Title: Chain and Sprocket(s)
Post by: CookieMonster on July 04, 2017, 01:48:16 PM
Ok so with 13K on the clock I went on one ride too long.

Two rides ago I heard my chain clicking a little and pegged it on the last wash I gave the bike and the lack of lube on the chain. So I got home, lubed the chain, checked tension and was good to go.

The bike spends in the garage when not in use (protected from the not so harsh elements), I have a clutchless riding style, don't pull wheelies but I think my riding style is to blame for this.

So the following day after lubing the chain I happen to notice that my chain was a bit lower than usual, checked the tension and the bottom chain reached the sss. I took a look at the rear hub to see how much room I had to play with and it was all the way to the rear...so I gently rode the bike home.

With 15T up front, 41T at the rear (which they both look pretty good), I wanted to keep the sprockets considering they look good and just going with the chain for now and upgrade to a QC carrier, sprocket cover and new axle nut set at a later day. The reason I say the rest at a later date is because I kinda damaged the sss with me not catching this in time and I'm hoping this is not as bad as it looks.

The question is...can I just replace the chain? I mean...the sprockets look good. What do you think? Who has done what I'm planning on doing before?

New chain is a good idea  [thumbsup] (was a while back too)

Sprockets are ok.

Don't ignore your chain in the future  [leo]

Awesome! So with that said I'm gonna go with a D.I.D 525 ZVM-X as opposed to the EK 3D I originally wanted to go with, that way the DID chain lasts as long as the sprockets have left in life...then I will upgrade all of the drive components!

Maybe one day I can powdercoat the sss to hide the chain rash it now has :(

My S2r carrier cush drives were smoke @ 13k.
Maybe give those a look too.

No offense... but it looks like you've spent a bit of money on your bike (judging by the bit of bling I can see in the photos,) and now you are going to cheap out on the cogs and accelerate wear on a new chain?

If you look at the bottom pic of your rear sprocket, notice how the bearing surface of the teeth (i.e. the 'back' of each tooth that the chain pulls against) is worn, enough that you can see it compared to the 'front' of the tooth (that does not see the bearing load the 'back' of the tooth does.)  Can you continue to use them?  Sure.  Would I?  No.

To CokkieMonster,

You listed Quick Change Carrier as your future shopping item. Just wanted to remind you that QC carrier has no real advantage over the stock sprocket carrier for the 99% of the street riders.

If you want it as a bling part, that's perfectly fine. (It is mostly covered by the flange, so it's not really visible, though.)
But otherwise, better to spend the money somewhere else.

Yep.  Even when you don't see wear you will if you hod it up to a new sprocket you will see a difference.  Always change the sprockets and chain as a set.  Well maybe not always but at 13K miles?

Perhaps, forget about quick change carrier set up,
(QC carrier $170 + Sprocket $59 = $229)

buy a set of new sprocket instead?
$35 for front + $159 for Supersprox Stealth rear sprocket =$194)


QC carrier

sprocket

Afam front sprocket

Supersprox Stealth rear sprocket
http://www.monsterparts.com/pc/736/Chain-Sprocket/736.html

You will save some money in parts price, you will also save money in the long run (chain will last longer).

Beside, like I said earlier, QC set up has no real advantage over the stock carrier.
(Even for serious racers, it really has no advantage. Look at Troy Bayliss's WSBK race bike. It's got stock style carrier set up.)

I see what you are pointing out...and I will keep the bushings in mind too. I guess you guys are right, money better spent on other parts other than fancy not so useful sprocket. So I guess that 3D chain is back on the list!  [thumbsup]

now...would anyone go as far as saying that I have compromised the integrity of my sss with that chain rash?  :'(

My S2r chain adjustment became oddly frequent (too tight, measured like the book says, too loose later), then noisy like a dry chain.
Reminded me of SSSA Honda Hawk ( critical chain adj) I owned.
Bingo, local shop did a oem chain, sprocket, cush bush, and the magic is back.

Nope, just cosmetic.

People still believe worn sprockets will wear a new chain faster than new sprockets? Lemme get this clear: I'm being told that brand new sprockets with a relatively rough coating that has to be worn off to make a smooth shiny surface wears on metal rubbing it less than a smooth shiny surface?

If sprockets aren't worn to the point you can see lines or ridges in them, they're fine to reuse.

OK, back to work. I hate the wiring I have to do on The Beast right now and need to quit stalling.

No, it's the distorted tooth profile of the worn sprockets that prematurely wears out the new chain.

I'd need to see proof, MCN-style. European Cycle Specialties about crapped themselves when they x-rayd my 916 rear hub because the excellent condition of my chain and sprockets. Was on 2nd chain and original sprockets at 40k miles.

But then again, my actual experience on my own hardware seems to often contradict "what they say", "common knowledge", and/or "what school taught me"...

Well...in any case I already purchased a supersprox stealth 40T 525 and have stayed 15T up front. Now since I'm playing with the drive, I am gonna do a few upgrades such as poly cush with titanium bolts, new sprocket cover and 3D chain.

A worn sprocket actually has greater bearing surface than a fresh sprocket, due to the 'cup' worn into the face of the tooth.  Also, a new chain on an old sprocket will still have to 'wear in'... just like it would with a new sprocket.

Looks like I'm a bit late, but here's my take based on my old S2R1000.

I went with the quick change. Not only does it reduce the rotating mass (the hub is aluminum) but it pays for itself on the second sprocket change. Also, I went with a 520 kit instead. The 525 is overkill for the DS1000 and the 520 stuff is not only cheaper, but weighs less as well.

Well...I wanted to go with the QC sprocket but the dollahs were a bit short and I could not pass up the good price I found this sprocket for. Currently waiting for the chain breaker, socket tor remove the wheel and carrier coming from Italy...or somewhere over the pond.

So after losing a few weeks of riding, the beast is back on the road.
