I need some help. I've been struggling with this problem for about a month. I have read various posts and articles continue to suffer from a high idle when my bike is cold. I bought this bike and it didn't run. It's a 1979 Honda CB750F (or so I was told). When I bought the bike there was a hole in the block so I decided to rebuild the engine since it was going to be mostly disassembled anyway. After doing that it didn't make much sense to not do a carb rebuild as well. I did a bench sync on the carbs and installed them. I tried firing up the bike and it ran like sh*t, but it ran. The mixture seems very lean because I noticed the idle climbed to 5k. I turned the pilot screws out to 2 full turns. I tried cleaning the pilot Jets three times and still I'm having this issue. My carbs are the 79 model so it has the pressed in pilot (whatever the f*ck you call them).
As you can tell, I'm a bit frustrated at this point as I have run out of ideas. Please have a look at the link to my video for a sample.
Any help is greatly appreciated!
