Finally found a little while to dedicate to the ol' Intruder. I cleaned out the carbs and replaced the o-rings. I don't know how it affects performance, but one of the carb slides was lifting just a fraction before the other, so I got those balanced as well. I cleaned up and re-did a few connections and shortened both plug wires to get the caps screwed into some fresh wire. Also found a couple hot connections on the 5-pin located on the back side of the motor. One of those was for the lights, so they're working now. I don't know which of the things I did was the issue, but it's running like a top now, top and bottom end. Thanks again 8for all the advice and tips.
