FAQ: How To Adjust Throttle Cable On Harley Davidson?

Why does my Harley have 2 throttle cables?

A push/pull throttle cable is an upgrade to the old standard single throttle cable linkage. The throttle grip works on the carburettors when twisting/throttling up and when releasing/throttling down. The second cable pulls the carb closed so it isn’t stuck wide open.

Why is my throttle sticking on my Harley?

A sticky throttle could be caused by worn cables, lack of lubrication in the cables or the cable getting bound up somewhere in the mechanism. Or it can be caused by an issue with the carburetor or EFI. If the screws in the throttle housing are too tight it could cause the cable to stick.

Are throttle cables universal?

In today’s modern vehicles, throttle cables are obsolete with the widespread use of drive-by-wire throttle pedal assemblies. Our universal throttle cable offerings fit most any application or engine type and mounting location.

How do throttle cables work?

An accelerator cable, sometimes called throttle cable, is a metal braided cable that serves as a mechanical link between the gas pedal and the engine’s throttle plate. When the gas pedal is pressed, the cable is pulled and opens the throttle. The most common way that accelerator cables fail is that they break.

What is the throttle friction screw?

Adjust the throttle friction with the adjustment screw that’s typically below the throttle on the tiller. The idea is to set the throttle friction so that it’s not too much effort holding a speed but not so much that you can’t make quick adjustments in response to changing operating conditions.

How can I make my throttle more responsive?

More air volume and speed is a surefire way to increase horsepower and throttle response at any given RPM. It is easy to achieve this at high RPM when the engine sucks in substantial amounts of air on its own.

Why is my throttle cable loose?

In order to fix a loose or tight throttle cable, you’ll need to turn this nut. Place the open ended wrench over the throttle body adjustment nut, and turn the nut either clockwise or counterclockwise until there is about 1/4 inch play in the tension of the throttle cable.

How do you unstick a throttle?

Pour penetrating oil into the cable (Photo 1). Grab the inner cable with pliers and work it up and down to loosen it. When the cable moves freely and all the penetrating oil has drained out, squirt silicone lubricant into the funnel to keep the cable sliding freely. Reinstall the cable (Photo 2).
