Description

This每Polini每tuning kit每was developed especially for the 300cc Vespa GTS/GTS Super/GTV models and includes a camshaft, valve springs, piston and an ECU injection unit in the delivery.The redeveloped每camshaft每profile provides a noticeable increase in performance. The inlet valve timing has been increased from 6.9 to 8.1 mm. This delivers an extra portion of torque and raises the maximum power output. The每valve springs每included prevent any valve flatter and the forged每piston每raises the compression from 10.8:1 to 12.1:1.The conversion每ECU fuel injection module每allows the fuel supply to the fuel injection unit to be adjusted as required and the adapter cable enables ?plug and play? connection to the existing fuel injection unit. For this kit to optimise its potential, it can be paired with a sports performance variator – the Polini 9-roller variator will provide the optimal combination. Also consider the Polini performance exhaust.
