It sounds like you have a vacuum leak.
Just to throw more fuel on the fire.. have you checked the valves?

I'd add a valve check to your short list of things to do to that machine. If you find tight valves on one cylinder it might explain some of this. Maybe.
Anecdotally : I acquired an SV650 (also a twin) recently that had the valves timed 180-degrees out of phase. Both cylinders were set to open intakes, exhausts, and make power, etc on the same stroke. Made for a very strange running behavior. Idled like shit, came into power mid-band and then tapped out early (even for an SV).
Not saying this is your issue as you have a cold header. Just saying it may be worth your time to check the valves and timing. I swore I had one jug not firing too and it turned out to be valve timing instead.
Look at mister Moto GP Big Bang SV in here! :P
Usually only the ladies call me that..
Ok so compression test complete both cylinders are running on the low side but still within spec. And the cylinder in question has slightly higher compression than the good cylinder.
Well I took it out for a spin the the highway. And she ran pretty good. A slight hesitation around 9k. Other than that and me running out of gas...... (Ya I know) she seamed to do good. Now I've never ridden a good running he acts before so I have nothing to compare it to. I'm going to load it up on the truck and take it to the track of me Sunday when I come to watch and meet you guys. Then you guys want to help me and give it a once-over that be greatly appreciated.
I'll be up Saturday. That would be great I've already talked to him on Facebook about a belly pan.
Don't let smutty near it. He'll rub his nuts on it.
