I recently learned through this forum that it seems you can repair these with super glue (no kidding) if they are just leaking. Clean with brake-cleaner, apply super glue (this very liquid glue that dries up in seconds) around the leaking area (the outside!! of the neutral switch, not the part that goes into the engine!) and let it rest until fully dried. Put it back on the bike and see if it's fixed. cheap and easy fix!
