old chain new master link?
 

I've brought a couple of new master links for my chain with the view to take the chain off and give it a really good clean more often.

It's currently fitted with a rivet link.

Now the fun part, my chain has worn a slight flat spot where it's run over the chain guide on the swing arm. will I be ok using fresh links on a chain that has worn like that? can I get away with filing down the new link to match? or just leave it until it's time for a new chain?

here's the chain, I took the picture when looking at something else but you can see the flat spot at the bottom.

My question the OP

Have you ever seen what happens when a chain lets go?

The lucky ones either flail off the back of the bike or jam on the engine sprocket the majority punch a hole in the back of the crank case,when you have seen the aftermath you buy new and change as and when messing about with such wouldn't even enter your head.

The replacement links are direct replacements for the model of chain fitted.

I was more thinking for giving the chain a deep clean to get more life out of it, but at present it is fitted with a rivet master link.

Yeah I've had a chain let go before which shattered the clutch pin and housing.

I brought a Scottoiler and it keeps my chain really clean, no need to remove it. Another option that I used to use is a chain doc https://www.youtube.com/watch?v=8A4yletZxOs it works really well for �20 you cant go wrong.
