Thanks for all the imput and help. It seemed that one of the studs for the head/jug was starting to strip, and the exhaust valve was leaking pressure. So I swapped heads and we'll see how she fires up in the morning.

At least you "found something".
I just installed my BBK a few days ago and IIRC, I torqued the head bolts to 156 INCH pounds and the two side bolts to 97 INCH pounds. I think that's what they need to be at.
Hope that does it for you.

**Resolved** After changing the head and getting the motor back in, I hit the switch and she fired up immediately. Alter tearing the old head down and examining the valves, the exhaust valve was not only leaking, but was burnt. Pits and carbon build up was so bad that its hard to tell which has more. This motor has never run hot or had any overheating issues. I don't know why or how that much carbon could've built up in such a short time. I run the same gas in both my scoots and my other one has had nothing like this happen.. I'd post a pic, but I'm not sure on how to do it on here. Once again, I thank all of you for your help and input on my dilemma. -Slant-

One thing...in the OP you stated you had "good compression". With the ultimate discovery of a " exhaust valve was not only leaking, but was burnt", I'm wondering how you still had good compression.
For the benefit of others, what was the compression when you checked it? Compression tests are designed to reveal just such situations. If there is ANYTHING in a cylinder causing a leak, a compression test should give a clue.
Did you take any pictures of the valves and the pitting?
