    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.

    Loved the "expert" tip about shaking the float and listen for fuel, just in case the solder joint is leaking. Excellent!

  • @tsbrownie

    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.

    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!

    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.

    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.

    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.

  • @brianobrien
    @brianobrien Před 8 měsíci

    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.

      @@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.

      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.
