Why is my motorcycle revving on its own?

Why is my motorcycle revving on its own?

A motorcycle idles high when it is getting too much of an air and fuel mixture in a low speed or neutral position. This is usually caused by the idle screw on the carburetor being out of adjustment, an out of place throttle handle screw, a bad carburetor throttle spring, or a sticky throttle or throttle cable.

Why does my motorcycle Rev without the throttle?

When the throttle is applied it seems like it revs sometimes but not how a normal motorcycle would. The first thing I would do is check for proper operation of the throttle cables. Make sure they are returning to the proper location and not holding the throttle open by being gunned up or in a bind somewhere along their routing.

What should the idle speed be if the throttle is turned off?

If the ignition is turned off with the throttle in a position other than 0 percent throttle, the system wants to use a higher rpm as the new idle speed the next time the engine is started. If you shut the bike off at 1,800 rpm, the next time you start the engine it will use approximately 1,400 as the new idle speed.

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.

What does the reset function do on a Harley Davidson?

Built into the system is a reset function. If the ignition is turned off with the throttle in a position other than 0 percent throttle, the system wants to use a higher rpm as the new idle speed the next time the engine is started.

What happens when you put the throttle on a motorcycle?

The bike revs it self pretty high. Not to redline but it gets up there. When the throttle is applied it seems like it revs sometimes but not how a normal motorcycle would.

What does blip throttle and Revs hang mean?

Blip throttle and revs hang = rich/lean? are adjusted towards the lean side. If on the other hand a quick blip returning to the idle rpm the bike is running a little rich. Does anyone know of the underlying mechanism to this analysis?

What’s the throttle response on a 2009 Harley?

2009 Harley Ultra Classic w/25K no past problems in the past, but on 07-12-14. I had a problem with what I found out and is called “Limp Mode”! no throttle response at all other than running at idle.
