I've been following a thread on the XR250/400 forum about removing the resistor in the spark plug boot to make a hotter spark (or whatever). My 600 can be a difficult starter when it's cold out; this is supposed to make it easier to start. As this is a free mod and completely reverseable I'm going to do it anyway. I have this whole week off of work if I choose and need an easy project to fill some time. What is the forum's thoughts/experiences with this? "O"
