Can you lower the idle speed?
Loosen the screw in a counter-clockwise fashion to increase idle speed or tighten it in a clockwise manner in order to decrease the idle speed. Ideally, you will want the idle to rest at 650 RPM.
Why is my idle so high?
Here are some of the most common reasons for an engine to be idling high. The most common problem is a faulty fuse. In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. When your car’s throttle is malfunctioning, this can cause your car to stall or idle high.
Is it bad to let a motorcycle idle?
Letting a motorcycle idle is not bad provided that it is not done excessively. Liquid cooled motorcycles can tolerate idling better compared to air cooled motorcycles and temperature should be considered when it comes to letting an air cooled engine idle.
What RPM should a Harley idle at?
approximately 950-1050 RPM
To ensure proper charging at idle, maintain an idle speed of approximately 950-1050 RPM. Insufficient idle speed may drain the battery in excessive idle situations, resulting in insufficient voltage to the ECM, ignition coil and fuel pump (which can result in a variety of operating problems).
What do you use to adjust idle speed?
What I’m trying to adjust the idle with is the curb idle adjusting screw: The Holley tuning video says “the curb idle adjusting screw sets the idle speed by opening and closing the primary throttle plate”. I did not adjust any screws that are internal to the carb, and in fact have not had the carb removed.
How to adjust idle speed on a V-twin?
U can adjust the M&M idle with the aforementioned Torx set screw. Find the torx screw. With the engine hot, weather warm, back the screw off a “noted” amount… 1/16,1/8 ect. Put it back all together and ride it for a time to see what effect the change made under all conditions {starting hot, cold, riding in traffic, exhaust note ect.}
What to do when idle is not coming down?
We’re not fast racers, we’re more what’s known as half fast racers. If you have no vacuum leaks, It sounds like your secondaries are open. Then turn the secondary stop out until the idle starts to come down to the desired level. Then fine tune the idle with the primary. You may need to reset the idle mixture screws and repeat the process.
Can you get your idle speed below 1400?
I can’t get my idle speed below 1400! I don’t mean that the car won’t keep running with the idle set lower, what I mean is even with the idle speed adjustment screw backed all the way out till it’s not even touching the linkage the idle doesn’t go any slower. The car is running fine other than that problem.
