When does idle come back to normal on a Harley Davidson?
Just seems to happen when I’ve been running at a fairly wide open throttle maintaining higher speeds for a while (fwy) or longer stints (catching all green lights) on the streets at a speed of about 45 or more. It always seems to come back to a normal idle after getting back into first gear when stopped, or when I start going again in 1st.

How is the idle level on a motorcycle set?

How to troubleshoot a rough idle in a car?
Bad compression indicates worn rings, pistons and cylinders; the engine requires a rebuild to rectify this condition. Inspect the fuel in the tank for signs of water, dirt or rust flakes in the fuel tank. Clean the tank and re-coat as necessary. Remove and inspect the fuel filter.
What should I do if my motorcycle is sputtering?
Start by checking the easiest spot first which would be the spark plugs. Take out your spark plugs and make sure there is no nasty build up on them or any type of corrosion. Also make sure the point isn’t worn down and that the gap between the center and the ground electrode is the appropriate distance.
What causes a carburetor on a motorcycle to sputter?
Vacuum port plugs are cheap and are easy to install. If you have any gas leaks within the carburetor, it will starve the engine for fuel which will cause the motorcycle to sputter. Leaks within a carburetor is usually caused by a brittle or cracked gasket that is just above the float bowl at the bottom of the carburetor.
Why does my Honda have a high idle?
If that’s the case, it creates a large vacuum leak. When this happens, it effects the idle as well as fuel economy. Usually if the PCV valve fails in this manner, you’ll experience a ‘high’ or ‘hunting’ idle.
How to troubleshoot a rough idle in a motorcycle?
Check the carburetor idle circuit for blockage. Check the fuel injectors for damage or blockage if applicable. Ensure the carburetors are synchronized if the motorcycle uses multiple carburetors. Make certain the battery is fully charged and all battery cables are tight and free of corrosion and sulfate deposits.
What does it mean when your motorcycle engine is sputtering?
Vacuum leaks can cause several problems with the functionality of a motorcycle, especially sputtering. If there’s a vacuum leak, that means the carburetor isn’t giving the proper amount of air to the air and fuel mixture which will ultimately result in sputtering and poor engine performance.
What should I do if my bike is sputtering?
While ensuring you are wearing safety glasses, apply carb cleaner vigorously through the holes of the jets and through the entire carburetor. You should then use compressed air to blow any gunk or debris that could be stuck in the jets or the bottom bowl inside the carburetor.

In addition to a sticking cable or throttle mechanism, that is sometimes caused by leaving the “choke” on too long or by an air leak around the carbs……assuming that it HAS carbs. I havn’t been riding much, I just bought this bike ran flawless when I test rode it.
