Why does my bike idle weird?
Carbon, oil residue and pitting on the spark plug electrodes will cause a weak or inconsistent spark, resulting in poor ignition and an inconsistent idle. A clogged air filter may not allow a sufficient amount of air into the combustion chamber, contributing to a rough idle.
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.
Which is the best idle speed for a bike?
While the bike is warming up the RPM can be a little higher than at operating temperature. The best idle speed really depends on the type of engine and air to fuel ratio. The best thing you can do to figure out what idle speed is best for your bike, is to search in the user manual.
What’s the difference between high idle and low idle?
Step by step automotive repair guide on how to troubleshoot and fix an engine that is idling high (fast) or low (slow). (Note: The engine idle speed is controlled by the computer and is NOT adjustable.)
Why does my motorcycle idle at too high RPM?
Louder than usual noise from the motor winding up to higher RPM. You may hear a loud grind sound when you put the bike into gear because the RPM are too high even when you are off the throttle. Here are some of the probable causes of your high RPM. Idle Screw isn’t set properly or the ECU isn’t setup correctly.
What does it mean when your bike won’t idle?
1. Engine starts with medium choke and slight throttle 2. Must hold slight throttle and feather choke to keep engine running 3. Engine will rev with throttle, but is rough at times (because it is choked) 4. If I release throttle then the engine dies immediately 5. If I turn choke completely off then the engine gets weaker and weaker until it dies
What happens when the Idle is high on a Harley Davidson?
Strange that there are no historical codes since you did say you saw the check engine light come on. (Could be you went through 50 key cycles with no engine issues) When you get off the interstate & the idle is high,,, if you were to power it off and restart the bike, does the idle calm down or does it resume the high idle.

Where is the idle button on a motorcycle?
The screw is usually located on the carburetor near the choke. This same screw system is used on the first generation of fuel injected motorcycle engines. Newer models that have fuel injection systems have an ECU (Engine Control Unit) that controls the idle level. If your bike has an ECU you cannot adjust the idle easily.
