So yesterday I adjusted my valves with the engine dead cold, was triple sure about respective cylinders being at TDC, checked the rocker arm endplay, and then did a throttle body sync after a short ride to get her up to operating temp. Went for a longer ride today and after stopping for lunch, upon startup I heard a fairly loud clicking / cracking noise mostly from the right side of the bike. There were no issues in starting the bike and upon idle and thereafter, no clicking or cracking. Stopped after about 15 more minutes and started her again with the same sound, which again went away after starting. It almost sounded "electrical" like a spark gap - or like a piezoelectric start on a Weber grill. She runs smoothly and I checked the plugs yesterday (appearance and gap), everything seems normal (although I might have got some anti-seize on the electrodes but I tried to wipe all of that off). I have been starting her once a week as my seat was awat at Sargent for a month. No clicking sound until today. Anybody have this problem?
