I thought the technique in doing this was the Choke out?  meaning pulled out like I was going to start the bike?

I really hope you are all right and I am wrong.  I dont want to park this bike for the summer and be fixing engine,  (was going to do that in winter with paint etc.)

Trust me on this, if you pulled the choke, that is the issue with your compression readings.
Do it again, this time with the choke off... knob pushed in... fully open... however you want to say it. Let her inhale and squeeze that big breath of air. That will get you an accurate reading.

Think I will try the jet kit.  I have heard a few people say that after adding a 4 into 1 pipe a jet kit is necessary.  Just havent felt any carb issues, so was thiking something more complex.

If it ain't broke, don't fix it. Adding a 4 into 1 if it has a deicent street silencer (muffler) shouldn't require a jet change. Now if you are running an open header or a exhaust without baffles, that's a different story.

If the valves have a carbon build up, any way to remedy it without removing heads?

Havent checked valves yet, but engine sound doesnt indicate a valve issue

Yeah, there are a couple old school shade tree mechanic remodies,  But I bet once you do the compression test properly, your engine will be in better shape than you thought.
