When to replace chain & sprocket
When to replace chain & sprocket
Hi all..I have a 94 cbr 900rr with 25K...it's the stock chain & sprock...how do I know when to replace chain? And sprock...my chain tension adjuster sq. nut has been adjusted back all the way indicating new chain zone...but still have lots of room left for hand full of adjustments. Everything works fine...I just want to know when to replace?

i would replace because if that is the stock chain then its over 17 years old. new chains are lighter and stronger and will last much longer and grip better. the indicator marks show when you need a new chain and it sounds like you do. stock is DID, i run a RK gold chain and steel sprockets and they are solid. check the teeth on the sprockets to see if they are worn down
Honestly, I think it's the stock chain? Is there anyway to find out??

maybe look at the master link. if it looks like its rolled like a machine did it on the assembly line, then it could be OE. just guessing though.
a new one will be lighter and stronger, but last longer than 17 years....lol. maybe.

Well let see....
When you've worn into the "replace chain" indicators.
When you can see visiable wear in the sprockets and/ or teeth.
When you start to feel roughness or tension due to the chain as the wheel rotates.
When you have 25k miles or 17 years on a set.
Any time your wondering if now is the time.
If you've never had a chain let go on you during a ride, trust me, you do not want to.
Always replace them as a set, for around the cost of a tire I can't imagine why anyone would push it farther than you need to.

I just inspected the chain, the marking say DID , japan, 520VM
Can anyone confirm this is stock? 17years oem? I purchas this bike about 3-4 years ago....the wear look ok? Nothing unusual?

You really wont know if its OEM
Doesn't matter really if you ask me. Depends how it was cared for and how the bike was ridden.
Lots of ways to tell to the experienced eye;
side to side motion in the chain
loose rollers
binding
sprocks and chain not meshing correctly
worn sprockets
I usually use DID xring chains with steel sprockets. Always replaced as a set. i can go into theory on this but no faster way to stretch a chain than to throw it on old sprockets...

if the teeth are very pointy then they are most likely worn out and will need replaces as well as the chain itself. chain from time will stretch. that will need replace too. go with aftermarket.
So these are few pics taken today....I tried to snap visible shots of the teeth....
Any comment appreciated?
