    Help with carbs on 81 CB750C

    Oops my bad. Sorry
  2. NicksHonda

    1981 CB750C running on 3 cylinders.

    I have had the air cut off valve leak and the cylinder runs way rich at idle up to about 4k rpms. It runs so rich the plug can't fire at idle. My symptoms showed if I could get it above 4K rpms suddenly the bike took off and ran great! But it struggled around idle and up to about 4k rpms. I...

    Help with CB750C turn signals

    oh ok. I wonder if some of the wires got connected incorrectly inside the headlight bucket. Or a bad ground or bad switch still.

    Help with CB750C turn signals

    I am not sure what you mean in your last sentence. When you turn on your left turn signals on, the right and brake light turns off??? Sounds like it might be a bad ground or a bad connection in the switch. Was it working before the LED change? Good luck

    Installing DCC speedometer on CB750

    IIRC - the oil light and the brake light are the same on the dash. Are you sure the rear brake light is working? Or if you did as I did and replace the rear brake light with an LED, the "oil/brake" light comes on in the dash. Good luck.

    81 750C misfiring under acceleration

    I'd check around your wires for arcing. Probably need to do it at night. I forget there used to be a trick with simple-green or armor all or some other cleaner that "helped" show arcing. Perhaps if you just move the wires around so they don't get close to each other will help. Good luck.

    Help with carbs on 81 CB750C

    Usually you would need to go up about 10 or so in size. It's mostly trial and error tho. Good luck.

    LED lights on 81 CB750C

    As I recall, I simply replaced my relay with the LED relay and put in LED bulbs in the factory outlets. Do you have something different?

    Hesitation when bliping the throttle

    That's interesting... my #2 plug was wet with fuel. I plugged the ACV (side port) and now it runs well. I assumed it was running too rich to fire the #2. Maybe it was the accelerator pump. IDK.

    oil/gas mix on the starter cover

    I am not sure where to post this in the forums since I am not sure it is a carb leak. I seem to get oil under the carb#2 and all over my starter cover. I can only think this is an oil-breather tube leak. But it smells like gas. The liquid feels like oil. I only get this after it runs...

    Oil or gas on starter cover

    I am finding an oil/gas mix on top of my starter cover. Could the oil breather tubes leak around the carbs? The breather hoses all check out OK. I have clips on the hoses and T-connections. It seems very weird. Seems like I have two issues, an oil breather tube leak and a carb leak. I...
