Chain making clanking grinding sound.

[LakeWylieJoe_imp]

My chain has 36,000mi on it and has only needed one tiny slack adjustment--it's still at the beginning of the green wear bar on the chain guard. However, it does have a few links which are slightly bound (kinked slightly) resulting in a periodic noise as the thing goes around. I did a short trip around the neighborhood without my normal helmet and earplugs setup right after my last valve adjustment so I could give everything closer listen. The chain sounded like a box of rocks ender certain throttle load--just awful. It's the chain for sure as the sound changes dramatically depending on throttle--wheel bearings would make noise regardless. The frequency of the crashing is consistent with a chain cycling, too.

I bought a new high end RK X-Wring chain and OEM sprockets, plus the RK tool which makes the pin staking Joe-proof. I'm going to swap the thing at my next tire change even though it shows no wear on the red/green wear indicator. It will be interesting to see what the front sprocket looks like. The rear one has no visible wear.

Have decided to just keep it lubed well and take it to mechanic when I get home in about 1400 miles.

You mean besides the tensioning it automatically recieved after every new rear tire installation.

Given that I'm new on the CB1100, I don't know what the chain and sprockets wear is like on this specific bike, I still find these numbers mind boggling. Normally I'd consider myself lucky if my chain and sprockets last 25000km, but usually around 20000 I will be almost at the end of my adjustment and sprockets would have worn enough to pull the chain up for at least 5mm by hand

Have I been doing it wrong all these years? I clean and lube the chain once week and when I wash the bike (except for that one experiment where I let it sit for 3000km untouched and it ate me up inside).
I am allergic to gunk on the chain slider and the front sprocket cover and I remove the cover and clean it up every week when I clean and lube the chain. Checking the tension is understood

Let's see what this CB1100 has in store for me, I've actually already ordered a chain and sprocket set just in case even tho my bike is only at 9000km

flint, I've had a couple of chains that make a horrible clanking sound as I take off. Sounds like it's hitting something. It's disappeared as I accelerate, but is very annoying at low speed. When it was doing it on one trip, I took it to a dealer I passed on the way and the mechanic had a good look at it. The tension was in spec, but he oiled it heavily and it stopped. The noise came back in time and oiling helped again.

zirconxi's insight is really interesting, although I recall trying to get it to make the sound on the centre stand and failing.

If you do find out what it is, please let us know.

For my case, to make the sound, I had to turn the wheel specifically in a bike reverse direction slowly so that the chain is pulling on the worn surface of the front sprocket. After a few turn once a while the chain will move/slip slightly on front sprocket due to the worn side of the tooth. This produce the grinding and clanking sound.
Turning the rear wheel as though the bike is moving forward will not produce the sound because the chain will be pulling on unworn surface of the front sprocket tooth, nicely seated.

Is chain wear worse in your Country because of sand acting as grinding paste ?

Consider a Forum search for, "Tutoro" - whether you ride in a sandy region or not.

I hate chain maintenance. Thus, I have not manually lubed a chain since 2014 and never had the need to replace chains or sprockets.

You'd think, but it's always been in the exact same spot with respect to the graduation lines on the adjuster brackets (three lines back, exactly).
