SWEET, i found a moped in the garbage, i will post some pics later. That thing is sweet. BTW when you did your speed calculation on the first page, you did 3600 RPM, that motor is a 2 stroke, it most likly is more in the range of 7-8,000.
Its a Honda PA50I so the slower of the 2 models of that year. It was sooo sweet how i got it, my buddy actually found it, then hes the kind of person that wants to buy a running thing than fix one thats non running and he asked if i wanted it. In my mind a JACKPOT sign lit up. ill post a thread and pics later. Im having trouble with the carb though.
