- Most Hondas from the early 80s used these style of Keihin Carburetors. This is from a CB400N, very compatable with CB250N. The logic of parts will work for other Hondas of this era also.
Ultrasonic Cleaning etc done. As i did a straight through exhaust after a total engine rebuild I ended up jetting it stock pilot with 2.5 turns out on fuel screw, 92 secondary and 113 main. up from 78/108 stock. TOTAL RIPPA OF A BIKE.

Pm me for a guide if link doesn’t work
nice explanation of things as you move through the rebuild. Thanks
Looks like a nice clean carb. Always good to give them a once over
Great rebuild skills 💪💪💪
Nice bro
Same carbs on the CM400T, good video, good song.
Hahah thanks mate! My first one. Should I do more?
Nice video Sir, I have some doubts about that carburator, where can I contact you?
Great Video, I have CB400N which i am turning into cafe racer, with straight through pipes and cone filters instead of airbox, what do i need to upgrade on my carbs, any advise would be greatly appreciated.
Hi mate. You will need bigger jets for pilot and for main. I don’t know if I reference mine but say stock is 26 pilot and 145 main you will want 30 pilot and 155 main. Go up 4-6 sizes in oikor and 10 or so on main. If you can keep stock airbox please do the bikes run so much better if you can’t please buy slide carbs from mikuni Oz, they will sell carbs and jet kit for your bike. If you must keep stock carbs and need pod filters get UNI pod filters the foam ones. The pleated ones are shit for vacuum but if your heart wants pleated ones buy K&N or DNA (easier to get to AU DNA). High quality. Stock airbox for the win unless you buy new slide carbs cause it won’t draw vacuum properly. It’s been done. But it’s never easy or fun
@@revivemotorcycles will i get away with 92 secondary 113 Main and UNI Foam pods on stock carbs? sorry, bit of a newby on cards ( i have ordered the book you mentioned :-))
Is this similar to the cb 400t carbs?
Do you by any chance know where I could get the throttle flaps ? Or what other models use the same ones? Recently bought one and the guy that took it apart unfortunately lost some of the parts so I’m trying to piece back together.
I have a set of carbs for the 250 not sure If diameter is same probably not can you measure your intake ID
Ebay
In my new rebuild kit needles are longer than originals - can I use ithem? Thx!
How much longer? Depends on the taper but prob not
If it’s Less than 1mm go for it. What kind of rebuild kit is it? The brand? I’ve noticed you can’t shim these needles either
A motorcycle "mechanic" doesn't know how to pronounce "Keihin" (Keehin). Sheesh....
Never to ashamed to learn! So it’s Keehin? Like Keenan but with a H?
