Camshaft POLINI

TUNING SPORT – high-performance
For race use only. Not admitted in the area of the German StVZO!
Product description
The Italian scooter tuning specialists POLINI have developed and produced a more extremely profiled performance camshaft especially for the 300cc scooter motors made by PIAGGIO. The inlet timing has been raised from the standard 7.3mm to 8.4mm and the timing of the outlet from 6.9mm to 8.1mm. These increases guarantee a boost in both torque and overall performance from the motor. This camshaft kit is only suitable for use in combination with the P1400317 cylinder kit, if you wish to retain the standard piston it will require expert modification! -TIP : A camshaft installation/replacement requires mechanical knowledge and skill to complete properly. If you are not entirely sure of the procedure be sure to get some advice/help from somebody in the know at your local scooter club/repair shop to avoid any expensive mistakes. If you are tuning a PIAGGIO Leader motor we have a workshop manual available (#578905) which clearly explains this particular job and of course many other mechanical adventures! As a result of the extra performance valve flutter is inevitable unless stiffer valve springs are also fitted while mounting this kit.
