Time for new chain and sprockets?

Scottoiler.

WD40 and WD40 Chain Lube are two different products. I would not use WD40 as a lubricant for anything as this is not its intended purpose. Personally after a long run I will clean off the chain with a rag and then apply SAE 90 gearbox oil whilst the chain is still warm between the plates and also between the inside plates and rollers, then wipe off the excess. This method has served me well for many years and keeps the chain clean and looking like new, as opposed to filthy and covered in gunk.

Chain lubewise, I've been using Wurth high performance dry chain lube for quite a few years now, no reason to consider anything else.

I use a Scottoiler with the dual dispenser tips to get at both sides of the sprocket & chain, but fill it with EP80w90 gear oil rather than Scottoil.
Keeps the chain beautifully oiled all the time, is much cheaper than using Scottoil and doesn't leave sticky gunk everywhere.
There is some oil flung around a bit that needs keeping on top of though, but is far easier to clean off than than Scottoil.

Adjust the Scottoiler delivery rate down a bit as it's thinner than the Scottoil.

PieEater's method is admirably detailed, diligent & no doubt the best for chain & sprocket longevity - but personally, as a lazy twonk, I use a dual feed Scottoiler!  :o

Had a short ride out on the bike today and I think the gear change is much smother and easier to use. Before with the old chain the gear change felt crunchy and not smooth,will need a long run to confirm.
I have noticed there seems to be a bit of a whine, but not sure where it is coming from.

The slight whine could be a sign the chain is slightly too tight. My old Thundercat used to do it after every service as my old mechanic seems to be useless as getting the tension right. Used to bring the back wheel in a few mm and it would stop.
