A TTR 125 is considered slow for its size. However, many people say that it suits them just fine and it just depends on how you plan to use it.
Try www.bikebandit.com, they have a large selection of oem and aftermarket spark plugs, if you keep fouling plugs try to rejet the carb, or swith to a hotter spark plug.
If you mean that the wire came out of the boot, then pull the boot off of the spark plug and use a spark plug socket to remove the spark plug.
Remove the spark plug wires from the spark plugs, use an extension for your Allen wrench, and use a spark plug socket to remove the spark plug.
The best way is to use the spark plug socket out of the factory tool kit. If you do not have that use a normal 5/8" socket to loosen the spark plug. Use the spark plug wire to snap back on after the plug is loose and pull it out. The spark plug is at the very top of the engine, the spark plug wire is a real good indicator of its location.
use the spark plug wrench and use used mirror to find the rear spark plug, you need to two person to do this, then fell the spark plug rear with your hands then apply the spark wrench to remove the old spark plug.
