Yes, I knew better, but I did a short burnout on my 2001 Fatboy, that otherwise has had no mechanical problems since birth, and now I have a slight pinging type knock intermitent at low idle and when under power at the beginning of each gear shift. At regular RPM it is not there, just at idle and start up of each shift under power. Its coming from the front cylinder I think and it is not loud, but sounds like something has come loose and is clicking around in there. What could this be? It may be coming from the primary, but sounds more like the front cylinder. Amsoil 20-50 Syn. oil Any ideas?
