chain replacement

OK. I'm sure it's been covered at one time or another. I am not talented enough to find it, or too lazy. So, I will throw this out there to the best collective Strom knowledge base I know.

I have 20,000 Mi. on my chain. It seems time to replace it. I now have to adjust it about every 400 miles. My question is this: do I need to replace the sprockets as well? I have been told that sprockets should be changed with the chain by some. I have been told by others that if the sprockets look good, just replacing the chain is OK. The sprockets look good. I don't see any significant 'saw blade' effect. What do you fellas think? As far as chains and sprockets go, are the OEM sufficient, or should I look at some other brands?

Thanks for the help, boys.

Does anyone just flip the front sprocket over to put wear on the other side of the teeth? The rear would have to be shimmed if it is flipped over, and can that be done successfully?

Probably,y not a good idea, because of "sympathetic" wear. The chain and the rings wear together in a specific pattern.

I have three used 15T's, and one 14. I'll be flipping them because I don't buy into the "replace chain and sprockets as a set" mentality.

Look for excessive rounding, damage and bent teeth. The best way is to compare it to a new one. I get about 14-16k out of a sprocket and chain. They can go longer , and I maintain them well too.

Don't be a beancounter.

My Logic:

Of the total purchase, the cost of the chain represents about 75%, sprockets 25%.

My first question was: Based on the reasonableness in the price of the sprockets, if you didn't purchase them, and it resulted in a reduced lifespan of the chain, would I be money ahead? (A: maybe, barely...)

2nd Question: Based on the mixed information I was getting on this and other forums, could I really exclude old sprockets (regardless of appearance) as a potential premature wear agent of the new chain? (A: no)

3rd Question: Was there a good chance my bike would just work better with new sprockets. (Probably - at least statistically much better than not replacing them)

4th Q: If I didn't order them, and it turned out I should've, and then had to install them later like I should've in the first place, would I be pissed at myself? (A: yes. I hate doing shit twice, especially if I have an inkling that I should know better to begin with...)

5th Q: If I didn't buy them, am I just a fricken beancounter instead of a motorcyclist who lives to ride a mean machine. (A: yes - and I'm on unemployment!)

I chose to just buy them. I just want my bike to work right, and maintain it the best I can with the limited money I have to do so right now. The sprocket value equation made sense to me.

If my arguements for replacement make sense to you, I suggest you email Blair at SV racing parts. He'll hook you up.

Old sprockets can damage a new chain in a hurry. It's not a big expense to replace sprockets. Change everything at the same time and save yourself some trouble later.

A competent bean counter would recognize this as "penny wise, pound foolish". You shorten the life of the new chain by not replacing the sprockets, which increases the cost of the chain; and you haven't factored in the increased labor to go in there more often. Even when you're unemployed, your time is worth money (because you could be spending that time some other productive way, even if that just means looking for something productive).

Just my opinion and big-picture experience.

If you are going to replace chain and sprockets anyway, consider upgrading to a 530 chain for much longer life (so I've heard ... testing now in progress)
