Chain & Sprocket

[ScaredyCat]

Please forgive the n00b questions but I've just been out to my bike to start prepping to ride to work again, thought I'd start riding again tomorrow but judging by this I wont.

Started to clean the chain, noticed a few links like this:

They are stiff and don't show much sign of moving when I use my fingers. The chain 'jumps' occasionally as I spin the rear wheel. I don't mean it jumps off the sprocket, I mean it flicks up momentarily as I spin the wheel.

The chain was fine before I stopped riding, mid December. I lube it after every ride. What's the likely cause? The links seem stiff the chain is very tight, no slack at all. The bike has been on its centre stand (appears to have seized a bit too ) for the entire time.

Is the chain b0rked? This is what my rear sprocket looks like:

Is that ok (other than needing a clean) or classed as worn. Do you have to change sprocket & chain at the same time? Honda's quoted price for a sprocket and chain set is £184.14 then there's fitting on top, with a 1 hour scheduled time for the job. I need a new rear tye too


Subframe might be twisted but chain definitely not slack..

I'd oil it and go for a spin, see if the links loosen up.

You could try working the stiff links with some grease or oil and see if you can free them up but it's likely needing replacement.

For the figure you've been quoted to replace the set you could by a chain and sprocket set and a decent chain tool and do the lot yourself and then you'll save from each time onwards.

It'a a straightforward job.

That chain doesn't look good
NC700 c&S set not from Honda DID and JT sprocket from an independent £120 and 50 to fit

I give a a very good lub and see how much it pulls off the rear sprocket if not much ride it and keep it more lubed it will probable sort it elf out if not too worn

Sprocket looks ok to me.

Does the chain have a split link in it? If so I'd whip it off and leave to soak in a bucket of white spirit for a couple of hours then give it a good lube before refitting.

If you can't easily remove the chain then I'd do as others have suggested and just lube the hell out of it

The chain is dead, the sprocket is alright. Definitely check the front sprocket though.

Can you wiggle the stiff link with a pair of pliers? I'd get some thin oil on it, then wiggle the link to let it penetrate

try busters, they had street triple C&S kits on ebay the other day for £85 posted, or a chain for £75 and it was proper DID gold link stuff

Clean with diesel and it will be fine, I took my derbi chain from a right mess to very smooth with petrol diesel mix and a sponge.

Whilst some erstwhile members would suggest you make videos when you cleanse the rear end, may I suggest maybe laying off the soap when one is laying dormant for the cooler seasons? Keep your teeth and links nice and wet. I suggest this merely as your rear end looks ripe and clean for the summer. That chain is probably fine, dependant on your lubrication regimen. But, as always; replace C+S as a pair if chain fubar'ed.

TL;DR One minute ride around the block, lubricate, check function again after a 5 minute ride. You'll then know before you whip it off for a change of rubber.

BTW, tell Honda to fuck off re; labour, if they are changing the tyre.
Infact, diy. And lube it.
