Chain and Sprockets?

I have a question!
I replaced my chain about 8-9,00 miles ago and I am all out of adjustment ability. So I know I need to replace the Chain, but my mechanic says that you have to replace the Sprockets with it. Now the last Chain I put on there was no mention of this(different mechanic).
The Sprockets don't show any obviouse wear, not even close to the cutouts in the Clymer book. Any opinions???
Or is this guy just yankin' my Chain?
Punn intended !!!

 

I have always found that it is good practice to replace sprockets when replacing a chain. Many of todays sprocket sets are aluminum on the rear hub. Aluminum has a tendency of getting brittle through many heat cycles. I have seen an old, but good looking, rear sprocket fracture. Engine cases are the same way, they too become brittle with age and through many heat cycles. Give yourself piece of mind...spend the extra 100 or so and ride with confidence.

 

You may not be able to measure the wear on your sprockets but they are worn to a certain degree especially if they are original and you have gone through two chains. The theory is that the new chain will wear out faster if it is run on old sprockets due to the fact that the pitch on your slightly worn sprockets is larger. Fresh new sprockets with a new chain will last two or three times longer than just a chain replacement. You are wearing them out fast if you are out of adjustment in 8k. A chain should go at least 25k with proper maintenance. Mine do and I'm not gentle on them.

 

Thanks guy's !!

Advice taken and I'll drop the "C" note !!!!

 

I have always been told that regardless how well your sprocket looks, replace them when you replace your chain. Both chain and sprockets wear together in a symetrical fashion. If you just replace the chain, the valleys and peaks of the sprocket will not mesh properly with the chain, thus will increase the wear rate several times faster resulting the need to again to replace the chain as well as both sprocket/counter sprocket. It is best just spend extra $$ now for better performance and longevity.

Hope this helps

 

Digging this one up

Did a search on this and this is the most recent post. I've got a 97 VFR and I need to tighten the chain and was wondering what are most people getting for chain life? I've got just about 15K and haven't touched it. Is this good? Bad? Thanks for the help.

 

I just replaced the original chain and sprocket on my '91. It had 31,000 on the clock.

 

Pin spanner?????

So I'm looking in my Honda Service Manual on how to tighten the chain and it mentions a Pin Spanner. Do I need this to tighten the chain? Does one come in the tool set or do I need to buy one? Any recommendations on where to buy one?

 

The spanner and handle should be in your tool kit. The spanner looks like a flat question mark, the handle is a tube with one end smashed so it fits over the spanner as a handle. I would think ther would be a picture of it inthe service manual.

 

Thanks

I'll look in the tool kit. Thanks for the help! I'm assuming by the other posts that with 15K on the bike I shouldn't worry about being out of room to adjust yet.

 

chain wear is extremely variable. weather, riding conditions, regularity of maintenance, type of maintenance, etc all play factors.
