Hi, I have a 1983 CB1000 with the carbs from a 1982 CB900. It runs awful, and I was wondering if anyone out there can tell me if they are the same carbs, and what I should have for jets in it... so many jets.

I have a 1983 Honda CB1000; would not sell it for any money. But I will say the previous owner, who I knew, rejetted the carbs, changed filters, and tried to cure the cold blooded machine and failed terribly. I went back to stock everything, and it fixed everything hands down. I have my own mercury tubes for the carbs, and that's a must. Sorry I do not know if the carbs are different, but do stock, there might be a reason.

For all your questions about carbs and other CB900 or CB1000 questions, go to this site:


These guys share valuable information, there are databases, files, etc. Everything you need to find out how to do things correctly on these bikes. And if you can't find it, just ask, and Paul or Deano will give you the answers.

I have a question for all you CB1000 owners. I feel like a dummy, but I just bought a 83 CB1000 Custom for 600, and it runs good, but I was gonna change the oil, but can't find the oil filter LOL. This is my first bike and don't know a lot about them. Can anyone help me??? Please.

Any one tell me what years of Honda's you can interchange the front forks with?

I recently bought an 83 CB1000 Custom for $700. It is in great shape, but I think it has a burnt valve, is this worth repairing? The local Honda mechanic said I would be better off throwing the bike away if it has a burnt valve.

I just purchased a CB1000 and can't wait to get it going. I don't think the guy I bought it from realized what he had. This bike has been sitting for a couple of years, so I am in the process of getting it back from the grave. I am pretty sure I will have to have the carbs cleaned and jetted, and am not looking forward to the cost of it, but I think it will be completely worth it. Can't wait to get it out on the road.

To the guy who is looking for the oil filter. It is internal. If you go to any OEM parts catalog for this, you can see where it is located. I use either mrcycles.com or cyclepartsnation.com.

Does anyone know where I can locate a manual to work on this bike at? Thanks and happy riding to all.

For information and support on these grand old bikes (I ride 2 - black & brown) join the Honda CB900/CB1000 Custom Club.

Links to download manuals, common problem solutions, and 25+ years of experience and wisdom.

The CB1000C, unfortunately made only one year, is getting hard to find some OEM parts for - like pistons & rings. Still a great machine and good for 50,000 miles or more, when treated right.

Hello everyone,

I bought my CB1000 Custom a month ago. The previous owner clued me into a forum that has lots of good information:


It says CB750, but it is for all older Honda CB's. I have the original shop manual, but the guys on this forum really know their stuff and can clue you in to which parts are interchangeable with other models.

One thing I thought interesting was a guy that is documenting the overhaul of his CB1000.

I am 6'4" and weight 250 lbs. The bike is a stable, comfortable ride, but like others have said, it packs a punch when you want it. It is great for taller riders. I rode mine back to Alaska from Washington a week after I got it with no problem.

Safe riding, Mike L.

I also have a CB 1000. Trouble is, I have an ignition problem. I have power to the switch on the accessory side, but nothing on the switch side. Tried everything I know, but can't get it to start. I need some help.

To the person with ignition problem; had same thing, wound-up replacing the ignition switch... New key!

I'm the lucky owner of a CB100 Custom in Denmark, and I'd like to know if anyone knows other danes who have such a bike?

Hi folks. Just bought a 1983 Honda CB100 Custom, and I'm getting the engine repaired, but I'm having a lot of trouble removing the cylinder head; it's stuck, it's been sprayed with this 3M loosener, but it hasn't worked, and with the rubber hammer they're breaking the air cooling fins, and it's sad to see this happening. Can anyone give me any advice as per how to remove it gently?

Thanks from Guadalajara, Mexico.

Hi, I am looking for a head gasket for a 1983 Honda CB1000 Custom motorcycle. Would any of you happen to know who might sell them or know where I might be able to find and or purchase one? Thank you for your time in this matter.

16th Apr 2011, 23:17

How does one know if you have a burned valve? I'm looking to buy a CB1000 and I'm not sure what to look for.

30th Apr 2011, 16:44

Can you please explain to me how to use the extra shifter.. I almost died in traffic today because I stalled it out and couldn't find neutral. I have the 83 CB 1000c and love it, but it's confusing.. Thanks.

13th May 2011, 00:52

I recommend you keep it in "low" range for city driving... just use it as an over drive on the highway... that's it... so use low 5 for normal driving, then when on the highway, pull the clutch and kick her into the high.. nice cruising.. you don't have to use all "10 gears".

23rd Jun 2011, 05:56

You have got it. Take the low range in the city and the high on the freeway. I've owned my CB1000C for 14 years, never had any trouble. If I drive on a country road, I use the second gearshift to overtake. As you can tell, I live in Germany and have not seen another CB1000C yet.

24th Jun 2011, 04:33

I recently purchased a 83 Honda CB1000C, and the engine is falling apart from the inside, and I need to replace it. Anyone know where to get another one? I have been searching for days now, but all I come up with is parts sites and not total engines.

Also, would a CB900 (the predecessor 80-82) work in replacing it? Or would not everything fit? Please let me know guys, it's killing me as I absolutely love this bike.

31st Jul 2011, 13:04

I use the upper shift as a 6th gear, or just keep it in the upper position all the time.

1st Aug 2011, 01:42

I own a 1980 CB900C myself. Great bike, but I am looking for a CB1000C engine to put in it, because they are interchangeable; the only difference between the two is cylinder bore size. Happy hunting.

The transmission is a low/high range transmission. The low 1-5 is for mountain, towing, and the high 1-5 is for highway speeds. Technically, if you start out in low and shift 1-5 and split the transmission, you have high 5 and really only 6 usable gears. The ten speed transmission is deceiving. If you had ten gears in a single range, you could go 200 miles an hour!, in theory.
