2005 cbr 600 f41 with 14,100 miles.
i just bought.
just cleaned and adjusted chain.
while adjusting it when barely into the "replace" section of the adjustment.

it there any other indicators to when a chain is becoming unsafe?

thanks for the help and sorry for my ignirance.
there are a few good write-ups on here on how...just need to know when.

 

i replaced mine when i heared the chain 'clicking as i push it into the garage.

 

As long as there are no kinks or tight spots and it seems in good shape, you could push it until you can't adjust it anymore.

 

thanks

 

when there are loose links, bound up links (why the click when rolling), play in the links, or wear in the rollers. maybe even all those things at the same time. if you remove the rear wheel and roll the chain around with your hands, it becomes obvious if its worn out.

 

Whe it comes to sprockects when uts showing lots of wear like teeth are not straight , not mych teeth

As for chain when it stretched so much that it can not be adjusted any more

Its also a good idea to check the chain once a week /fortnight depends on how much you use your bike to make sure that part of a link in the chain isnt missing and general wear and tair

If you meed any more advice just ask as I am a ex mechanic and help out at mates bike shop now and then espically this time of year

 

This! Also not sure if it was said already, but you should replace sprockets and chain at the same time, as they tend to wear evenly over time.

 

One guy i cam across uses ep80 or ep90 (gearbox oil) to lube his chain and after 3 years still has same chain and spockets but dont know what sort of mileage a year he does

It would be a messy job lubing chain with ep80/90

 

you replace the sprocket when you replace the chain. you replace the chain when it is loose and you can't adjust it anymore.

i use gear oil sae90 + drying teflon lube. i apply the gear oil with a toothbrush. wipe off the excess. spray on the Dupon to help the oil from flinging. it's been like 12k miles since I install the chain, and it has yet need to be adjusted.

 

I usually ride it until i cannot adjust it any more, in one case, when it brakes, or when i can hear it slapping around while im riding at 6k rpm and jardine exhaust!
