It's a scooter that looks like a motorcycle! Got it for my wife. Takes premium.
Never warms up, so I've got a partial grill block over the radiator intake behind the front wheel. Hopefully a little less drag and a little higher operating temperature will help it out some in the power and economy categories. Also aired both tires up to 40psi, the value on the sidewall. Previous owner was running them at 20psi.
Possibly replace lights with LEDs as they burn out, but I can't think of anything else besides that. Feel free to tell me any more mods you can think of.
