Gently push the linkage rearward to take the pressure off and turn the idle screw counter clockwise (up) to increase idle speed, turn the idle screw clockwise (down) to decrease idle speed. There is risk for running the motorcycle idle too low. Routine idle speed adjustment during maintenance services is not necessary nor desired. The flickering oil indicator light in your speedometer is a clear sign of something being wrong with your car. To offset the poor combustion, higher fluid viscosities, and undesirable emissions at cold start, idle speed should be increased at low engine temperatures. Fixing must be avoided. If idle is stable at 800 rpm and 190 degrees F, this idle speed is usually fine down to about 160 degrees F. Expect to add up to 400 rpm at freezing to allow for smooth engine operation, with a smooth transition as temperature changes. A blip of the throttle sometimes coaxes it up. The best idle speed really depends on the type of engine and air to fuel ratio. Pay attention to low idle or stalling. Our firm recommandation is to keep the idle at the factory level, and if you must change it, you should aim for slightly higher idle level. Here are some things you might want to check, to see if all is well with your precious car. If the idle speed is too low, the engine will stall.

Engine stalling issue at low speeds. If your carb has three screws to tweak, you'll see labels. The best thing you can do to figure out what idle speed is best for your bike, is to search in the user manual. The goal is to allow the engine to idle at as low an RPM as possible yet keep the engine from running rough and stalling when power-consuming accessories, such as air-conditioning compressors and alternators, turn on. The low idle speed adjustment switch enables the driver to adjust the low idle speed using a two-position momentary toggle switch. Low idle and fluctuating idle symptoms and trouble codes.
