Is it normal for a bike to increase its idle speed?
It is normal for curb idle to increase several hundred RPMs as full operating temperature is achieved. Caution: a “good” idle speed when half warmed up will be too high when fully warmed up, so you must accept the inevitable requirement for some “throttle nursing” until the bike is fully warm.
How long does it take to get a bike back to idle?
Improper setting of the curb idle speed. This should be done with an accurate shop-grade tach since the tachs on these bikes are notoriously inaccurate! Curb idle should be checked and re-set on a fully warmed engine. “Fully warmed” takes 15-20 minutes of running in typical weather.
Why does the idle go down when the engine is warm?
Started it and found out that when engine gets warm the idle will be stuck at 3-4K revs, it only will go down when letting the clutch come on. -chg the carb holders all 4, were in bad condition. -checked the choke and throttle cable, run without having it attached.
What causes a motorcycle to stall at idle?
Extremely lean motors can also stall out completely when given some light throttle. Another sign of lean running is the “hunting idle” where the motorcycle revs up randomly, changes RPMs, or takes forever to come down to idle.

Why does my car run so slow at idle?
A related and common cause is blocked idle circuits. Again, one or more cylinders have to compensate for the one (s) not contributing at idle. You then have to screw the curb idle screw into the point that the progression circuits are activated. Havoc ensues.
Why does my car take so long to return to idle?
Poor carb sync is the most common reason for your complaint. The reason for this is that when the carbs aren’t synched well, one or more cylinders have to compensate for the underperforming ones (at idle). This gets the harder working cylinders into the progression of fuel circuits (at idle) to maintain proper curb idle.
Can a GL1000 do a lazy return to idle?
The idle circuits in a GL1000 are ridiculously small, so slight problems are greatly magnified. To summarize, the solutions for a lazy / slow return to idle (or erratically high idle) are: Perfect idle circuits – usually requires a thorough carb overhaul, but this is worth trying this in situ carb cleaning method first.
What causes a car to have a high idle speed?
It only takes a small extra amount of fuel in a low/no-load situation to cause an unnaturally high idle. To make matters worse, this usually activates the centrifugal ignition advancer and you get wild oscillations in idle speed. However, it’s not well understood that the synch mechanisms incorporate spring-loaded connections in numerous spots.
What should the idle speed be on a Honda Civic?
Turn off the car. Reconnect the IACV, and reset the ECU by unplugging the back-up fuse. Restart the engine, and the idle speed should be in the 620 to 720 rpm range. Replacing the entire throttle body is probably the best option if this is the case, but that’s an expensive fix.
What causes the engine rpm to go up when idle?
When the engine idles, there will usually be a misfire that you can feel just from holding onto the steering wheel. Furthermore, the RPM of your engine will be higher than normal when the vehicle is idling. The RPM will usually go back to normal as you accelerate the vehicle, but will increase again after you stop.
What happens to your car when you idle it?
When the engine idles, there will usually be a misfire that you can feel just from holding onto the steering wheel. Furthermore, the RPM of your engine will be higher than normal when the vehicle is idle. The RPM will usually go back to normal as you accelerate the vehicle, but will increase again after you stop.
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.
