Holy shit! Possibly carb problems?

Even though the jets could be the problem, do not discount the sync being the out, jetting would affect the mixture and would show up as a hesitation.

If you adjusted the idle by setting the butter flies and not the idle mixture screws, the same condition will occur. You should set the butterflies all the same (ie. they should open evenly) then adjust the idle mixtures to suit the cylinders. If the butterflies are uneven then the idle will behave similar to mis adjusted pilot jets.

Yup!  Jet it with a best guess and clean carbs that don't leak.  Set the synch, then start fine tuning things.  Otherwise you can chase problems by applying the wrong solution and just end up running yourself in circles.

UPDATE. Just received the 155 air jets from Randy and installed them , problem solved!
The needles remain where they were(circlip second from the bottom) and it is running beautifully.
Thank you gentlemen.
Now that I know the engine is good and is running properly I get to start the frame off tear down.
