I am trying to have my motorized bike registered with the State of Ohio. I sent in the registration form and (believe it or not) they responded. They want some sort of proof that the motor is less than 50cc and 1 horsepower. Of course I have a 66cc mounted to this bike currently. Now I am looking for the elusive 48-49cc/1hp motor. does anyone have a line on this motor? I could also de-tune a 50cc/2 hp motor. does anyone know how to do this? I guess they would like proof of this de-tune. We are using the bikes to travel the island areas of Lake Erie. We are not trying to go fast at all. 10-15 mph would be fine especially since another Ohio requirement is "no speed in excess of 20mph".
