Proprietary MotoSport Method: Changing the Coolant
-
Preparation
- Let the bike cool completely before starting—never open the cooling system when hot.
- Set the bike on a level surface with a drain pan beneath the engine area.
-
Access the Radiator System
- Remove the seat and lift away any plastics as needed to reach the radiator cap. On the TXT RACING 250, the radiator cap is located beneath the fuel tank.
- Fold up the quick release on the fuel tank, turn it counterclockwise, and pull it upward to remove the tank for full access (reference manual procedure).
-
Drain the Coolant
- Locate the lowest coolant hose connection or designated drain bolt on the water pump cover—this is typically on the right side of the engine. Loosen or remove the drain bolt; coolant will begin to flow out.
- Allow all coolant to thoroughly drain into your pan.
- Check and clean the drain bolt before reinstalling it securely.
-
Flush if Needed
- If the previous coolant was dirty or contaminated, flush the system using distilled water before final filling.
- Repeat the draining process to ensure only clean water remains before fully draining and continuing.
-
Refill the Coolant
- Pour fresh, high-quality motorcycle coolant slowly into the radiator until full. For best protection, use a 50/50 mixture of antifreeze and distilled water unless your coolant comes premixed.
- Agitate the bike gently or squeeze the hoses to help purge trapped air.
- Check the level and top off as needed. The system should be completely filled with no voids.
-
Bleed the System
- Start the engine and let it idle briefly with the radiator cap off. Watch for bubbles—this indicates air escaping the system. Top off the coolant as needed during this process.
- Once the coolant stabilizes and no more air bubbles rise, close the system with the cap.
-
Reinstall Fuel Tank & Plastics
- Install the fuel tank quick release (GAS GAS label facing upward), turning clockwise until firmly closed.
- Reattach the seat and any plastics removed earlier.
-
Final Checks
- Start the engine again, bring it up to operating temperature, and inspect for leaks under pressure.
- After cooling, recheck coolant level and top off if needed.
- If coolant contacted your clothing, change immediately—coolant is toxic.
Additional Tips for TXT RACING 250 Owners
- Inspect hoses and radiator regularly – the flexible bodywork means impacts can occur. Look for cracks or leaks after tough rides.
- Use only motorcycle-specific coolant – avoid automotive coolants as they may not protect specialized components or seals on your trials bike.
- Keep vent hoses free of kinks – proper routing is critical for top cooling performance.
- Check service intervals – refer to your owner's manual for recommended coolant change intervals.
