My 1982 GS1100 has a 630 (3/4" pitch) chain because chain
manufacturers couldn't make a chain with 10,000 pounds tensile
strength in 530 size back in those days.

My 1994 FZR1000 came with an oddball 532 chain, but OEM Yamaha
sprockets are too expensive, so I will order a 530 chain/sprocket kit
next time.

Blimey.

How does it run? I owned a CB650 a few years ago - the standard roadster
thing, not the horrible ShiteHawk semi-custom - and really rated it.

Only problem was it was jetted unbelievably lean - Honda fitted the
things with accelerator pump carbs, but it still ran lean. In the end,
after a series of plug chops, I went up two (yes, two) sizes on the main
jets and it was *perfect*.

Steered better than any other SOHC Honda four I've ever ridden, and I've
ridden them all except the 350, would hit an indicated 120mph, very
comfy, decent brakes, handled well, and was gratifyingly easy on juice.

Highly under-rated bike. I'm slightly jealous now.

Forever at the rate his bike has been used up till now... but why buy
a chain from a dealership? Sure, you can buy tires from a dealership
too, but why, since you can buy the exact same or better from any
other supplier at a cheaper price?

Plenty of mail order places are out there that can supply all sorts
of chains from cheap to expensive. I like Dennis Kirk, not the
cheapest but they have a wide selection, huge warehouse, and ship
instantly.

If you want to know exactly what chain, sprockets (teeth) and how many
links were on your bike when it was made, go to JT Sprocket's website.
They seem to have nearly every make and model (for any market) listed,
with all the correct specs. Not all websites are to be trusted to give
the correct number of teeth, etc., but JT has been pretty reliable for
me.

Note that chain master links are not interchangeable between different
brands of chain, something I recently found out- you have to buy the
master link that goes with your particular brand and model of chain.
Not a problem with the chains sold by DK, they come with a master link,
make sure you get one with a rivet-style link and not a clip link.
And DK usually have chains pre-cut to all the popular number of links
in stock so you don't have to do any cutting.

According to JT, your 1979 CB650:

JT Sprockets Catalogue
Honda CB650 USA
1979

Front Sprocket: JTF338
Teeth: 16
Rear Sprocket: JTR284
Teeth: 40
Chain Pitch: 530
Length: 102

Front sprocket available in: 16, 17 teeth
Rear sprocket available in: 37, 38, 39, 40, 43, 45, 46, 48 teeth

Thanks. Once I was made aware that the chain I bought would fit OK I
installed it, so I'm good for now. I will save your post and use those links
you gave for learning purposes. I know about Dennis Kirk -- I ordered a set
of tires from them at 7:30 PM and received them around noon the next day,
no express shipping or anything.

It's good to know about differences in master links according to the
maker -- mine came with one. The one problem I have with those riveted
chains is that I have had chains break on long distance rides -- the only
way to fix them was with clip master links so I would still be walking if I
needed a rivet tool. This is the first bike I have owned that came OEM with
a riveted chain.

Lack of maintenance or ham-fisted installation, probably. I have never,
ever, ever had a chain secured with a soft rivet break.

Spring links - yes, known it to happen.
