I have about 1000 dollars into a nice small performance scooter. It started life as a Honda 1989 EliteE a single speed 25 mph scooter. Cost 400 in good running condition. After being totally bored with it, I bought a performance DIO engine Built into 86 cc with a big bore and stoker kit for 500 dollars and modified a Honda CR85 pipe to fit on it. I have had it to 55 mph so far. It handles better than I would expect. Can get air under the front tire at start. Here are two very short youtube links before I really got it going.

It weighs 120 pounds without the two back panels and tail light. Good luck at having something that pulls you nicely.
