| Description | Unique Malossi 210 "power valve" cylinder kit. I modified this cylinder when I was a very active engine builder/scooter racer... now I'm just old and need to get rid of stuff.
It was one of the very first power valve mods ever on a Vespa (was featured in Scootering mag, etc).
Cylinder is in perfect shape and comes with a fresh piston and modified Cosa head.
It's an awesome thing to ride... you have to run some cables to actuate it and then you can easily switch mid-ride from super low end Polini-like torque to fully opened up Malossi high rev peak power and back. More pics of the internals via email. I might have some old dyno curves somwhere, too. I think it's worth $800. Let's talk.
