My chain is stretched on my 1979 CB 650. I bought a new one online, but
since I could not find exact replacements for the OEM specs I thought I had
figured out one that would apply -- I read as much about it as I could find
online and waded through the multitude of chain choices, but I obviously
still lack understanding because I think I bought the wrong chain and am
lost.

The manual calls for RK50NK or DID 50HDK, 102 links, but I could not find
even a mention of these anywhere. I bought a 530 Heavy Duty 110 links from
jcwhitney, the only one I thought I could figure out. I began to work on it
and found that the chain on the bike has no master link. From what I read
these may not be interchangeable so I need advice. Thanks,

frog

A 530 chain seems to be the right size, but a Google shows the number of
links quoted at 102 or 106 according to model (I even found a 104 link
spec). With 110 links, you haven't got a problem, anyway, because you
can just remove some links.

OK, so your bike has an endless chain fitted. Again, not a problem.
You'll need to buy a good quality chain riveter/splitter and a soft
rivetable master link.

Break the existing chain, attach the new chain, roll it on, and loosely
join the ends using the master link. You'll soon see how many links you
need to remove.

Alternatively, take bike and new chain to a dealer and ask the dealer to
do it (cost: rather less than a quality riveter/splitter will cost you).
Oh, and ask dealer to source and fit new sprockets at the same time.

Given that you seem really ignorant about this most basic of tasks (no
offence), getting a professional to do it would seem wisest.

Your Honda dealer can't supply one? Yes they cost a little
more but chains last a pretty good while.

Not ignorant about mechanics, I have fixed chains on the interstate with a
flashlight and using a highway marker as an anvil. I can fix CB 350-450
bikes on the highway with my eyes closed. It is my first CB 650. I am happy
to know that the only difference between the chain on the bike and the one I
bought is that the second has a master link.

I will make it a 102 link with my Dremel tool, and use that as well to get
the rivet chain off the bike. I was under the impression that the riveted
ones were a different pitch, i.e. 630 instead of 530 that's all.

As for sprockets, this bike has only 8K miles on it, ridden 234/miles a
year--the sprockets are like new.
Thanks,

frog

My 1986 GSXR750 had a 50-series chain, which was the same pitch
(5/8th's between pins) as a 530 chain, but had slightly thicker
sideplates.

I bought a 530 Heavy Duty 110 links from
> jcwhitney, the only one I thought I could figure out.

If it's not a self-oiling (o-ring) chain, you should return it and
order an RK o-ring chain, because the o-ring chain will last 2 or 3
times as long.

When you get your o-ring chain, you'll probably get a 530 rivet type
masterlink intended for o-ring chain and you might have to order a
clip-type masterlink if you like to remove your o-ring chain for
cleaning with kerosene.

Problem with a rivet type master link is you need to buy a riveting
tool.

I don't immerse my o-ring chains in kerosene, I just wipe them off.

So I use the clip type masterlink with a drop of red Loctite on the
master link.

The side plate and master link has to be degreased with gasoline or
methyl alcohol so the Loctite will stick to the parts.

Then, when it's time to replace the chain, I grind the ends of the
pins off of one link and pry the sideplate off with a screwdriver.
