Shop parts for a 2018 GAS GAS TXT-GP-300 Dirt Bike.
The 2018 GAS GAS TXT-GP-300 is a high-performance trials bike engineered for precise control, torque delivery, and technical maneuvering. Keeping your air filter clean and in top shape is essential for optimal performance, engine protection, and reliability on demanding sections and terrain specific to trials riding.
Why Air Filter Maintenance is Critical
- Dust & debris commonly encountered on trials courses can rapidly clog an air filter, risking poor performance or engine damage.
- Dirty or degraded filters reduce air flow, leading to rough running, increased fuel consumption, and premature engine wear.
- This model's two-stroke engine is especially sensitive—consistent airflow is crucial for proper fuel/air mixture and smooth power delivery.
Frequency – When Should You Clean or Replace?
- Inspect the air filter after each ride, and always after riding in dusty or wet conditions.
- For competitive or regular riders, plan to clean the filter after every significant outing.
- Replace the filter if it shows signs of damage, wear, or inability to come clean, typically every few months of regular use.
How to Remove the Air Filter on the 2018 GAS GAS TXT-GP-300
- Ensure the bike is cool and parked securely on a stand.
- Remove the seat and side panel to access the airbox.
- Carefully detach the air filter cage or holder and gently extract the air filter element.
- Inspect the intake tract for any loose dirt or debris—do not let dirt fall into the intake.
Cleaning Process for the Air Filter
- Lightly tap the filter to dislodge loose debris; never use compressed air directly as it can damage the filter.
- Wash the foam filter thoroughly in a dedicated air filter cleaning solution or a mild detergent. Never use gasoline; it degrades foam and glue joints.
- Rinse well with clean water, gently squeeze (do not wring), and allow to air dry completely.
- Once dry, apply appropriate air filter oil evenly. Work it into the foam for a uniform coat—this traps fine dust.
- Wipe excess oil and check for rips, tears, or hardening. If any of these are present, replace immediately.
Reinstallation Steps
- Clean the air filter cage, making sure it's free of old oil or debris.
- Carefully fit the cleaned, oiled filter onto its cage, ensuring a complete seal around the airbox.
- Inspect and clean the sealing surface in the airbox, then install the filter and secure it as per the manual's instruction.
- Reinstall the side panels and seat after verifying proper fitment.
Pro Tips – TXT-GP-300 Owners
- This model's airbox design offers easy access but also has tight sealing requirements—double-check there is no misalignment or pinching of the filter edge during installation.
- If using aftermarket filters or filter skins, ensure they are made for the TXT-GP-300 as improper fit can reduce protection and performance.
- The two-stroke engine is particularly sensitive to air leaks; always inspect and maintain the airbox cover and filter clamp points.
When to Replace the Air Filter
- If the foam is brittle, seamed, torn, or the glue joints are failing.
- When cleaning fails to restore flexibility, or excessive staining is present.
- Always keep a spare, clean and pre-oiled filter ready for quick swaps on comp weekends or dusty trails.
Final Tips
- Routinely inspect related intake hardware, including the airboot, clamps, and intake tract, to prevent secondary dirt intrusion.
- Log every filter change or cleaning to keep your maintenance schedule on track.
- Follow up with full checks of the intake tract and carburetor if you ever discover a filter was run unsealed or damaged.
