4. Installation Guide
The Puig Engine Spoiler is designed for a bolt-on installation. Specific steps may vary slightly depending on your motorcycle's exact configuration. Always refer to the detailed instructions provided with the product packaging for precise, model-specific steps.
- Preparation: Park the motorcycle on a level surface and ensure it is stable. Allow the engine and exhaust to cool completely.
- Identify Mounting Points: Locate the designated mounting points on the motorcycle frame or engine area. These are typically pre-existing bolt holes.
- Assemble Components: If the spoiler consists of multiple pieces, assemble them loosely according to the included diagrams.
- Position the Spoiler: Carefully position the engine spoiler against the motorcycle, aligning the mounting holes.
- Secure with Fasteners: Insert the provided bolts and washers into the mounting points. Hand-tighten all fasteners initially.
- Final Tightening: Once all fasteners are in place and the spoiler is correctly aligned, progressively tighten them to the recommended torque specifications. Ensure even pressure and a secure fit.
- Final Check: Double-check all bolts for tightness and ensure there is no interference with any moving parts or other motorcycle components.

5. Post-Installation Check
After installation, perform the following checks:
- Visual Inspection: Ensure the engine spoiler is firmly attached and does not wobble or move.
- Clearance: Verify that the spoiler does not obstruct any motorcycle controls, exhaust components, or moving parts (e.g., front wheel, suspension).
- Test Ride: Conduct a short, low-speed test ride to confirm proper fitment and absence of any unusual noises or vibrations.
6. Maintenance
To ensure the longevity and appearance of your Puig Engine Spoiler, follow these maintenance guidelines:
- Cleaning: Clean the spoiler regularly with mild soap and water. Avoid abrasive cleaners or solvents that could damage the ABS or aluminum finish.
- Inspection: Periodically inspect all mounting bolts for tightness. Vibrations from riding can sometimes cause fasteners to loosen over time.
- Damage Check: Examine the spoiler for any signs of damage, cracks, or excessive wear, especially after impacts or prolonged use.
- Material Properties: The spoiler is constructed from high-resistance ABS and aluminum materials, designed to withstand impacts and UV rays.
7. Troubleshooting
If you encounter any issues during or after installation:
- Loose Fitment: Re-check all mounting bolts to ensure they are tightened to the correct specifications.
- Interference: If the spoiler interferes with other motorcycle parts, re-evaluate the positioning and ensure all components are correctly aligned.
- Unusual Noises: Investigate any new noises or vibrations. This could indicate a loose component or improper installation.
- Contact Support: If problems persist, refer to the detailed instructions provided with the product or contact Puig customer support for assistance.
