I Adjusted the valves last week, had 2 intake valves that was closed up completely and a 3rd intake almost closed, had a few exhaust that was loose, i set them all to 007 - 009 but my #4 carb is still coughing into the airbox, not as bad but it still does it just off ideal so I'm guessing i didn't get the carb ideal circuit clean when i rebuilt the carbs, it does start much easier now when cold and still runs very good.
I replaced the well seals but reused the valve cover gasket because it was still in great shape, i used black RTV with a high temp of 500f.
I thought the exhaust valves was the ones to tighten up but it seems my bike is reverse.
