The throttle cable is among the motorcycle's most durable components. It rarely breaks or necessitates replacement, but it needs lubrication to maintain smooth operations and extend its service life. Once it gets dirty, the cable can stick. So, check your owner's manual and follow the manufacturer's recommended lubrication interval.
If it's now time to lubricate your motorcycle's throttle cable and you're doing the task all by yourself, here's a step-by-step guide to help you out:
What you'll need:
- Lubrication spray
- Needle nose pliers
- Cable lubrication tool
Step 1: Detach the throttle cable from the throttle lever.
Start off by loosening the jam or locking nut that secures the cable to the throttle lever. Once loose, unscrew the main cable adjustment assembly and disconnect it from the lever. You can do that by turning the entire cable to the left or right at about 90 degrees to make the throttle cable's end slip out of the lever.
Step 2: Disconnect the other end of the cable from the carburetor.
On the other end, the cable is attached to the carburetor and you have to detach these two components by turning the cable using the needle nose pliers. Once it's loose, take the cable out. In some cases, the cable is held in place by a screw and a mounting bracket. If this is the setup with your motorcycle, simply unbolt the retaining screw and take out the cable.
Step 3: Apply the degreaser.
Get the throttle cable lubrication tool and position it on the part of the cable that was connected to the throttle lever. Clean the cable properly by forcing the tool tight on it. The lubrication tool has a small hole, and that's where you should insert the nozzle of the degreaser. Spray generous amount of degreaser to effectively force dirt out of the cable's other end, thus cleaning the cable completely.
Tip: Some motorcycle degreasers can cause irritation once they get into your eyes. So be careful when using the degreaser and the lubrication tool.
Step 4: Lubricate the cable.
After cleaning the cable, do not remove the lubrication tool from it. Get the lubrication spray and insert its nozzle into the tool. Spray ample amount of lubricant and let it coat the cable.
Tip: Make sure that the lubricant you'll use is designed for throttle cables.
Step 5: Put the throttle cable back in place.
Re-install the cable. Once you're sure that it's snugly fitted in place, carefully run the cable back into the throttle lever. Secure the cable into the lever using the same retaining nut that you've removed a while ago.
Re-place the mounting bracket and tighten it in place. Fine-tune the tension of the newly lubricated cable by twisting the adjuster nut in the main cable adjustment assembly counterclockwise using a wrench. Finish off your DIY by tightening the locking or jam nut.
Tip: Be careful not to over-tighten the assembly's adjuster nut or else, you won't achieve the cable's proper tension.
