What should I expect when replacing both the air element and spark plug?

Replacing the air element restores proper airflow filtration and helps prevent abrasive dust entering the engine, while a fresh spark plug supports consistent ignition and efficient starting. Changing both items together is a time-efficient service step that can reduce run-in issues after heavy riding. Use basic hand tools and follow torque specs in the service manual when installing the spark plug.

• Cleaner air flow and reduced dust ingestion with new filter element
• Reliable spark and easier starts with the included plug
• Simple installation—airbox access and standard plug socket required
• Follow Yamaha torque and gap specs for safe installation

The boxed kit contains one replacement air element and one spark plug sized for the listed TTR125 variants. MOTO1988 references the OEM part to simplify identification and reduce misfit purchases. If you experience any issues, the seller provides 24-hour customer service and a one-year product support period for assistance.

How should I prepare and install the replacements safely?

Park the bike on level ground, cool the engine, and disconnect the battery if necessary for safety. Remove the airbox cover to access the filter, swap the element, then remove the old spark plug with a proper socket and install the new plug to the correct gap and torque. Reassemble components and run the engine to confirm proper idle and throttle response.

• Work on a cooled engine and use correct sockets and torque wrench
• Inspect airbox seals and clean surrounding area before installing
• Check and set spark plug gap per Yamaha specifications
• Test-run the bike after installation for proper performance
