Updated update on my hesitation problem. Besides all the other stuff I checked that I listed in the other thread, I visually checked the gas cap and it was as clean as a brand new one so I doubt that's the problem. I did clean the screen and bowl in the petcock - just a dot of dirt, everything else was perfectly clean. Ditto inside the carb - everything was spotless EXCEPT the pilot jet had a small blockage which I was able to clean out with a piece of thin wire. Could a partially clogged pilot jet cause problems at wide open throttle? It would generally run good except in 4th and 5th gears at WOT. I also noticed that partial throttle response wasn't what it used to be either. Before I button things up I would like to get your thoughts.
