Why do Harleys have two throttle cables? A push/pull throttle cable is an upgrade to the old standard single throttle cable linkage.

What does the idle cable do on a Harley? Premium Member.

What is Harley throttle by wire?

Throttle by wire is a simple, potentiometer style (think volume switch) design that when the throttle tube is moved, the values are calculated, and an electrical impulse is sent to the throttlebody, and a small electric motor moves the throttle plate, rather than manual linkage via cables.

What happens if throttle cable breaks?

When the gas pedal is pressed, the cable is pulled and opens the throttle. If the cable breaks, or comes out of adjustment far enough, it can affect the drivability of the vehicle to the point where the car will not be drivable until the problem is addressed.

Is throttle by wire good?

Benefits of Throttle-By-Wire:

Traction and Stability Control: With throttle-by-wire, it is easier to shut down the power than to fight it with the brakes. Throttle-by-wire creates harmony between the throttle angle, ignition and fuel, which allows the engine to create more torque and power.

What does tightening the throttle cable do?

The tightness of the accelerator, or throttle, cable on any vehicle is important. If the cable is tightened too much, the car will not idle properly and consume fuel quickly. If the cable is too loose, the car will respond slowly when you press the gas pedal.

Why is my throttle cable stuck?

Debris can get caught between the throttle tube and the handlebar, and cause it to stick. Another culprit happens at the other end of the throttle cable. Down at the carburetor, the cable gets stuck, so even when you rotate the grip to ease up on the throttle, it still stays open.

What does adjusting the throttle cable do?

Adjusting Throttle Free Play:

The adjusters effectively lengthen or shorten the cable outer, which in turn changes the length of the inner cable that’s doing the pulling.
