Am I too RICH or too LEAN!!

[kingster1]

I have learned so much from working on this banshee.  I still have a low end bog and tremendous smoke.  Top end is new and I have replaced seals and done a leak down test.  The bike pass the leak down test with flying colors I don't even think it dropped a psi.  Once the powerband hits it hauls a$$.  Seems like my pilot jet is wrong, but it is stock and my plugs are black.  only mods are fmf and  k&n filter with lid cut in half.  

Could someone please point me in the right direction.  I feel that I'm so close.

Your vid did not work for me but I will mention that you really need to first focus in on getting the carbs balanced or sync'd perfectly before you even consider your jets.  I have seen all sorts of ridability issues from that.  Once you do that, you can usually adjust the air screws to determine where to go with the pilot jets.  Obviously if you run them out to 3 turns out and it runs better vs .5 turns out, you know the jet size may be a bit big.

okay I think I may need the carburetor sync tool.  I have the tors.  Its a pain to adjust these carbs with the tors.  One carb slide moves up and down and the other barely responds with the the big flat head screw

You can actually get it extremely close without a sync tool just by measuring and checking.
