Finally after going to 4 honda CB shops and mechanics I was able to figure out the problem.
Honestly stupid mistake all ways happens to new backyard shade tree hobbyist.
So I went to Lucky Wheel Downtown Los Angeles everybody was working honda and everything was so cool there.
I was told again and again sounds like an airleak from the carb to heads. I said my rubber manifold tubes were good and I sprayed carb clean to check for leaks.
So he mentioned after the bike heats up 1/2 hour later the rubber becomes more flexible and still can leak air.
So I went home and tighten the clamps until the screw didn't move anymore. My opinion I thought they were tight enough...because I didn't want to strip the nuts...
Apprently, you need to tighten and check the rubber manifolds. Mine got air leaks when the bike get hot.... Lesson Lean!!!
" Tighten screw camps until no more movement" I hope this helps other CB riders....
