This was on discovery channel yesterday... Not much was correct what they said or did. They told at first it was an 18HP engine (no 12 or 13,5). They did say that they installed a centrifugal clutch. Didn't see them doing it and it wouldn't fit on an non centrifugal gearbox. They fiddled around with a carb and the jets, but they didn't show how or what so i doubt that too. They found an original rear seat frame (narrower) and then they installed normal seat cusions that overlapped quite a bit in the middle. Much blabla...
