Ok fellas before I tear something up...just how does the llight swith knob come off on the 71 Demon? I looked for an allen screw, I pulled and I twisted , but to no avail. I have screwed with it sooo much, I am going to order a new switch just in case. I saw that the new switch does NOT have the stem sticking out of it that has the knob on it...can anione tell me what to do ?
