Review on ⚡ Revive Your Spark: Perma-Coil 1210-410 Spark Plug Thread Repair Kit - 6PC by Jose Strong

Used it to repair some broken spark plug threads on my 2007 Ninja 250. Big. I used the ninja250 FAQ as a repair guide and it turned out to be a lot more complicated than it actually was. It was tedious and time consuming, but not difficult. My previous engine experience has only been valve timing on a Ninja.
