To bring the idle down on a Yamaha badger is really easy. All you have to do is adjust the fuel settings on the carburetor.
By turning the idle adjustment screw located near the choke lever under the carburetor. Counter-clockwise lowers it, clockwise raises it.
To set the idle, adjust the carburetor.
The Yamaha Raider does not have a idle adjustment based on the fact it has no carbs. It is fuel injected and auto adjusts based on the temperature and fuel delivery.
there is a little screw on the back of the carb. if you loosen it, it will idle slower, tighten it, it will idle faster.
On the side of the carb.

The idle speed on a 1987 Chevy Celebrity is controlled by the engine computer, there is no way provided to adjust it.
