Brand new on the market - the Maxiscooter-kits from POLINI. Noticeable for their fine craftmanship, the POLINI kits sport water cooled gray cast iron cylinders with massive pistons. Both MALOSSI and POLINI get their cylinders from the reknowned Italian manufacturer Guilardoni, who also manufacturers serial kits for numerous other companies; all their products are first class quality. In line with that quality, the finely manufactured rings can handle higher rpm's. The kits enlarge cubic capacity of the motor being tuned, and depending on the motor, that increase can be substantial. You'll love the noticable power increase. A longer transmission would be an ideal complement to the POLINI kit, giving you a real punch - higher speeds without losing any power in the lower registers. Another consideration would be a tuning camshaft, feeding your cylinders better through longer valve timing. The kit for the old Piaggio ET4 P1400197 motor is an oversized piston. After honing up the orignal cylinder, the oversized piston can get maximum power out of your motor. The jets can remain the same, although you'll probably want to readjust them to optimize your tuning. The cylinder kit comes complete with piston, rings, diaphrams and gaskets. The test report from Scooter & Sport: says: "The POLINI cylinder delivers more power and top speeds". Test Roller special:"the POLINI variation runs soft and quiet with practically no vibrations..."
