I have got a stiff one

[fazersharp]

Chain link that is.I can feel it and hear it when the chain is under a low load at about 40mph, not coasting nor can I feel it under any decent load.I am not quite ready for a new chain and sprocket set so what is my best course of action-- slacken off wheel and set to work on the misbehaving link with two pairs of pliers and some engine oil ?.I did previously tighten the chain a tiny fraction so 95% of the chain positions would just touch the guide but then there is that one tight spot with the stiff link that is a little too tight. Should I adjust the chain to that one tight area and have the rest perhaps a little too slack like all the guides actually tell you to do  .

Is this the original chain?

Is it the rivet link thats tight. If it is, id be inclined to replace it. If not, try working at it

Yes -20k miles - I know its getting ready for a new set but the sprockets still look ok to me.

I have just been all round the chain slackened it right off to start and checked each one and there are more stiff ones than I thought - not super stiff but not so loose so that I can bend the links with my fingers if you know what I mean none were that bad but they all feel free now. But I still have a tight spot in the chain, must have an oval rear sprocket.
I did check the alignment with the two lines method a few months back and found the swingarm markings to be correct.
Going out now for a test ride

its the OEM chain from new so don't think it has one

Correction - its done 21600mls.Well the test ride showed a small improvement but still there at 40 mph 4k revs in 4the gear and 3k revs at 40 in 5th but only if I hold at that speed. I don't feel anything upto or over 40.
Now here's the reason I do not like scot oilers after using engine oil to work into the links

I doubt very much it will improve in my humble opinion, and 20 years out of a chain and sprockets ain't too bad.
Maybe you can save up and buy it a new kit for Xmas.

I get the yearage but not the mileage. Still don't get how a chain and sprocket set can wear so that you end up with a tight spot, all links are now free of tight links in themselves and yet I have a tight spot that I can feel passing over the sprocket or under it.
Its not the money so much as the time because I will be using a continuous chain so that is -- swing arm off but at least that gives me an opportunity to re grease all linkages but while the sun is shining -----

Just fit a split link chain.  Save you taking the swing arm out.
And fit a Scottoiler - saves you getting tight spots.
