Shop parts for a 2015 Cobra CX65 Dirt Bike.
The 2015 Cobra CX65 is a specialized competition bike engineered for young racers, emphasizing peak performance and precise maintenance. Keeping the air filter clean and well-oiled is critical for both the engine's health and race-winning performance, especially considering the dust and debris typical on motocross tracks. This guide provides step-by-step, MotoSport-exclusive instructions tailored for your CX65.
Before You Begin: What CX65 Owners Need to Know
- Only use high quality water-resistant foam filter oil, as inconsistent oiling impacts carburetor jetting and can damage your engine.
- The air filter is a crucial point of defense; improper cleaning or installation can let dirt into the engine, causing expensive damage.
- MotoSport recommends changing or cleaning the filter after every moto for the CX65 due to high performance demands and exposure to dust. Carry multiple pre-oiled filters for convenience between practice sessions and races.
Tools & Products Needed
- 5 mm hex key (Allen wrench)
- Nonflammable solvent (diesel fuel, mineral spirits, or kerosene preferred—never gasoline)
- Mild hot soapy water
- High quality water-resistant foam filter oil
- Clean rags
- Disposable gloves
Removing the Air Filter
- Remove the seat using the 5 mm hex key.
- Unhook the air filter wire from its perch.
- Carefully lift the air filter and its frame out of the airbox, taking care not to shake dirt into the intake tract.
Cleaning Procedure
- Soak the air filter in a nonflammable solvent to dissolve old oil. Gently squeeze (do not wring) the filter to release debris and oil.
- Wash the filter in hot, soapy water to fully remove residual dirt. Rinse thoroughly.
- Allow the filter to dry completely before oiling.
Oiling & Reinstallation
- Saturate the filter with high quality water-resistant foam filter oil. Massage oil evenly throughout all foam surfaces, then squeeze out excess oil; uneven oil application can impact carburetor tuning.
- Reinstall the filter with frame, ensuring the lip of the filter cage seats tightly in its airbox receptacle. Double-check that the filter is pressed in tight at the bottom to avoid leaks.
- Reinstall the holding wire and air filter cap. Replace the seat securely.
Replacement Tips
- If the filter is torn, brittle, or won't clean up, replace immediately to avoid engine damage.
- Frequent racers should keep multiple MotoSport-supplied filters for fast between-moto swaps.
Model-Specific Advice for 2015 Cobra CX65 Owners
- This bike is built for riders under 110 lbs. on closed course competition–its air intake system is designed for maximum airflow, but is more vulnerable to off-road debris than a street bike.
- Do not run automotive engine oil in the transmission or clutch; only use manufacturer-recommended lubricants.
- Routine filter cleaning protects the powerful 65cc engine, ensuring consistent throttle response and preventing race-day failures.
