Recapping, for clarification, this goes back to your June 8, 2016 post regarding easy starting cold and hard starting with warm engine. I have just started having this same issue, so I am telling a bit of my story hoping you get something from it and, also, tagging along for whatever advice is offered.
My immediate suspicion was magneto problems, either a bad cap or LT windings leaking with heat. My cap is a new EasyCap, so that is very doubtful. To test the issue I went out for a ride that was long enough to warm everything up. On getting home, I immediately pulled the plugs and tested for spark across about a 0.150" gap. No problem leaping that gap. I also tested with the plugs that I had just pulled from the bike and the result was a good hot spark. Tested compression on both sides. All good. This was all just yesterday, so I have yet to check timing and look for possible carb issues.
