chain identification

[cornishsv]

I have a did x ring chain on my pointy sv that I'd like to take off to remove a link and to thoroughly clean and oil as it's been on the bike all year long in some ****ty weather. But I'm not sure if it's a 520 or 525 pitch chain to get a new joining link for putting back on, how would I identify which chain I have?

It is almost always stamped on the face plates of the chain. Usually something along the lines of "525 VM" or similar to this:

That should show what you have now. I'm struggling to think of a circumstance where removing the chain would be needed. I'd scrub it up using a toothbrush and some paraffin if it's in a complete state and re-oil with some clean engine oil and wipe clean to minimise fling. Removing a link would be a huge adjustment, so I assume you're considering replacing the Master Rivet link. In which case check this is still available, some older ones are not, and these are specific to each chain model.

Take swingarm off and do your bearings at same time

this. or just clean it on the bike.

its a bloody chain stop fussing. as long as they are oiled and or lubed regular then who cares what it looks like or do you have OCD :D

I wouldn't split a chain to take it off to clean it. Taking the swing arm out to service the bearings along with the shock and linkage bearings is a good idea, but a big job. If you just want to clean the chain and relube it I'd recommend Muc-Off chain cleaner, it is really powerful and fast working stuff. Spay on and wipe off and your chain will look like new.
