Much unloved big brother of the 250 wet dream.
I had one at Meads when i worked there that holed a piston and needed a new generator assembly to cure it which was expensive, balance chain can be a bit of a pain and blocked carbs can be a real nightmare, localy the dealers used to send them away once for ultrasonic and if that didnt work new carbs

For some strange reason Bryan the Generator was totally different on the 400N but still unreliable and I remember my friends 400N CDi failing with only a couple of thousand miles on the clock. Funnily enough, like you said, the carbs too were problematic and the guy US cleaned them but still ended up getting replacements from a breakers. . Seem to be plenty of spares and groups around for the Superdream though (tons of them sold in the UK) . Rex's do replacement Cdi's and the alternator stator can be repaired (it's the HT/pickup coils that fail not the alternator coils themselves).
Bit of a Marmite one there Ted .... I personally prefer the CB250RSA single that was sold alongside the Superdream ...that's why I bought one to restore.
-
Mine was a great bike in doing what it should - and more when i tuned and raced it! A bit a bit characterless as standard. It just did everything well.
I had no carb or generator issues or any others not related to abuse.😱 I don't know if the later and rarer 450 version was more reliable with the generator etc. Basically the same bike in most aspects I think

I think the problems start when the bike is unused for a long period Tim...certainly the case with the carburettors ... my mates was bought new by a work colleague who did a couple of thousand miles and then didn't use it for years. He went into all of the dealers in Hull to buy a new 400F, as he loved mine at the time .... but they were all gone, so he bought a new 400N instead (salesman told him faster than the 400F .. not sure if that's true or not ;D).

Thanks for the information Guys - to complicate things a local 550 has come up so clearly I am still not sure what to buy next.
I liked the 250 version but back in the day I liked the idea of a 400 more. I am going to be sensible and not rush into anything - only definites are it will be a Honda with only 1 or two cylinders that will not break the bank with essential spares available.
I'm going to Stafford show with BiL next month so I'll see what floats my boat.

Look up CL77 (350cc) / CL72 (250CC) US soft off road look, raised pipe, lovely looking motor. I love them but not everyone's cup of tea!!
-
My main worry with smaller bikes is that my hip angle will be a problem as it is on the 400, the 500 is really comfy.
The reality is I've spent much more time restoring than riding so for me with my low annual miles it's pretty much irrelevant I guess.

Agreed it's a pretty bike the CL...... the engine looks lovely but in really is a bit of a pain in the ar$e .... OK it has ball races for the cams, which is great.... But the cam is in two halves and joined by the cam sprocket which incorporates the auto advance, which can be troublesome. A lot of the heads weep oil around the steel skull insert too. There are a total of 5 chains whizzing round but the biggest pain in the flimsy kickstart cover and its associated gears and bushes..... The kickstart kicks forward weirdly, at least it does on the CB.... plus the kickstart shaft runs in needle rollers through the gearbox shaft and when the rollers seize it whacks the kickstart forward. Latter is on the CB model though and may have changed on the CL. I rebuild one these engines when I was a 19 year old student but I steered clear when I got my current '66 CB72 and engine rebuilt by my friend Graham Curtis ... he does all sorts of updates/ modified assemblies/ crank rebuilds for that model. Not my favourite Honda engine though. The CB160/CD/CB175 engines are a peach of a design in comparison and lovely to work on.

I'm leaning towards a VT500e again...........🫣

That tidy 550 sold for £1220 .
The 400 superdream for £750.
-
I saw a very good one near Tower Bridge recently, the first in many years. I wondered if it was straight out the crate even. I had one as a first bike when I arrived back in England in 1982, I used it for dispatch riding and it could take it. Slipping clutch , wrecked cush pads and it had a raft of minor problems but it seemed to be cheaply constructed to me. I had to give up with it by 12,000 or so. I can't recommend one can I?
One man's dream is another man's nightmare, I'd rather stay awake and ride something else! ;D
-
Then again, now I've seen it, I had the 250 ::) Maybe the 400 is more of the same?
-
They are quite potent for a 400cc twin (i ride some when contemporary) with huge contrast to the 400 four in almost all respect.
I wouldn't count one out Ted. From memory, they're taller and more spacious than the four, with a bigger bike feel to the whole layout. The four being a very good miniaturisation in being so tightly packed into it's form.
Three valves per cylinder (Mercedes did this too) balancer shaft to mitigate vibration, 180 degree crank from memory, a nice running note to them with a "bubbly" overtone.
Comstar wheels that divide opinion, which I like on that period of bike. Not really able to true them generally so inspection should take account of that. The rims are really good quality rolled aluminium section with very good integrity though.
A good contrast to your current stable too, well balanced to moe around easily.
Perhaps even consider a CX 500 as very different project.
-
I had a brand new one in 1979…£939 on the road… did 24,000 miles on it in 2 years…and had no issues with it at all …. KLD 157V … where are you now ? 🤔
-
Last v5 1985 not taxed since sept 86
-
Either scrapped or sitting in a garage somewhere, I normally cycle though our estate every day and it's amazing how many open garage doors reveal bikes stored away within, mind you I have 3 in mine.
Cheers

