FAQs
Is this silencer street legal?
This silencer is designed for off-road and performance use. Please check your local vehicle regulations regarding aftermarket exhausts.
Do I need to change my carburetor settings?
While it can run on stock settings, adjusting the jetting is highly recommended to achieve the best performance and ensure engine longevity.
Does this include the expansion chamber?
No, this product is the silencer section only. It is designed to work with the standard or compatible aftermarket pipes.
How do I maintain the polished finish?
Clean it regularly with a soft cloth and a non-abrasive aluminum cleaner to maintain its appearance and prevent corrosion.
Is it difficult to install?
It is designed as a direct replacement, making it a simple DIY task for those with basic mechanical knowledge and standard hand tools.
Troubleshooting
Visible exhaust leak at the connection point
Ensure the connection is fully seated and consider using a high-temperature exhaust sealant to create a tighter seal.
Engine feels hesitant or sluggish at certain RPMs
This is likely a sign of a lean or rich fuel mixture. Adjust your main jet or pilot jet settings to match the increased airflow.
Excessive vibration or rattling
Verify that the CNC machined bracket is tightened correctly and that the silencer is not making contact with the frame or swingarm.

Setup, Compatibility & Care
Installation of the DEPK2903 is straightforward, as it is designed specifically for the Kawasaki KMX125. Ensure the engine is completely cool before starting. Remove the stock silencer, taking care to preserve the original mounting hardware if necessary. Slide the DEP silencer onto the stinger, ensuring a snug fit at the connection point to prevent exhaust leaks.
For maintenance, the alloy body can be cleaned with mild soap and water to prevent oxidation. Avoid harsh chemicals that may strip the finish. Periodically check the mounting bracket bolts for tightness, as engine vibrations can loosen fasteners over time. We highly recommend checking your spark plug color after installation to determine if a change in carburetor jetting is necessary to compensate for the improved airflow.
