Slow speed jets....Your probably not getting any fuel to match the air flow for a slow idle....
When properly and accurately done,that bike can idle down to 400 rpm and sit there and idle fine...
Been there,done that.....Normal idle on my 78 was happy at 900 rpm.....it would even charge the battery there too.
The very best thing i did to the 78 was to replace the points with electronic ignition and the second was the electric fuel pump.....

The carbs can take many hours to service and attention to details is crucial....Ask if your not sure about what step 2 is....We have bunches of details on this bike... :)

After I "fixed" mine up right....I sold it....The test ride just scared me too much :o
Just something about the front wheel wanting to lift off the road.....My grin turned into a panic in 2nd gear......

One other thought could be a cracked vacuum line. There are quite a few and some are hard to see. But at that age they are becoming brittle and would cause the same symptoms.

Vacuum leaks are the first I would look at, as they are easy to fix. The 1977 had a very lean low speed circuit, so if the fuel gets restricted just a touch it may not idle at all from the low speed circuit. So try doing the low speed air jet modification and see if that helps.

dbenson, you let us know your problem but no the history. Any chance your bike sat for several months or more without MMO or Stabil Marine in the tank? These carbs are awesome if you ride, not great at sitting however. Honda expected us to ride. When the bike sits, the fuel of today can break down and leave you will carburetor port blockage. It is also possible that you have one or more stuck sliders in your 4 carbs. The sliders go up at high rpm to let in more air, but that makes it too lean at low speed so they close. If they hang up, the one or more offending sliders will kill that cylinder at lower speed. So I would look at the sliders first, but perhaps consider a carb rebuild if the bike has been sitting for a year or more already without regular use.

I am sorry I do not know the bikes history, it ran when I bought it and I just needed it to put around town to work. Since then it has grown on me and now I am attached to it and would like it to run proper.

You may be best to get Randakks Video and rebuild the carbs.

Check the 4 o-rings where the ports attach to the head first. It's easier and they have a tendancy to break.
