Firko did you have to modify the frame to fit the Paul Maico 250 engine in or do the Zundapp/Metiise frames fit all types of engines ?cheer
Alison, the only mods needed to fit the Maico engine have been fabricating front and rear engine mounts, designing a new head mount and a slight modification to the clutch cover to fit inside a frame rail. Whether all types of engines fit is a big doubt. I do know that Yamaha DT1/RT1, Maico250-400, Honda SL125, Triumph Tiger Cub 200cc and BSA B25 engines fit for certain, everything else would be on a suck it and see basis. I have also discovered by accident that a Maico swingarm is almost a bolt in, giving the bike a much needed extra 3" of wheelbase. Everything to do with these engine swap bikes is all trial and error and hammer and chisel boilermaker technology.
