Question Engine rattle

I have had no luck trying to find out whats causing the 5000 - 5500 rpm engine rattle. Talked with dealer 3 times they were supposed to contact Honda and get back to me. Dealer rode the bike and agrees it is noisey. Has anyone got any feedback from there dealer or Honda on this subject ???

Scrub the chain properly. Properly lube it with proper o-ring lube.

Test it again.

rattle

It's not the chains, so throw that out the window. I too have the same noise, but no word from honda yet. My father in law was an engineer by trade, and in discussing it with him he has hypothesized that at a certain RPM there is a point where the valve rockers are potentially vibrating on the cam. Very possible. I guess Honda will have to come out with an official verdict to put us all at ease.

I have done that several times. Thats not the problem. This sound for sure is coming from the top end of the engine

Strange I complained of this exact thing for months, as soon as I started deep cleaning/proper lubing the chain it amazingly disappears.

BTW, do ye guys always have it, or is there most of the time and disappears every now and again?

Sorry, it's a colloquialism, it doesn't mean to literally 'scrub' it.

I think I was the first person to complain of this noise back in January. For months it bugged me trying to find and solve it. Always at the same rpm 5400-5600. Sometimes gone, but usually there for around 80% of the time. Really annoying. Certainly doesn't sound like it's coming from the chain area. I even stuck clothe under the dashboard in February, but nope. It really does sound like it's coming from the top of the engine. The same as everyone else is now complaining about.

First time I properly cleaned the chain with a proper chain cleaner, and lubed it with a proper o-ring lube it completely vanished for a few hundred km. And has done so ever since, never returning for a long time afterwards. Which is amazing as the noise isn't coming from there.

Massive coincidence if so many other people have the same noise at the same rpm and it's something entirely different.


Strange that with all the experts that no one has found it yet. I mean the top of the engine isn't exactly massive.

Too high a gear on a single will cause chain chatter, or poor rear wheel alignment or a dry chain.. but we're a bit off topic, the OP is talking about an 'engine rattle'
i'd let the Honda dealer sort it.. they are ones that carry the 2 yr waarranty.

Seems many who have taken the bikes to them have had them returned with a 'it's a normal sound'. Which they haven't been happy about.

My bike's just had the first service including the valve clearances set to spec. I still hear the clatter on the freeway and I still label it as normal tappet noise as it happens in time with the revs (revs increase, frequency increases).
