I'll save you guys the trouble, I"M AN IDIOT! This is what my spark plug hole looks like right now. This is the other end of the guilty PART! This is how I screwed it up. Replacing the spark plugs should be easy right? After gettin started today I found a local KTM shop sold me a USED SPARK PLUG!!! Of course they are closed until tuesday! So off I went to two different auto parts places before I found a NEW plug. Then I realize none of my spark plug wrenches are thin enough to fit down the tight shaft. The guilty tool you see above is a spark plug wrench from my Aprilia tool kit. I found that if I filed down the corners of the cheap pressed steel wrench it just barely fit. I was unsrewing the plug when the resistance began increasing from the tight walls of the shaft. Then SNAP! The spot welds on the wrench broke. Now I have the spark plug wrench STUCK in my engine! I removed the valve cover and spark plug insert to get more access to the wrench, but I've only been able to pull on the wrench with needlenose pliers, and it ain't budging. I took a 5/8" bolt and ground it down enough to fit inside the cylinder, but the threads won't bite the steel enough to apply upward pressure. ANY IDEAS? I really need my bike back together pretty quickly.