I'm viewing a Honda 400N on Sunday that became available as e-bay sale fell through.
It ticks a few boxes as I used to hanker for one when looking in the dealers shop window when on night shift.
I have a short term storage plan for my 400 if I buy it as my space is limited.
Although there are two websites for this Honda I'm hoping quite a few sohc members might have knowledge of the 400N . Isn't the 400N a sohc engine?
-
Yes SOHC but 3 valves per cylinder.
-
Did lots of 250N at Meads and a couple of 400 so ask away mate
-
Thanks Bryan.
-
After gaining more information from the seller I've decided the 400N was an unfortunate combination of needing too much tlc and at a price that was reaaly too high in the current market plus too far away so viewing cancelled.
Back to square one. :( :( :(
-
Here's my advice Ted .. Join the Superdream forum (which I see you have done) and also the private Superdream Facebook Group .
I know lots of people on here are negative regarding Facebook but the closed private groups are great. I did this when I first got my CB250RS and got loads of valuable advice. I bet if you ask on the forum you joined and on the FB group, if you join, you will get good leads on suitable projects.
https://www.facebook.com/groups/1727379610678800
Seems you may be onto something with the Superdeam as DS posted this last year on Facebook.

I've joined both of the SD forums Ash. I've applied to join the FB group.
Made me wonder if Honda sold more SDs than 400/4s.
At the moment a couple I have found are just way too distant.
It will end up like Buses you don't see one for ages then three come at once.

Evidently in the UK 17000 Superdeam 250's sold in 1980 alone.
-
That reads as though they were a good seller.
-
The 250cc superdream was a current learner machine when I was a Star rider instructor, and a few ladies had problems with the seats being too high and they had to tip them to put a foot down, and they were not always successful, and the bike would tip over completely. Alot ended up with near side minor damage.
-
That sounds like it will be a good fit for my long legs. ;D

The trader (Charlie) here is top notch and never rips you off. Worth a call

Looks tidy! Early CB400NA model with the tidier small tail piece, (later ones were as CB900) and first gen Comstars. However no Kickstart - mine had one before they dropped it.
I actually liked the earlier Dream version looks but usually when you see them they are the awful automatic version.
Interesting to see what they will take for it.
-
I'm viewing a fairly local 400D Superdream next weekend that's within my budget so it will be interesting to see one up close and sit on one. Be interesting to know the price that Charlie is asking when he responds for comparison.
-
Ted the later models did not have that screwed plug at the front of the clutch cover if i remember correctly so you have to remove the clutch cover to adjust the balance chain idealy using new clutch cover gasket.
Not a difficult job as cover screws have 8mm heads not JIS just more to do on service, you also need to change the rocker cover rubber gasket and the seals under the holding down bolts, again not difficult just something to remember mate.
Whilst it is possible to convert a 250 to 400 it IS NOT just barrels and pistons so personally would not touch a converted one

When I bought my Bomber/CB72 etc they were selling a CB400A auto with 148 miles on it that had been left under a tarp outside (not left that long though). He wanted £2k but my mate Roger offered him £400 that he refused ... he later told us that it was sold for £500 but had been nicked from the lockup .. so he got nothing in the end. The person who stole it also stole the gear-lever off a CB250G5 I had bought and was stored with it... obviously didn't know it was an auto he was nicking !

I'm only looking at original CB400N models - I've seen a converted one - no thanks.
Handy tip about the clutch adjustment Bryan.

I always liked the looks of the black ones.

Think mine was Blue.
Honda missed a trick not doing a yellow option as we we know which 400/4 was the fastest.

A friend of mine had the purple one......I'm not sure that was a factory option!

Negatives for Yellow bikes.
1) Flies like to defecate on yellow surfaces.
2) Yellow paint fades quite quickly.
3) A bit of a Marmite colour choice.
Positives for Yellow bikes.
1) Sometimes cheaper used due to reason (3) above.
2) Good road safety visibilty.
3) They are generally faster.

