It's really odd...that's really spiratic for a vacuum leak at constant throttle. I'd say it's more of an electrical input vs physical issue.
I finally got my bike back together; new rectifier(holds strong @13.99V), and I noticed while running it cold that under steady throttle moving out of the garage, in gear, it would give a nasty hiccup. So, I warmed it proper and drove down the street where it stalled in a u-turn. I noticed the symptoms go away as it warmed up. I rode to work without any issues/visible damage, and the absence of burnt wire smell was relieving. Apologies for the long story, but I noticed while switching out my throttle cable that my Map sensor(south of the lower air box cover) case looked a bit scathed. Maybe an internal issue with that sensor. I've had my bike run nasty when that sensor's vac line is disconnected so I'm guessing it has a major influence on air/fuel and load.
Also, I'm not master tech so please critic, correct and bring to light any falacies in my post. I'll keep updating as I discover new leads!
