Hi I have a GPZ400R ninja1987 model the bike has a ticking sound coming from the head ,It sounds like a tappet but only one, the sound increases when running hot. I would like to know what is the correct oil to uses and if it is a weakness with these bikes Does it requires setting or replacement of shims or if these heads wear in the buckets or any info would be appreciated
