Hey all,
I came here previously for some valve adjustment insight as I changed out the shims to get the appropriate valve clearance on my 81 KZ50E. Prior thread can be referenced here..

So at this point the head has been put back together and the bike is up and running again. I am now noticing what sounds like a ticking sound coming from the #4 cylinder once the motor gets warm and stay ticking while hot. It started pretty much right after I got it put back together so I fear it's something to do with the valve adjustments that were made. For reference, cylinder 4 I & E both had extremely small clearance at the beginning of the job (.038mm each). After adjustment, C4 Intake is at .178mm & Exhaust is at .152mm clearance. The clymer manual calls out clearance from .08-.18mm so I felt like this was within spec.
I saw on another forum on here that some people were theorizing that the issue could be an exhaust gasket. I changed the exhaust gaskets this week and no change, the valve is still ticking. I recorded a video and uploaded it hoping a trained ear could take a listen and provide some more insight.

- dont mind the smoke, just a little bit of remaining oil on the cylinder from a prior oil leak.
Thank you!
