Re: Still getting really bad gas mileage.
It 4 strokes just a bit around 1/3 throttle when it is not yet heated up fully, and always at full throttle, no matter what temp it is at. It runs great when under heavy load, such as fast acceleration, steep hills and burnouts. And i am still using the kit plug, but i will be getting a few NGK ones today. I do shut off the fuel valve when i park, and it is stored over pavement, so even if it was dripping i would see it.
My motorized bicycle is cooler than your Vespa, even though you can go faster.
