I need to take some dimensions under the sheet metal although I'm thinking a liquid cooled single or twin might be my best bet after all for this project. I feel I can hook up a shifting linkage to mate up with original floor board shifting hardware. Any ideas on what engine would be the most compact in size? I'm not really sure what has been produced in L/C form in 250-400CC 4 stroke over the last 20 years or so. I have a couple ideas on locating radiator without cutting any sheet metal. 12 volt lights,etc will be a nice upgrade too.
