so i replaced my chain and sprocket about 8k miles ago and now it cant hold tension anymore, and the chain is kinked. im thinking that the chain tesioners are old and worn out, or is it time to replace chain and sprocket again? thanks

 

Time to replace the chain and sprocket.

 

Chains continually stretch over time and eventually when you have the tensioners all the way out it comes time to replace the chain. So yes it's common and it's time for that chain to go. As for the sprocket that should be fine. There is no reason other the complete disrespect of the bike that a sprocket would wear out in 8,000 mi. So unless your a hooligan I say just get a new chain.

 

Ah...replace the sprocket and chain together.

 

inspect the sprockets, if the teeth are jagged or worn to a point then replace them

 

Yes........always replace the chain and sprockets together. A bad chain will ruin new sprockets FAST.....and vise-verse.

Did you lube it? That should help the kinking problem. Did you change teeth size from stock? Seems like you went down one tooth on the front with a stock chain and the adjusters are out of room now..and it needs lubed.
8k is way fast for a chain/sprocket to be dead. 20K should be NO problem.

 

I agree. Are you sure you are getting the axle bolts tight?

 

so i adjusted the chain to get rid of some of the slack and it seems to be holding...ive been good about lubing it but not so good about checking tension...so that could be my problem. the thing is i took it to a shop to get it tightened because i didnt have my tools on me, and they started filling my head with stupid sh-t that shops always do like i needed to start replacing stuff. im gonna see if my chain keeps tension, and then think about replacing the tensioners on the swingarm, or should those be totally fine after 23k on the bike? thanks again for the help.

ps-i replaced the chain and sprockets 8k ago and went with -1 front and +1 rear and 525 conversion and cut my own chain to fit.

 

525 conversion? It comes 525 stock. Unless it was already converted to 520 and your converting it back.

 

heh did i say 525? i meant 520...yeah thats right....cause i should know that
