strong spring from the cowl screw or drill a hole in a fin (or both).
