How much chain stretch is OK?

the "correct" way in that picture looks like he's spraying lube all over the tyre, plus he'll only be able to oil one side of the chain.
The description is right in that you need to get the oil between the plates and to the pins. But I think you're better off spraying the oil on the upper surface of the lower chain run, just a bit in front of the tyre.

I just use cheap non-o-ring chains and they've lasted ok for me so far. I just oil it when the chain is starting to look a bit dry (I'd guess that probably works out to every 300-500km or so).

Nah, the swingarm has engraved markings on it - definately not moving.



Hmm maybe it was fitted with a dunger, so any suggestions for the next chain?

This link has some interesting tips - first thing I noticed is that I was not lubricating the chain as demonstrated in the diagram at the bottom of the page.

I'd ignor the "right way" the "wrong way" has worked fine for me in the past, just rotate the wheel backwards.

As for lubing I use hypoid gear oil in a 1 ltr bottle with pull out tube. Tip then squeeze the bottle so about 50mm of lub is showing in the clear tube. Spin the wheel whilst the oil dribbles on to the chain. usually once a week if fine. Every second day or at each refill if riding in wet weather. I too use so called "cheap" non o/x-ring chains on most of my bikes with absolutely no major issues what ever. Paid around $40 for the last RK 530 chain for the CB750 about 12 months ago.

I've done 29,000 km on my 1200 bandit,so far, with no appreciable wear on the chain.
I don't even need to adjust it when I change tyres,Maybe 4 adjustments in total.
I lube with cheap warehouse 20w50 motor oil and kerosene.

There's a reason for this durability.....
