I own this bike...this is me riding it. I say you need to adjust your points!! ..better yet get a new set of point installed and have them set properly with the correct timing adjustment. I bought this bike, cleaned the carbs and was only able to get about 90 mph after a long strait. Then I adjusted the point and easy got an extra 10mph top speed!! Do your cam chain adjustment!!! It's super easy to do and can save you plenty of frustration in the long run.
The CB400 Custom was a twin. You will never be able to achieve this sound with a twin. :D My suggestion is to leave that engine in stock trim as you will most likely achieve the best performance all around!!
I had 4 of these bikes and rode the arse off them and it would cruise happily at 90 which I did a lot in the 70, on our motorways in the GB, the only down side was the can chain tensioner and the head gasket
yep in mean time of my last Q ive had the carbs open and cleaned it out resetting the float level and tinkeing with air bleed , it helped a lot on perfomance . through out the summer ive rode it with pleasure and still need to go on a ajstment spree with it ,but its way more economical and faster then it was before, ive had it reaching 100mph and in city riding its fun as h*ll. when getting warm its still suffering a bit of fuell rich mix tho.
well now congrats on the bike its neat (to say the least) and thanx for the answer, ive got it for free and with all new electronics(almost original) and ive just found out yeasterday it was my valves that wasent ajustet properly i usually work in metric system but my blades where in inches!!??donno how i got them but,,,went on the highway today and at 130kmph it was stil reactin on thottle responce( positivly)so hope weather turns to the better soon so i can have a try at it.
Allan, I was replying to a comment posted asking what exhaust system this is and that they wanted to install something like it on their 400custom. The Honda 400 Custom was made in the 1980's and was a TWIN CYLINDER. Read back and you will find it.
wats done to it other then ignition and whats written,eny engine rebore or just well kept?mines gone way past 150,000 km or near 100,000 miles and only just got its top end redone.your friends sounds awsome...
with careful maintinance and tuning you will reach the ton 100mph - 160kph , I have had mine do 172kph ant still had more on tap to go, I was using 98 octane fuel as well, I had not long reconditioned the carbs
that is no twin mate it is a 1975 400F super sport, he is more than likely calling it a custom due to the exhaust system and other mods he may have done, I have 2 of these bikes and they are great fun and as reliable as clockwork
Good ear! If you listen carefully, he made the 1-2 shift but it fell out of second gear about half a second after the gear change. Ehh, old gearboxes are allowed to have at least one quirk! 🏁🏁
Used to race one of these back in the 70's

Hey man. What exhaust is on her? Ill be acquiring a 400custom soon an im looking for exhaust with this sound.
4 in to 1 exhaust - ie 4 cylinders in and one tail pipe / muffler out
I had one just like it that thing is bad to the bone
whats its top speed ? sounds like rewing all the way out in top gear! mine is a 77 and my top speed is 130 kmph or about 81 mph kinda sad and slow

I heard that. At 1:22, you missed a gear. tsk tsk tsk😝

Hey, I am keeping my original exhaust system preserved for a later date....besides they are way to quiet for my taste. ...so shame on me...shame. :P
Shame on you for removing the original exhaust! Always reminded me of headers on one side of a V8.
what a noise
check my one out its lovely looking cb400/4 1975.would not ride my one like that.your video is amazing.but i think you need a ZX10
