Hi, I'm Faska,

Thanks for a very nice video! I did this job on my CB400N today, and your video was really helpful. And thank you SO much for NOT adding any annoying music! 🙂

[@FaskaRestoration]

Glad I could help :D

[@normanwhite3104]

Fantastic video, really shows how easy its change the oil on your superdream, this is showing the 400N and its the same application for the 250N superdream ❤

[@prout27cat]

Thanks mate you saved me… I had a persistent leak from near the filter housing…thanks to your clear video the problem became apparent, the previous owner had put the spring on the outside of the central nut😲😅

[@FaskaRestoration]

Im glad I could help. 😃

[@mickhenson1]

Hi Faska, great video I've just started up my CB400 after 15 years. changing the oil is my next job

[@FaskaRestoration]

That's awesome! I hope my video is helping you.

[@alfiedodah9799]

Use a six point socket, replace the missing shim washer at the oil filter spring, torque setting oil filter bolt 20-23 ft/lbs, replace crush washer sump plug, torque setting 25 ft/lb.....do it right

[@roum22]

Well said Alfie...You saved me the bother..

[@piperjomo]

There should be a washer between the spring and filter

[@FaskaRestoration]

What really? Do you have a picture or a part number? Thx for the info.

[@piperjomo]

Its part no 5 (only a thin washer) This link is for a 250 but 400 is the same. www.cmsnl.com/honda-cb250n-1978-england_model15802/partslist/E12.html#.YLonGuHPyyI

[@piperjomo]

When you take off the filter the washer is stuck to it and usually thrown away with the filter.

[@chuckbuckley6425]

Are you going to do a strip down on this one too? Just bought the same bike, so would love to see it done before I get into it haha. Just getting it running first haha. Your other videos are great. Keep it up.

[@FaskaRestoration]

No she is in perfect condition. Only the front bakes don't work. I hope you have fun with your Honda, and get it running Oh and my clutch is slipping. Thank you very much :D.

[@statendrei5]

How can i tell between the honda cb400n 27hp and 43 hp model?

[@FaskaRestoration]

Either you can feel it that she has more power, or you look in the papers it should stand there. The engine is basicly the same just the camshaft is sharper, if you find a 43hp camshaft you can easily convert it. I hope this has helped you.

[@Beppis9]

Hi Faska, which types is your CB mounting? great vid btw, eager to watch more

[@FaskaRestoration]

Sorry can you explain a little bit what you mean? Thank you. There will be a few more videos about the Honda but not in the near future. (Brakes/brake lines...)

[@Beppis9]

Faska Restoration sorry i meant tyres:)

[@joakimeliasson3244]

Hi! Although not drilled from factory, your engine seems to have the features for attaching an oil cooler on the engine case. As I've seen that older models doesn't have this I'm therefore curious what year your bike is? If you also happened to know what engine model you have that would be really nice to know.

[@FaskaRestoration]

What, where? I didn't even know that there existed oil cooling for this model. My model was first registered in (European date) 5.4.1982. Everything is still original. And if you tell me where I can find the engine code/Modell I'll write it too.

[@joakimeliasson3244]

​@@FaskaRestoration From what I can tell so far only the cb450 n/dx/sc and possibly other versions made for the brazil market came with oil coolers. The coolers were connected through holes in the lower crankcase just above the filter. I've highlighted this here drive.google.com/file/d/1uELkBzlixsv3zJeideEerDqma6UERcVF/view?usp=sharing Oil coolers came in two variants, mounted higher on the frame or directly on the motor. Most models I've seen of the cb400 have regular fins all across the lower crankcase. Since the cb 450 sc came out in 82 with just slightly larger bore it would make sense for honda to share the same engine castings for both models. I'm not actually sure there would be any indication on the crankcase to tell the difference but I would think all of the same version (A/B/C/D) version would have the same crankcase. Since your bike is 82 that would be either a late B version or early C from what I know. Most likely C since the B versions are probably too early for having that crankcase. I believe if you check your VIN it would be CB400N23XXXX if it's a C model or cb400N22XXXXX if it's a B model.

