Gruppo Termico Polini W 50 Peugeot 103 Ac

Polini 50cc Cylinder Kit "Alu W", d=40mm, Peugeot 103 AC, with hard-chrome plated aluminium cylinder and a single-ring piston. The kit has impressive power at high rpm range (appr. 6hp at 9300rpm, according to Polini) and very convincing torque for a 50cc cylinder. Its unique feature: the W-shaped exhaust port. We recommend combining the Polini 50cc Cylinder Kit "Alu W", d=40mm, Peugeot 103 AC with a 15mm carburetor (at least) and a high-rpm sports exhaust. Although you can use your original cylinder head, we recommend replacing it with a high-compression cylinder head for even higher performance. The kit does not include a cylinder head.   Street-legal! Note: If you want to mount this kit on a Peugeot Fox, you'll have to use a sports exhaust! In case you want to use the original exhaust, the exhaust flange has to be modified.
