Idle
The base idle can be changed by turning the brass colored screw on the throttle body. The screen is in the injector. Remove the tank, remove the fuel line to the injector. Look in the inlet port of the injector and clean that screen, if needed change the line. Hope this helps.

You can bump up the idle but I've found the fuel lines deteriorate and the screen in the injector needs to be cleaned as well.
Just as a preventative measure, and no cost.
