I am sure this has as already been covered but I couldn't find a thread. I rode about 300 miles today. Came home parked the bike to eat dinner. Went back out to put it in the garage and noticed a slight ticking coming from the valve cover area. Any thoughts or concerns. Changed oil about 500 mile ago. Honda semi synthetic.
My 2018 Goldwing tour also exhibits a fairly loud ticking noise coming from the right side (The left side is as quiet a a church mouse) starting about 3-5 minutes after a cold start. The noise seems to diminish somewhat as the engine reaches full operating temperature. I've checked the valve clearances and they are all in spec.
What side is the ticking noise coming from on yours? Most of the threads that I've read about this indicate that the ticking noise is coming from the right side. In my opinion if the left side does not make any ticking noises then there is no reason for the right side to tick either assuming that all of the valves are in spec. If you do a search there is a video that someone recorded and posted of the ticking noise on theirs (Right Side). Mine is not quite as loud as the one in the video, but it is much louder than what I would consider normal.
Years ago I had a Corvette that I bought new that had a loud tapping noise coming from the rear of the engine on the left bank. The dealer replaced the pushrods, rocker arms and lifters, but the noise still persisted. While attending the National Corvette Homecoming, I had the opportunity to speak with a rep from the Flint Michigan engine plant and he was familiar with the problem. He said that they had a batch of defective cams that were ground to the wrong profile and that was causing the noise. Once they sent the new cam to my dealer and it was installed, the issue was resolved.
I'm wondering if this could be the problem here???? It seems strange that the majority of users who are complaining about tapping noises are reporting the noise from the right side.
There is also 1 case that I am aware of where a valve shim may have fallen out on the right side causing "Catastrophic Engine Failure" as reported by Cruiseman on a friends 2018 Goldwing. There is a video that described the issue and a sound clip of the noise. He was going to report what caused the failure and what parts were replaced, but so far there has been nothing more on this subject.
