When the light turns green, do you wonder if your 2 Valve Vespa LX 50 will make it across the intersection before the light changes to red? This should speed things up a bit.
This is the Cylinder kit Piaggio uses in the 80cc Versions of the same 2 Valve engine. It is complete, bolts right in, and doesn't require any other adjustments or changes.

We got a special deal on a bunch of them, and decided to pass it along.
