Just when I thought Malossi Sport 2013 is my choice then this appeared: blog.scooter-center.com/vespa-zylinder-pinasco-225-super-sport/You can change the language from right. Luckily I don't have to decide at this moment. 225cc long stroke would be nice (but a bit pricey for me). No modifications needed for crank case.  |

No mods required to inlet because they're poo. Only one transfer in barrel as per standard barrel. Stick with the Malossi kid and stroke that instead.

How about those holes of the piston? I'm only guessing, but maybe holes do the same than additional transfers of Malossi?

I'd imagine the piston windows to act as additional transfer area but nowhere nearly as efficiently as a Malossi 210 piston as it also utilises the side transfers in the casing......... besides this is what happens when your windows are as massive as they are on the Pinasco.  |

Not nice. How old the piston is, or how much it was used?
I've been told that some 2 stroke engines needs new piston every 10 000 km or so to prevent piston breakage. I'm not sure if I want to do that, but it may be needed if you take a lot of power out of Vespa's engine.
