Hi there, I have just bought a suzuki fz50 as spares and repairs. I am completely new to mopeds and anything mechanical in any way so I'm trying to teach myself and learn as I build this moped up to something that will run again. My question concerns air filters. What performance air filters fit the fz50 and how easy is it to fit these? do they simply bolt on or will I have to alter something else to fit? I would appreciate any help with this please folks, ben
