Description

Polini Tuning Kit, including piston, camshaft and CDI, for Vespa GTS / GTV 300cc. The kit includes a forged piston with pin, rings and circlips, a camshaft, a set of valve springs (x4), a complete CDI unit with cable and gaskets. The high-end tuning kit will increase performance considerably.The main factors coming into play are a redesigned performance-enhancing camshaft profile, with valve timings increased from 6.9 to 8.1mm, optimized valve closure and a forged piston that will raise compression to 12.1:1. The CDI Unit will allow for the required adjustments in fuel injection.

  • forged HQ piston for increasing compression from 10.8: 1 to 12.1: 1
  • HQ valve springs for improved valve closure
  • camshaft for increasing intake valve timings from 7.3 to 8.4mm / exhaust valve timings from 6.9 to 8.1mm
  • CDI / ECU unit + adapter cable, plug & play connection

The tuning kit will provide a very noticeable increase in power and improved torque, especially at high rpm.

Notes and Safety

When to replace the piston?

To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).

Extending Piston life

To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.

It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
