Hey guys, I need your help. I have a Motograziella that is missing the flywheel nut. It's a fine thread, about 6mm in diameter. I tried a regular old metric fine threaded nut, but no go. I know some if not all of these threads are a special cut, but is it the same from manufacturer to manufacturer. The flywheel itself is a Bosch.
Any suggestions as to what might fit, something from another moped. I'm assuming Motograziella parts are non-existent.
