Okay folks, hear me out on this one: I just moved to the Iowa City area. Downtown Iowa City basically being a college campus, there are TONS of scooters everywhere. They are even allowed to park on the sidewalk in front of bike racks (which still blows my mind in a city with parking enforcement as anal as this). While I don't have any trouble finding a free place to park my KLR, every time I see a swathe of scooters roll down the road I get ideas about building a 'battle scooter'. Something mean. Nasty. Maybe even loud. But, I don't know if it is cost effective to do this. And since I weigh about 240 right now (and even if I lose a bunch of weight this summer I will probably still be in the 220 range), it would need some serious juice in order to get me up to speed. Can you get performance expansion chambers for Stellas? What's about the upper speed/power limit of the smaller scoots? I need something that's a sleeper in order not to arouse the ire of the other scooter kids or the authorities Most importantly, could a project like this be completed over a summer for less than $1500?
