sorry, now you should see it.

I would say that that front sprocket is hooked and there fore needs replacing sharpish.

Man of few words, any chance of a bit more detail, we can't really look at a sound?
Although first impressions would indicate a replacement chain and sprockets wouldn't go amiss.

It's also very clean looking in there, do you lubricate often Yamasaki? A dry chain will certainly sound clunky.

Re: Chain noise loud, Is it time for the replacement of this sprocket set? - yamasaki - 31-03-16

I have lubricate it often, but it getting more noise this days, So I decide to open the sprocket cover to check it out, It seems it's the time to replace it.

I think you do right Yamasaki  Smile

You can *see* the front sprocket is hooked! Replace both and the chain right away  :eek

I looked at that a few times, but i reckon that's a strategically placed dollop of chain lube.


How can it be hooked in the wrong direction, it's the front sprocket that pulls the chain, rather than the chain pulling the sprocket?

It looks to me like the hook tips are pointing forward, the normal wear pattern for a front sprocket.

Really?
Well I've learned something new today, although I've not really put too much thought into it before to be honest. I just see hooks and presume it's fooked.  :lol

At the bottom of the page on this link is a handy way to check the chain wear:

I recommend using a 1/8th inch drill bit as a gauge. If you can insert the bit between the chain and the sprocket while the chain is under tension, it's time to replace it. I would not wait until the chain can be pulled back enough to see the tips.

Correct that the front sprocket is pulling the chain,the sprocket rotates in an anticlockwise direction to drive the bike forwards, therfore wear on the sprocket will be on the right hand side of each U or trough  of the sprocket......so if the hooking is on the right hand side of the U....... as per pic and hooks are pointing towards direction of travel (anticlockwise) as per pic.......then that sprocket is knackered and a new set n chain is definitely needed!!!!

Sprocket Focced, :eek replacement definitely recommended and most likely the chain and rear sprocket also.

I think that yamasaki is really one of us and its a wind up

Front sprocket wears faster than the large one. Worn sprocket makes the chain wear faster. Since front one is not expensive, I'd change it "half way", without changing anything else, before it gets too worn.
