Default Understanding Chain Spacers?

     

I wanted to start a new thread, because i really dont understand why i might need a spacer. It seems like using the spacers is something racers do aftermarket, because nobody markets chain spacers. What's the deal?

I've never heard of spacers either, not for your chain anyway, but I've seen a number of posts talking about a spacer with respect to 0@X type chains. People are saying you need to run "a Spacer" for these chains. I dont get it, what a sprocket spacer for alignment or something? Is this just some bs that is being tossed around or what? Like the dude who posted he was looking to buy a super powerband.

Hmmmm....I have never heard of a chain spacer either......If I took a wild guess I would just be pissing in the wind so I won't bother.

The spacer is only required on the CRF 450 and possibly the CRF 250 when running an O or X ring chain. It's only about 1mm thick and goes behind the front sprocket, but without it the chain will rub on the cases and eventually rub a hole in them- not a good thing! Fastway sells them I know, and Ironman sprockets come with a "spacer" built into the countershaft (aka front) sprocket.

Cool but if you spaced the countershaft sprocket out wouldn't it make the chain not run true to the rear sprocket causing accellerated wear?

It is only 1mm, that is a very small amount. I had to put one on my CRF when I went to a Renthal O Ring chain. Better that rubbing on case.

yikes, they dont allow o ring chains?

Are most of the honda buyers really not running o-ring chains? I'm suprised they would want to cut weight that extra little tiny bit, and sacrafice o-ring chain reliability.

Didn't you already ask this question???

I did not believe that I needed one and ran my O ring without it and it did rub. Now i have a spacer.

actually it's the same on all the hondas. the countershaft sprocket is very close to the case. if you run an oring chain ( which is thicker) it can rubb the case. a spacer is used to shim out the sprocket and keep the oring from rubbung.

you can also just flip the sprocket around and get the same result. honda makes the sprocket so it can be flipped . it has a shoulder on one side.

Yp, do you think it's by design to be done/used that way? I was under the impression that you certainly can do it, but it "shims" a little more then you normally want.

i've flipped mine for almost 8 years and had no problems.

i was told that the shoulder was made on one side so it could be flipped to accomidate the thicker chains.

it does not move it out much farther than the shim does, if any

I've used the spacer ring on my brother's '05 CRF250R before I switched him to non-ring chain but I didn't know about the shouldered CS sprockets that can be flipped. Thanks!

Hmm could this be a cunning way for old Honda to make a few extra bucks out of new cases ? Lol
