Shakey chain

[flamegrape]

I had my bike on a paddock stand tonight cleaning the chain etc. To shake off any excess paraffin and crap before re greasing it I slipped her into first and let out the clutch. The chain ran smoothly but at times started shaking badly. I shot a video clip of it to show rather than try to explain it.

The bike rides smoothly and I've not seen this before. Is this a major problem - or should I not worry?

Any info = much appreciation!! Thank you

My bike does it too when up on the stand. It's just because the idle speed varies slightly as far as I can tell. Only does it if sat on idle.

Thanks Noxious89123.
The ride is nice so I'm not too concerned.

Due to running on idle there will be times when the wheel is running a little quicker than the chain. What you are seeing is the chain being pushed rather than pulled.

Yup.

On another note, I hope your not cleaning the chain whilst it's in gear like that. *Que nasty photos*. I once pinched my thumb between chain and sprocket whilst turning it very lowly by hand. It hurt considerably.

Good good. Funnily enough, I was trying to be really careful, but was paying too much attention to my cleaning hand and not enough to my "moving the chain" hand.

If the WD40 can get past te O-rings, the chain is going to fail soon anyway.

Someone did a test on O-rings, using different chemicals in lots of little boxes and dropping a rubber o-ring in each one, and then seeing what the effect was on the rubber. The swelling caused by WD40 was in the range of ~0.02mm.

There are much better chemicals for chain cleaning though.

Yep the whole *gasp* don't touch a chain with WD40 is just scare story based on no real fact. The O-rings or X-rings should stop the WD40 getting past so, as said, if they do let it past then the chain is knackered anyway and so the risk is the same as using any solvent. WD40 doesn't damage o-rings either so that too is unfounded.

I think they may have been from a chain, yes. They were certainly that sort of size.