. Jealousy
2) Yellow paint fades quite quickly.
That's down to the speed dragging paint off.
3) A bit of a Marmite colour choice.
Yep salty? That's what attracts the flies too

Limited market. Most people cant handle the speed differential against other colours.
2) Good road safety visibilty.
Need it.- be fast be seen!

Nope - always

I've been to look at a 400NA Superdream today and done a deal with the owner.
I'll post some photos when I take delivery, not sure if a project thread here fits the criteria for Steve.
-
Heh heh! Well done Ted! Good luck with that one.
-
The 500 was going to be my last project, at least this one should be more of a money puddle than a money pit - that's what I told Wendy anyway.
-
Well done and why not do a thread. Its a SOHC Honda.
Be good to follow something different.
Wasn't from Matlock was it?
-
Go for it Ted.

I will disclose the location after delivery.
I will pop it on a new project thread.

I am just hoping it's the one that Charlie at Oxford classics is selling .. cos it's a lovely example with tons of potential and wont give the buyer loads of heartache IMHO.

Great to read this Ted! Congratulations :-)

Think we need a round of 20 questions 😜

Thinking ahead Ted, if the balance chain is worn (and you'll probably replace it anyway) and if it's anything like the chain used used in the CB250RS, you will find it is an odd size. The original is very expensive (CMSNL had a CB250RS chain at something like £260+!!!). I sent my old chain to Andy Chain and he matched it up to a Go-Kart chain. He supplied a top spec gold DID chain cut and riveted to the correct length fir about £40.

Thanks for that advice Dave, that chain of yours was good value, the bike is a runner & rider having had the brake calipers sorted - there are bills from the owner for a substantial engine re-build by a firm that cost £1700 some 10k miles ago iirc plus invoices for a fortune spent by the PO in distant & recent years. It might change but at the moment I'm thinking the engine is okay hard to know until the exhuast blow on the balancer box is fixed - needs some cosmetic painting to the engine unit. Seat comes with a good base & new unfitted cover. Body work that is a non standard colour might clean up okay.
My thoughts are to dismantle most of it see if it really needs a frame paint, powder coat the fork ears that probably need re-chroming but I'm being sensible (today) with spending as they are not a high value bike when finished. The Comstar wheels are clean enough but a bit dull - might be worth looking at re-anodising type options or just call it Patina. Lots of bits that I will change like the braided brake lines - I like the standard look.
There is a variety of spare engine casings, parts that came from the last but one owner plus some new boxed parts purchased ready for fitting. He has another bike that needs some mainly cosmetic fettling a Yamaha 1300 that he wants to spend his limited time on as he works away all week. I would not hold him to his offer to give him first refusal to buy the bike back but it seemed a genuine request not BS. It needs at least one new tyre due to age.
-
Looking forward to a picture or two!
I had a CB900F for a couple of years. I love the 'Euro' styling but it was a big old bus and to heavy for me to push around the garage - although the moment it started riding it was fabulous and very light and well balanced. The Superdreams (preferably in silver!) have similar styling but far less bulky and less engine weight. I've always liked the look of them.
-
I am just hoping it's the one that Charlie at Oxford classics is selling .. cos it's a lovely example with tons of potential and wont give the buyer loads of heartache IMHO.
I had a provisional price/ ball park figure on that one - it was above my budget so I may repent at leisure.

Fair do's ... I suppose it was a little too good for a restoration project Ted. He always prices bikes reasonably though .. sometimes a bit low in fairness to him.
-
The good news Ash is it gives me an idea as to what a 400N Superdream might be worth so I will fix my budget accordingly. You are correct I'm in need of more homework, I am realistic enough to know it will be worth less than I spend on her, I'm unlikely to be able to ride or live long enough to get my money back. For me its all about the build with some red lines on cost.
For the first time I'm going to try to put a cap on my spending from the start, price up what needs doing before I spend any money for a planned 18-24 month project. The boxes of used parts might have some value to help with rebuild costs, or not.
There is a small oil leak at the front of the engine so the top of the engine at the very least will need to come off.
The one thing that is not going to suffer is the seat that has been replaced with a used one & comes with a complete new cover & strap ready for fitting. The base is said to be good so I will speak to some of the restorers that have been mentioned on here.
I have collected all the paperwork and a couple of boxes of used spares today so my first task will be to catalogue all the extra parts then identify them if it's not obvious. There is aso a small box of new parts in the deal. The bike itself is due to arrive sometime tommorow. I'll post some pictures up.

Looking forward to some pics of the new cash pit Ted!
