75 cc Polini cylinder - sporty classic for V50 and PK50
The 75 cc Polini is similar to the D.R., a very good-natured and powerful cylinder. The workmanship is at a good level typical of Polini and promises a long service life. It is characterized by a somewhat sportier layout than is the case with the normal DR 75. Despite this sportiness, you don't have to compromise on durability.
Due to the higher compression ratio of 11.2:1, the Polini should be operated with premium petrol. As with the D.R., a 70-74 main jet and a W4CC are recommended with original add-on parts.
Dies ist bereits der zweite Zylindersatz den ich gekauft habe. Ich fahre ihn auf einer PK50 Lusso und bin absolut zufrieden. Nun habe ich den zweiten Satz bei einem Bekannten montiert, ebenfalls ein PK50.
