Chain.....bent?

So chain was a little lose ski tightened her up a tad. Then I started to hear a really loud popping, with a little tension. So I recheck chain more thoroughly. See attached pics.

Does that mean the chain is bent or the sprocket? I assume chain as that is only place it does this. Everywhere else is smooth when coming on r. Sprocket.

Help?

I can't see what you're trying to show in that pic. I can see that your bike looks neglected and the sprocket looks toast but it's hard to tell.

Judging by the pic, it looks like it may be time for a new chain and sprocket

the popping could have been your axle moving... did you remember to loosen the axle nut before adjusting the chain tension?

Time for new sprocket and chain. Hard to tell what the photo is showing. Doesn't look like it's been lubed very often.

May be out of alignment - rear wheel lined up with front, read up on the string method of alignment.

Sprocket is very worn and the lack of lube could make the noise.

When replacing sprockets it's time to replace the front and the rear plus the chain.

When you buy a new chain and sprocket (because you need both), please invest in chain lube/wax, mechanics towels and chain cleaner. Their are plenty of how to threads concerning chain maintenance. I hope the rest of your bike is treated better then your chain/sprockets.

The popping happens when your chain catches on the teeth of the sprocket. Since the chain has stretched beyond the chasmic grooves in the sprocket, the tendency for a smooth flow of the chain at all points may no longer be attainable. Thus, the chain catches in a misalignment and gives snap down into those worn in sprocket grooves.

Loosen the chain back to where it was before you tightened it and you should reduce the popping.

It looks like you need a new chain and should replace both sprockets.

Those are just speed gaps. Less friction when your chain isn't really touching your sprocket = faster bike



















In all seriousness....replace with a new chain and sprocket kit YESTERDAY!

Wow ouch guys.

Just a fyi. Bike has been sitting for over two years. Took it out last September 2013 for about 10 miles because I had just got it running after sitting since March of 2012 wreck. But far from completed. Then money tight so little by little until I was able to just recently get it actually moving. I had the bike running for about 5 minutes and obviously noticed something wrong with chain. Figured just tightening it would help. Then discovered the popping. I am far from a tech so I inquired TO LEARN.

Purchased new chain, f and r sprockets, chain lube, chain brush, chain breaker/press kit.

Thank you PhotoAl. I will check alignment as soon as I get home since I went and bought the new chain and sprockets I don't want the alignment to just kill these new ones.

Thank you Shoichiro - I really appreciate you taking the time to explain that to me. I figured I needed a new chain. But I wanted to know why.

Everyone else. - have a good day, appreciate the input even if negative.

We love happy endings.

We get bored, and you provided some comic relief. You are doing us a favor, allowing us to blow of steam. Think of how many puppies are saved by threads like this.

Take all the negative crap with a grain of salt. And think how many morons wouldn't have posted and just rode with it like that anyway. Even at the track I see bikes zip tied and glued together that I wouldn't touch with a 10 ft pole. Bravo for sorting it and taking care of your child!
