the tiny scews on top

[rusted]

There is a tiny screw on the top of each carb on the airbox side. What are they? And what are the screws in the sides that are covered with foil?
My bike is idling at about 5000 rpms. I have no idea why. I just cleaned the carbs the other day, and it was running fine. Then it started bogging down, so I limped back home. Now it only idles extremely high, and the idle screw does absolutely nothing. All the way in, all the way out, no difference.
Thanks for all your help, yall always help me get a different perspective that I cant see on my oun.

What type of bike and what year?

Could be the idle air screw if you have CV carbs. From the symptoms you discribe though the problem is not a simple adjustment.

When you say you cleaned the carbs what exactly did you do? GS bikes are very sensitive to air leaks and clean carbs. Unless you took the carbs competely apart and replaced all the o-rings, along with the carb boot O-rings (if your bike has them), you should consider doing so to assure everything is properly sealed/cleaned.

Check and see if the throttle linkage is hung up on something. Intake clamp screw maybe?

re

The bike is an 80 850G. The carbs were just rebuilt about a month ago. The bike has been ridden a couple of times since then with no problems, until the other day with sudden loss of power. I will check the tank screen in the morning. The linkage is not getting hung as far as I can tell. I'm startng to think its just possessed. the front end hasn't started spinning around though.

Do you mean that 5000 RPM is the slowest you can get the engine to run?
Or, that if you run it slower than that, it stumbles and dies?
