If I Have Current Through The Spark Plug Wire, But The Plug Still Won’t Spark, What Could The Problem Be

It’s a ’71 yamaha dt 250. It’s a new spark plug and I replaced the stator and ignition coil with used parts. I even tried a couple different spark plug caps and got the same results.
river rat, ground it? run a wire from the plug wire to the frame?
