HOW TO FIX AND ADJUST MOTORCYCLE THROTTLE CABLES

HOW TO FIX AND ADJUST MOTORCYCLE THROTTLE CABLESMotorcycle throttle cables usually consist of two steel cables that run from the grip of the throttle to the engine, to open and close the carburetor. Drivers use these two cables, the front cable and the idle-hand throttle cable, to accelerate the bike, the same as a pedal is used to accelerate a car. Because these cables are so vital to a motorcycle’s function, it’s necessary to know how to adjust and fix them when they stick. Learn how to below.

Step 2 – Loosen Cables

Use wrenches on the adjusters to loosen the throttle cables. The adjusters look like steel nuts around the cables. Back the screws all the way out.

Step 3 – Remove Switch Housing

The switch housing looks like a black box on the handlebar. Use a socket wrench with the appropriate bit to unscrew the bolt found underneath the switch housing. Once the bolt is out, put it into a safe place, and open up the switch-housing box.

Step 4 – Apply Lube

Next, apply a lubricant made into the cable end. You can find these lubricants online or at any after-market stores or motorcycle dealerships. Squeeze a few drops into the front cable and the idle-hand throttle cable located behind it.

Step 5 – Attach the Switch Housing

Re-attach the switch-housing box with the socket wrench. Then, open the throttle all the way.

Step 6 – Level out the Carburetor

With the throttle open all the way, adjust the throttle cable closest to the bike all the way out. As it is close to being all the way out, keep adjusting it until the butterfly on the carburetor or intake manifold is completely leveled.

Step 7 – Test Your Work

Lastly, take the bike off the lift and put it on its kickstand. Turn the handlebars all the way to the left, and then open the throttle all the way. The throttle should snap back, making an audible snapping noise. Repeat this test by turning the handlebars all the way to the right, then to the center, both times opening the throttle and listening for a snap.

If it does not snap back,do adjust the throttle cable a little bit more until it successfully snaps. Because they are very vital to safely ride your motorcycle, change replace your cables if one is broken or needs to be repaired.
