Why is my motorcycle idle speed too low or too high?
If you aren’t going to set your idle to the factory level then you should always aim for high idle speed over lower. If your bike has been warmed up and is idling lower than the recommended level from the manufacturer, you probably have a couple of problems: The engine will stall easily or may not stay running without throttle being added.
What should the idle RPM be on a car?
Your engine should normally get to around 700 RPM after you start the vehicle, depending on the model. If your idle is way off and you have one or more of the problems listed above, then you will want to diagnose the issue right away.
Is it normal to have a rough idle?
This is definitely not a normal situation. If you are experiencing a rough idle or your RPM is running high, then there are a variety of reasons for why this could be happening. It is not always easy to diagnose the cause because there are so many factors involved here. Below are the top 5 causes that a mechanic would look for.
How do you set the idle on a motorcycle?
Many older motorcycles that use a carburetor to mix the air and fuel, set the idle with a simple stop screw. The screw prevents the throttle valves from closing completely, allowing fuel to consistently flow into the motor when you are off of the throttle. Just simply turn the screw in or out to adjust the idle.

What happens if the idle level is too low?
Idle level too low. If the idle level on your (warmed up) engine is lower than the level decided by the manufactorer, you will usually have two problems: – The oil pressure inside the engine will be very low, and you may see the oil pressure lamp flicker. – Charcoal cannister in the tank ventilation line clogged by fuel or dirt.
How is the idle level of a motorcycle controlled?
The same system is used on the first generations of fuel injected motorcycle engines. On the newer fuel injection systems, the throttle valve is controlled but a small stepper engine, and it is the fuel injection ECU (a computer) that is controlling the idle level.
What causes low oil pressure on a motorcycle?
The low oil pressure issue at a very low idle level is a genuine risk. The rest of the text below contains lists of the possible causes if the idle level on your bike is too low or too high. Please note that we are focusing on fuel injected motorcycles here, so the list of root causes does not necessarily apply to the older carburettor bikes.
What should the idle speed be on a motorcycle?
And you will usually not be able to adjust the idle level in any way. Usually we see the idle speed being between 1000 and 1300 RPM (engine revolutions per minute) when the engine is at operating temperature, and often as bit higher during warm up.
