Honda CB400N Carburetor Rebuild and Clean Instruction Video
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.

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 :-))
Nice video Sir, I have some doubts about that carburator, where can I contact you?
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.

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....
