Hello all,
Just purchased a new to me 2013 DS. I see Zero has a chain drive conversion available for the FX model. From my research the FX has a 75-5 motor while my DS has a 75-7 motor. I don't know what this means other than the -5 motor is smaller than the -7 motor in output and physical size. Would anyone know if the front pulley off a -5 motor will fit on a -7 motor or is the shaft a different size between the two? I would like to do a chain conversion for personal reasons. I'm less driven by efficiency and range, and care more about ability to change gearing when going to ride a couple sessions on the track. I'm sure I can get a rear pully made to fit but the front sprocket would be easy to source from Zero.
Thanks all. Lots of knowledge on this site.
