Chain/sprocket question
I have a rear sprocket with the teeth turned, a front sprocket also a bit turned, and an o ring chain that is great and on the 4th adjustment out of 9. Everything here is renthal. I wanted to know if replacing the worn sprockets fore this nice chain will lengthen it's life, or should i run the sprockets a few more months and then get a whole new setup, leaving the decent chain useless?

Grab and pull your chain where it wraps around your rear sprocket... how far can you pull it away from your sprocket?

1/2 isn't bad.... I'd buy cheap sprockets and keep running the chain and then replace the entire setup with quality when the chain is toast.

Yes... good quality for cheap! I love the Z-sprocket!

JayBird would give you guys such an awful spanking....WHERE is he when he's needed!!??
1/2"? That's past bad! The pitch on a 520 chain is 5/8"!!
Sprocket damage occurs when a chain gets to a 3% wear level. IF sprocket damage (teeth 'turned') is already present, the chain is likely well over 3%.
Your chain is not 'great'. What does that even mean? No bushings are missing yet?
Yes, you can put on a new set of sprockets. That will be a complete waste of money, but you can if wish.
When you get around to taking that chain off, measure 10 links (warm, clean, stretched) to any given 'same' spot..like the center of the pins. 6 1/4" is what you get with a new 520 chain. 6 7/16" is what you get with a 3% chain.
That's cheating. No fair saying YOUR chain is 6 1/4" just 'cuz you know that's a good answer!

CC... I've ran chains that would expose a tooth before that worked just fine.... damn KTM's! No binding, noise, bent teeth or additional stretching. How is this you say? I don't know... but it's the truth.

It's new.
Check THIS.
Cool, 'eh?
Exposing a tooth? Sounds painful!!
I don't know, either.
You can't tell a chain is worn out by looking at it necessarily. If the bushings are crammed by 1/2 shell bits into your CSS guard, the chain is probably bad. Don't ask how I know about THAT...I must'a read it someplace.
Measuring a given distance and comparing it to the known pitch will tell you for sure.
Maybe the punkin just din't have enough poop to sweep the sprocket teeth!

I only adjusted it and never really checked it since it was so quiet and the sprockets looked good. When the guy bought it... he loaded it on his truck and pulled on the chain and I couldn't believe my eyes.... He didn't say anything because he stole it from me on eBay. If he would of said anything I would have said your right.... I am ripping you off and gave him his money back.

Chains that have grown past their original pitch and bad adjustments are what cause sprocket teeth to deform.
Unless you measure your chain, as cc described, there is really not a good way to tell what condition your chain is in. Pulling it away from the rear sprocket is hardly adequate to tell when you are reaching a point that the teeth will see deformation.
Weathermen used to hold their wet finger in the air too...
It was your worn chain that wore the teeth of your current sprockets, as well as the next ones you run on that worn chain.

Anyone is welcome to run a chain as long as they like, over however bent-toothed sprockets they like.
Use some common sense in the matter. The size (pitch) of a chain is the measurement in length of a link. When you're dealing with what may be thousands of an inch in wear on a chain, you generally measure a LOT of links and divide by the number you measured to get the figure for 'a link.''
A 520 chain being 5/8" pitch (.625") there is no reasonable, logical or factual argument that says when that measurement reaches .640" that everything is fine. SOMEthing is worn, or, where did the extra distance come from?
The entire chain is made up of cylindrical parts...and that wear is NOT going to be evidenced by 'every thing cylindrically smaller (or larger).
If a sprocket NEVER wore, the teeth wouldn't ever pull. When the teeth DO pull (or get dished out) it's the chain that MUST take a beating every time IT is pulled on. It's got no support! ANY thinking that in such a case you can change part of the 'unit' without changing all of it and make everything 'fine' is simply silly.
I guarantee I run chains past when they probably should have been replaced. I have, also, replaced sprockets when they showed no obvious wear and chain 'stretch' indications were 'good.'
But replacing sprockets when the teeth are already pulled or swept..that is a waste of money.
But, you're welcome to it!!
