I have been getting the itch to do something pointless and need to scratch it. I have heard about people converting their cars to run on propane. If it works on a car it must work on a bike right? I am just starting to research this so I know nothing, any input would help. A scooter gives me better room to hide the propane cylinder so I think I want to start with a cheap scooter. I was originally thinking a propane powered honda spree but I don't think a 2 stroke will work, obviously no lubrication, I don't think the oil injection will work with propane. If somebody knows better please let me know. So to the point of the thread: 1. Does anybody have any experience with propane conversions that can give me some pointers? 2. What bike/scooter would you suggest? 3. Should I put down the pipe and find something better to do with my time?
