I also notice that, but i worry that when i bring the throttle down while maintaining the same RPM i am causing it to run lean. Also, where is the clip on your carb needle set? Mine seems to be running a little lean with the clip at the second notch from the top.
My motorized bicycle is cooler than your Vespa, even though you can go faster.
