Carb Cleaning Question

Postby Fulcrum » Fri Mar 15, 2013 5:51 pm



I'm removing and cleaning out the carbs on my 82 1100 and want to know if it is necessary or of any benefit to separate the two carbs from each other on each side. Meaning separating the #1 and #3 carbs from each other and the same for the #2 and #4 or if I can just leave them as a set and clean them out. Thanks

I'm trying to remember.I don't think I removed the carbs from the Plenum other than to remove and service the air cutoff valve.One of mine had to have all 4 valves replaced.It was needed to clean the ports and check that the valve moved smooth.2 of them were corroded in.

Yes, that's the biggest reason for seperating the carbs from each other; otherwise it's virtually impossible to get to the air cutoff valves.
If also permits a more thorough cleaning, as you'll have access to the cross-over tubes and plenum passages, and be able to replace their associated seals.

One very important tip. As you remove each carb take a picture of the mating surface where it bolts to the plenum. There are O-rings in there and you want to make sure that you put them back where they came from. It's very easy to overlook one or two and the result will be fuel pouring out of the plenum.

Now you tell me! lol Actually I didn't take a pic of that cause my camera card is full and I can't find the usb cable for the computer. I have hundreds of pics on it. I did find one O ring when I was washing the plenum and I'm not sure yet where it goes. So, Very good advice!

Check Roady's thread at NGW for O ring locations:

As I recall, big ones are fuel transfer for the float bowls, small ones are the accel pump passages.
