Had my 97 zzr 1100D for nearly two years, no problems apart from routine servicing and part replacements, bike standing for past three months,on restart she was running on three, replaced plugs, one of which was oily, number 4, on restart engine sounded terrible, kind of clattering, pot four definitely not firing, has been suggested that oil ring on piston four has gone. Any other suggestions most welcomed. Made a twenty second video but haven't succeeded in posting it as yet, thanks. Chris.
