New chain and sprockets for my 73 cb500 K2
« on: July 23, 2008, 05:06:24 PM »
I am getting ready to order new sprockets and chain for my bike. I have read several posts on the topic, but I am a little confused. I want to stay with the stock 17/34. I have read that O-ring chains are great but that they have a tendency to chew the side covers up, is this true? What do you run in your bike? Any suggestions on this subject would be helpful, as I would like to get a good quality chain, but I don't want to damage my bike.

Thanks,

Brandon

Ah search engine phobic, eh?

The stock sprockets don't leave enough clearance to clear the extra width of an oring chain.
You can modify and shim the front sprocket to gain clearance.
You can use a 520 oring chain and sprocket instead of the 530 type.

You can use a standard 530 chain and sprockets as Honda delivered.

Not phobic, more confused  ;D. How does one shim the sprocket? Sorry if this is a dumb question.

Also, where would I buy just a stock chain? Seems all the chains I see are either X or O-ring. sorry for the stupid questions.

loudfastugly.com (if he has any left), or montecdirect.com, just to name a couple.  These two have the best prices I've been able to find.

TT, sorry if this is a stupid question, but you said I can use a 520 chain and sprocket. If I do this, do I need to do any shimming or modifications, or just get a 17/34 sprocket and 100 link chain?  Thanks guys for all your help, and sorry to ask such noob questions, just don't want to do this wrong.

Thanks,

Brandon

Is a shim just basically a washer or something used to space the sprocket out further from the engine so it doesn't gouge it? (sorry, this just dawned on me  ;D )

Thanks,

The 520 oring chain is about the same width as a standard 530.  The sprocket teeth are narrower necessitating different sprockets to match this chain.
The link pitch is the same (5/8"), so chain length is the same, if you use the same sprocket tooth count.

I favor the stock sprockets, as they are beveled so as to be quieter running.  I also use the standard 530 chain, which really ought to be available at any decent motorcycle shop, including a Honda dealer.

If you can't live without an oring chain, then have 1/8 inch milled off the outside of the front sprocket, and then add 1/8" shim on the engine side of the sprocket.  The shim isn't strictly necessary, as the sprocket is held in place by the stay plate, though it may help reduce spine wear.

if a 520 sprocket is made properly it will fit with no mods.you can find a non o-ring 530 at any harley shop or catalog.

I am thinking in a non oring chain is good enough for TT, it will be great for me  ;D I assume it just means I need to be sure to clean and lube it regularly.

What is the advantages of an oring chain over an non oring chain? Are they just quieter and hold oil better? Also is it ok to use a lube that was made for oring chains ok to use on non oring chains?

Thanks again everyone!

O ring chains are greased by the factory at the pivot points and rollers.  The orings retain the grease and keep dirt and most solvents out of the greased area.
Oring chains eat up some horsepower from the motor to overcome the resistance in bending the chain due to the tight oring fit, and their extra weight from longer pins.

Standard chains need the lube in the rollers and pivots renewed periodically, due the centrifugal force flinging it from the chain, and the ingress of dirt, etc. into the non-sealed area.
These chains can also eat up HP if the chain is allowed to dry out, making the chain pivots stick.

Rust will destroy both chain types.  Oring chains often use a chain WAX to keep them from rusting.  If applied properly, fly off is minimal.  But, wax provides very little lubricative properties, which it doesn't need due to the sealed in grease.

Oring chains are favored by those who do not wish to spend time maintaining the machine, or cleaning the lube fly off from the motorcycle.

A standard chain needs a penetrating lube to get into the pivots and rollers and then dry to a tacky grease-like state.  Application technique/prowess determines the amount of fly-off and subsequent cleaning of the motorcycle.
I have found that PJ1 chain lube (black can) has the exact properties needed to give standard chains very good life spans.
You apply this at the end of the day's ride when the chain is hot.  I place a newspaper under the bike while it is on the center stand.  The spray nozzle goes on the sprocket side of the chain, but where it is not making contact with the sprocket.  Rotate the rear tire while spraying the lube.  One pass for the right side link pivots, another pass for the left side.  The trick is to regulate the spray nozzle delivery so as not to over-apply lube, as the can will easily deliver product far faster than what is required.  Still, I get a few drips on the newspaper.  Clean up the paper and put both machine and lube away for the night.

The next day or evening, there will be some fly off, provided you have over-lubed, (and that is the side I err upon).  Some mineral spirits and a paper towel, easily cleans off any flung lube, quite easily.  I let the lube fly-off do the chain cleaning, so I seldom clean the chain, per se.  Only when I notice a particular build up that hinders accessing the pivots and rollers on the chain.

Here in California, I did this weekly or bi weekly, depending on if the chain looked dry, or not.  If the rollers start to "clack" when manipulated with the fingers, it was definitely lube time.  Of course, rainy weather would require more frequent attention.

Don't let the detailed description put you off.  Once you get used to the procedure, the chain lube routine takes 5-10 minutes, including clean up.  Still, even that amount of attention steers many people toward oring chains.

If the oring chain lube you have selected in simply a rust preventive, it is unsuitable for a standard chain's longevity.  It's likely better than nothing, but the rollers and pivots will certainly wear faster.

Cheers,

Ditto. I wiill just stick with the standard chain. Heh, probably shouldn't admit it, but I am just gonna have the mechanic change my chain and sprockets this time while he realigns my front end from the steering stem bearing and fork seals change. I am just too burned out from everything to try it myself. After this, just about everything that normaly wears out will have been replaced.

Thanks also for recommending a chain lube, that will keep me from looking at all the claims on the cans and wondering which ones actually work. Part of owning one of these classics is a little extra maintenance, so no biggie.

Thanks again a bunch,

Brandon.
