In part one of our Honda CL / CB350 carburetor rebuild series we show you step by step on how to disassemble the factory Keihin carbs found on Honda CL / CB350K series motorcycles. The tear down includes how to remove jets, emulsifier tubes, floats, mixture screw, slide and diaphragm. The carbs must be taken apart to this level so that the body and small parts can be properly cleaned and ready for rebuilding.

Thank you. Absolutely the place to seek parts from to support the channel.
THANK. YOU. Im doing my first ever carb overhaul on a 72 scrambler and you saved my ass, boss.
Loved the "expert" tip about shaking the float and listen for fuel, just in case the solder joint is leaking. Excellent!
Brendan you are the best. Clear concise videos with not a lot of extra talking or had gestures. Tells me just what I need to know and what to expect.
That diaphragm is in excellent condition. I've taken 10 apart and every one of them had 3 little tears over the air bleed brass inserts. A damaged diaphragm leads to "digital" throttle control where power snaps on and off. I am really amazed at the replacement parts you can get today that were not available to us in 1976, like diaphragms, floats (had to re-solder several of them), gasket kits, etc.
Removing carburetor assembly (CB250, CB360,CL360,CJ250T,CJ360T):
Remove left front foot peg. Remove gearshift pedal retaining screw. Remove gearshift pedal. Remove left rear crankcase cover (the cover where the clutch cable goes in--don't remove the clutch cable from the cover. The cover is held by four Phillips-head screws). Remove the hose clamps that hold the air-cleaner rubber intake ducts onto the choke sides of the carbs. Remove the air cleaners, still connected to their rubber ducts. Loosen the insulator ring clamps (The insulators are the rubber boots/ducts between cylinder heads and the carb intakes). Detach spark plug wires from plugs and put the wires out of the way. Be careful not to harm the ignition wire that goes into the points housing. Pry the carb assembly away from the head, toward where the air boxes were. Lower the carb assembly to the left and pull it out the left side. Detach the throttle cables from the carbs.
Enjoy the slow careful explanations and stopping to make sure the camera view is perfect. Thanks!
this guy is a lifesaver
Best how-to video's on youtube, massive thanks for taking the time to show us all how it's done. Respect.
This video helped me find out why my 70 CL350 was so unresponsive. Fluid in the bowls. Keep it up Common Motor!
I never get tired of the one!
Fantastic video!!! I love your step by step explanations. Just great and gets it done!
This is excellent information. Just got a 73 350 twin and need to re-jet the carbs after the exhaust modification. You've got a new member for your website!
You guys have helped me out so much, my 73 cl350 and 74 cb360 appreciate it!
Glad to help! Got to keep these old bike going!!!
Really excellent series of videos on the CB350 carbs. Very, very helpful. I'm sure I would have "unscrewed" and broken one of the emulsion tubes if not for you. (In fact, one that was in there was broken!) Thanks for the whole series!
simply excellent
Thank you for this video!
thank you, rebuilding dual carbs on my green cb350 bike thats been sitting for 20 years.
Very very helpful... Keep up the excellent job of informing us.. Thanks a lot.. stay safe..
Can’t wait till I get 450 Honda running
Your touching on many points that a good many people completely bypass or overlook entirely. The air bleeds and emulsion tubes seem to be oversights with quite a few folks I know. That plug for the transfer adjacent to air-fuel mixture screw the other. The last one bordering on the nightmare since many believe the carb is no good any longer as it can't be tuned without that plug.
great video, calm instruction on how to rebuild a cb350 carb. added bonus at 10:35 the magic finger moves the plug into frame.perfect. made me laugh.
Very detailed video, thanks! Can you tell me if this is the same carby for the CB250 1971? It looks identical. Ive removed the float bowl and everything looks the same as in your video.
Do you guys have choke butterflies replacement for the cb350 carbs or know where I can get some
I shaved down the chopstick with the Xacto for the smaller emulsifier tube removal.
That works great, most other woods break
nice!
great
Do you have a video on how to install the carbs in the bike?
That black rubber plug. Is it on the early carbs?
The shaft my butterfly rotates on is so stiff it feels solid. Any ideas on how to get it to move?
Great vid. You should edit it down just a bit, mostly when you’re screwing/unscreeing. Otherwise, Thankyou for the detailed information! I’m a noob with a 1974 CB 360
Can't find jet retaining clip on site. Need one over here.
Is this a similar process for the carbs on a cb350F?
Hi, did you have a video of how to get a pair of carburetors out of a 2-cylinder Honda motorcycle? Thanks
Good morning. I have a 70 SL350 with these carbs. I have them disassembled and I have your kits and diaphrams . I put them in an ultrasound cleaner and a lot of microscopic stuff came out. They look really clean to me. I don't really want to knock out all jets . Do you think it would be ok or not really.
Both my carb plungers/pistons are stuck in their bores. How do I get them loose?
My CB 350 runs great when warm but cold start choke don’t do anything and when I start it I can’t touch throttle or it stalls
does this hold true for a 73 CB350G?
I'm having issues with my K4. Someone suggested that I might have an air leak from the white plugs in my carbs. Have you come across this? My white plugs are both there, and don't seem loose.
Thanks
Its always possible. You can always seal and crack or a loose plug with epoxy. We also have a tech support line you can call and we can try to give you some troubleshooting tips and tricks.
My float bowls each a pin sized hole in the bottom by the brass insert, I'm guessing this isn't normal?
What did you soak them in since you didnt remove the shafts?
The carb bodies were washed in our parts washer with parts wash solvent.
My fuel inlet nipple came off the carb. How do I repair that??
I wondered why it was called Common motor- turns out it’s the street name where they are located
I cleaned my carbs, put them back on the engine and found the engine hard to start. When it started after about 6 kicks, the engine rev-ed to about 5k. The inlet butterflies were closed when this happens and when I press down hard on the throttle stop arms I can bring the revs down to tick over. Can you suggest what might be the cause? Does the butterfly have pivot seals that might be causing an air leak. When overhauling I noticed there wasn't a washer or seal in the air mixture screw, yet this wasn't a problem before cleaning.
Are your throttle cables installed and adjusted correctly?
@@wryanddry2266 the revving was happening when the throttle arms were seated which is the tick over position. Would it matter how the the cables were adjusted if the arms are seated. Cant remember for sure.
Pick tools ordered and Chinese food takeout ordered 👍
are these the same carbs on a 68-69 cb350?
Check our our carb ID guide video to tell the differences between the styles:

Thank you!! you guys are awesome!
You only deal with the twins?
No, we also support the CB550 4 cylinder
There's liquid in my float. Would that make the whole bike not start? Because the engine turns but won't start up.
It depends, I'd recommend contacting us over our support line at (510) 824-8575. We have it open Mondays or Tuesdays from 12-6pm. You can also shoot us an email through the website at common-motor.com and we can see if we can get some more information about what's going on with your 350 and get it running again for you.
Someone watching this is like, shit, how do I get the carbs off the bike? lol
I have a manual, just looking for quality parts at a fair price.
Well check out our store over at common-motor.com then. We work hard to test and evaluate every part we sell and we all use the same parts in our own personal vintage bikes.
But not the 350f
Have you checked online for a PDF manual for the 350F?
Interested but finding those weird gloves a bit off putting thanks anyway
