Topic: chain replacement

[joeson]

hello all, my 78 750k630 0ring chain is stretched. in sections it is loose and others too tight.I have cleaned and lubed with assorted penatrating oils and chain/gear oils and ultimitley was able to split the differance with modest improvment in the tension .the sprockets appear good with no noticable wear differance.Replacement of my chain is priority but is it really nessasary to replace the sprockets considering the local shop sells used sprockets with new chains as a set..for more $$ As well I have a soft link and plan to replace the chain myself you know my baby and all nobody touch.

Do u need to replace both sprockets and the chain in all one shot ?

[jalfonso]

I replace everything as a set.  New chain, new sprockets. 

Ride Safe.

[joeson]

I dont see why to replace my sprockets other than from what I have previuosly read here that all should be replaced as a set.. I just need to get a new chain from what I see on my bike unless I am missing something my sprockets appear good  worst case by replacing the chain only and the sprocets are worn could I not replace them later if not run too much ..Lots of rainy days lately and not much good riding weather left I will have all winter to spend time and money and not ride then

You need to explore the possible problems here.  You're assuming that the chain is at fault, but it COULD be the sprockets, although not easily visible.  Rotate the rear wheel, and make a mark some where on the rear sprocket and corresponding link when the TOP section of the chain starts to get tight. Rotate the rear wheel 360 degrees and see if the chain gets tight again.  If it does, your sprocket is out-of-round.  If not, the chain is probably stretched.  Not all sprockets are evenly hardened and may wear unevenly just enough to make a difference.

One option to consider here is converting to a 530 chain and sprockets.  Costs much less and is at least as strong as the old 630 chains.

I will use the advice here and make sure before throwing good money after bad. Thanks for the replies.Time to park the bike for the season as much work is needed other than this to be ready for my next journey safely

I would replace both sprockets if you are going to replace the chain.I have run 530 o ring on both my suzuki and k5 with no problems



My 2 cents.

just replaced my 630 chain this year
if your sprockets are good just do your chain
 my chain was old and dirty with stiff spots too
now its smooth as silk

If your sprockets have NO visable wear on them, they are OK.  If the teeth are chipped or worn at all, they need to go as a set.  No sense in buying a new chain to have it eaten up by beat up sprockets.

Replace the chain and the sprockets as a set, always.

What exactly is that, and how does it work?

[RyanLilly]

Why do many people like the scottoiler so much? Don't out bikes already have an auto-chain oiler from the cranckcase oil? at least my K4 does, it seems redundant to add a second oiler, but Ive never used one, so I cannot judge the merit of this product, I would just like to propses this question to those who have.

never used a scottoiler myself, just good old chain wax.  For a laugh, my boss uses white lithium spray on his Shadow's chain.  I know it could probably be argued that white lithium is great, similar to chain wax or other chain lubes, etc.  BUT I have used white lithium (spray and otherwise) in many different applications and found that it's great; if you don't want it to stay for a long time.  It'll stay forever, say on the outside of a hood hinge or inside a door jamb, but in between moving parts it just doesn't seem to want to 'stick around' HAHA  I figure if it won't lubricate a door hinge on a car longer than 2 weeks, it can't do much on a motorcycle chain.

OK my 2 cents  the auto chain oiler in my opinion and many others was a  blind buck     bad eye deer  lol little humor anyway I dont want motor oil on my chain for the most part it wont stay I use a cobo sometimes oil wax sometomes PJ 1 the stuff that STICKS and I allways put it on with the chain warm right after a ride now as far as the tight loose I this late in the season would put just a chain on IF you want to stay with the 630 if you want to go with 530 O ring of coarse you gotta change all thats what I would do is convert to the 530 Oring and the Oring is the key good luck seven fifty four ever  Craig up here in deer country Maine

At risk of, whatever, let's just say that this discussion has been around and gone around several times over the last few months! ! Being the great fan of the KISS principle that I am, I like the automatic chain lubrication idea because apart from keeping the reservoir topped up, it is one thing less to have to think about. And the chain needs less adjustment.

[dpen]

Simple equation

replace chain = replace sprockets (always)

[nteek754]

Hey all I run a 530 Oring chain and hadnt had the new set  sprockets and chain on my 73 750K for very long  maybe few thousand miles and  all of a sudden I had that  tight loose tight loose  well I replaced just the chain and let me see its been  well 6000 mile this past summer and 8000 last summer and  oh who know how many  3 summers ago but you should get my point  there was nothing wrong with my sprockets (in this particular case) glad I didnt hang them up in the garage good luck with what ever you do with your issue seven fifty four ever  Craig in Maine

[Loudpipe]

People go a little overboard with the fanaticism of replacing both chain and sprockets at the same time.  It's just like cam/lifters in an engine.  If one is visibly torn up or worn badly, they both MUST be replaced at the same time, or they will eat each other up very quickly.  However, if you can't detect any wear, there is no reason to replace the unworn part.
