Then, adjust the idle speed back to 1500 rpm.
This procedure will work for most other bikes but on the DR650 setting the mixture screw this way will often result in a slight "rich bog" just off idle. If you aren't going to make other changes to avoid the rich bog most riders have good results turning the mixture screw about 1/4 turn leaner than the highest idle.