[@FaskaRestoration]

@@joakimeliasson3244 Wow you know a lot about Honda I've checked It and it's actually CB400N32XXXXX... What does that mean? Oh and I found out that it was build 28.1.1982, but it was sold and got a license plate 5.4.1982 (European date). And I have another question it's a cb400n like you can see and read all over the bike, but in the paper the model is " CB 400 T" how or what? Maybe a mistake?

[@joakimeliasson3244]

@@FaskaRestoration Wow that's really interesting. I've heard many mistakes were made registering bikes back in the day so it is possible. Since the F and T stood for four and twin respectively in the precursors cb400T and cb400F and the sibling bike to the CB400N were named CM400T (T=Touring), they might have put a T instead of a N seeing as it could be confusing. Some countrys including Germany imported restricted models as well as standard models. Restricted models came with different VIN, in the case of Germany they would usually add 1 to the first digit, thus your bike would be equivalent to cb400n22xxxxx, ie. model B but restricted to 20kW. Maybe you could see in the papers if it's still restricted or if it ever was restricted?

[@FaskaRestoration]

@@joakimeliasson3244 Very interesting. It's actually still restricted to 27ps/20kw they did that because of the insurance. In Germany if your bike was under 27/20kw ps it was a lot cheaper to insure. This was done through a different camshaft, but it is exactly the same engine. We still have something like that in Germany but the rules (different ps/kw and weight) had changed a lot and today you have 3 different types of motorcycle driver licenses too. (Too complicatet to write it all down here)

[@giovannibarbieri4410]

Buongiorno Dove l'hai comprato il filtro e le varie guarnizioni??? Ed a che costo?????

[@FaskaRestoration]

At a Honda dealership, I think 20€

[@calebrobb4292]

What is the other o ring for?? The bigger round one in the packet?

[@FaskaRestoration]

It's also for the Oilfilter housing.

[@stanisaww9543]

Hi do you have a oil lick in cower oil filter and carter ? I have a Honda cb400 N 1982 and I have a oil leak on connection betwen engine part and cower oil filter , I have change cover , and new gasket . 2 months later leak is again , I see you have a oil marks on muffler , it's normal in thease moto ? Please coment

[@FaskaRestoration]

No I have no Leake in the cower, the oil marks on my muffler are 100% my fault I spilled some off camera. Did you use new o ring as well? Or maybe it is the hollow screw that has a crack somewhere?

[@FaskaRestoration]

@@stanisaww9543 could it be possible that your oil pan has a small Crack?

[@gamlebardun]

Ive heard youre supposed to oil up the o ring before mounting💁‍♂️

[@FaskaRestoration]

@@gamlebardun Yes that is correct 3:38

[@garydunn3037]

Its not exactly "Rocket Science" I did this every 1000 miles on my 250N SuperDream and noticed immediately how much smoother the engine and gear shifts were after.

[@garydunn3037]

By the way, I never changed the rubber gaskets and had no leaks, all was fine.

[@joeyengelkes9370]

When is Comming a New zundapp video out?

[@FaskaRestoration]

It is nearly finished. There are still a few things to do.

[@bikedogtor1663]

Hab ich auch noch nie gesehen wie der ölfilter eingebaut ist. Komische Lösung.

[@FaskaRestoration]

Finde ich auch, vorallem das der Filter mit einer Feder nach oben gedrückt wird.

[@fredfraggle683]

Seltsam, ja. Mit wie viel Drehmoment hast du denn die Ölablassschraube und die Schraube des Ölfiltergehäuses angezogen?

[@FaskaRestoration]

@@fredfraggle683 Das habe ich nach Gefühl gemacht. So fest das es nicht abfällt aber auch nicht festknallen das es abreißt. Wenn du merkst das es undicht ist kannst du ja noch ein bisschen nachziehen.

[@normanwhite3104]

Ditto 😂
