Would this cause it? It looks like there's plenty of tooth left, IMO. :sarcasm:

its because you have a dime in the way of the chain!! remove dime and it should be good....

also, you might wanna re-install the chain onto whatever it belongs on, i dont think it will run very well without that sproket.... and the chain has nothing to grip either

I don't want to post misinformation, so i'll ask, could it be possible that a bad rear tire alignment could cause this wear?

And what kind of bike is this from matt?

^ lol, as far as I know.

I took the bike in around 12k miles and they said it needed a new one... 4k miles later, I changed it. Went +3 teeth and it's a lot funner.

Well... the front sprocket can't really move, as that there's a transmission attached to it, which is probably part of the motor's casing anyway, which is part of the frame...

So, the only thing holding the rear sprocket at a set distance is the chain tension adjuster bolts that push the rear axel back in order to tighten the chain as it wears. I don't know if vibrations can cause them to loosen off, though it is something you should check every 500km or so. Chains stretch alarmingly fast towards the end of their life... the first half of the adjustment takes a hellofalot longer than the last half, IIRC.

A chain long past its day would, I think, skip like a mofo once you run out of tension adjustment to make up the difference (or forget to tighten it often enough towards the end of its life). Replace it and watch your chain tension like a madman, and if it skips again, then you know it wasn't just the chain.

my 2 cents, anyway... Hope it helps.

common myth #1: chains stretch....

well no they dont....not even a little bit....but if you dont maintain a chain properly the seals and bushings wear out causing play....that play over time can make the chain longer but not "stretch".....

and fyi the proper way to adjust a chain is with the persons weight ON the bike so it compresses the shocks....

have fun and keep your chain clean and do not over lube!

I come from a land down under
You need to replace both sprokets and the chain at the same time as they will wear as a unit.

I've heard of people reversing the chain half way through it's life to get a little extra out of it but have never done this.

Worn chain on a new rear sproket = dead sproket in 5000+ Km's in my experience.

"that play over time can make the chain longer but not stretch"

http://dictionary.reference.com/browse/stretch

Waaaaaiiittt a second... so... over time the chain gets longer but it doesn't stretch? Now, before I go arguing semantics, I think it's assumed we all know that the metal tabs that make up the chain's structure don't stretch. It seems fairly obvious that the metal isn't what gets longer. If they did stretch from use, a sudden jar would snap it, right?

I can't say I know what you're trying to say here GV85: "chains get longer as they wear out the seals and bushings due to use." Isn't that saying that they stretch, right? Like, a 36" chain new, after 5000 miles was now 36.5", would mean it stretched 0.5"? Regardless of what component(s) of the chain got longer, it's still longer, right? Meaning it stretched, right?

Anyway, a good article on how to adjust the chain on my VTR1000. http://www.sportrider.com/tech/146_0010_handson/index.html

I've always been told that chains and sprockets are a wearing item; like brakes. There's things you can do to make them last longer, but they will eventually need replaced. I'm gathering that you're implying that a chain can last forever if one maintains it properly?



Yeah, agreeing with IJ... one must replace both sprockets with the chain.

Suzuki recommends my chain is adjusted with no rider weight on it, just that its on its side stand. Also Ive never herd over lubing is a problem, it will just fling off and make a mess. Id rather have too much lube flying off than not enough on my chain.

Too much wax maybe. Ive always read/been told that too much chain oil will only fling off, taking any dirt off with it.

you are wrong....

Talk to people who sport dirtbikes...they can teach you a thing or two!

Whenever I worked the chain on my quads I would let them soak in solvent then scrub them with a chain brush....then oil it with chain oil...then wrap a clean rag around it and pull the chain threw it wipeing most the oil off..

In the 4 years I owned a Polaris trailboss I never needed a new chain or sprockets.

Ok, well care to explain why too much chain oil on a street bike is bad then? Other than the fear of it collecting debris which I think isnt an issue. The first time you spin it up to a decent speed any excess will go flying off. At least thats from my experience and from the well informed people I know.

I lube my chain when its warm, usually after I ride I pull in and spray some lube on it. Throw it on the center stand and turn the wheel by hand to get the full chain. I clean it as needed or when I wash the bike usually.

Note that it is virtually physically impossible to over-oil a chain (since excess oil will be flung off), but it is possible to over-wax a chain.
