Step-by-Step Derestricting Instructions
1. Remove the Airbox Restriction:
- Locate the airbox, usually located under the fuel tank.
- Remove the screws or bolts holding the airbox cover in place.
- Identify the airbox restrictor, typically a plastic or metal plate.
- Carefully remove the restrictor and discard it.
2. Replace the Exhaust:
- Purchase an aftermarket exhaust system that is specifically designed for your Triumph Street Triple 660.
- Remove the stock exhaust system by loosening the bolts and clamps.
- Install the aftermarket exhaust system according to the manufacturer’s instructions.
3. Reprogram the ECU:
- The ECU (Electronic Control Unit) controls the engine’s performance.
- You can reprogram the ECU using a tuning device, such as a Dynojet Power Commander or a Rapid Bike EVO.
- Follow the device’s instructions to upload a new map that optimizes the engine’s performance for the derestricted components.
4. Remove the Throttle Stop:
- Locate the throttle stop, usually a screw or bolt located on the throttle body.
- Carefully remove the throttle stop and discard it.
- This will allow the throttle to open fully, giving you access to the motorcycle’s full power range.
5. Check and Adjust Fuel Mixture:
- After replacing the exhaust and reprogramming the ECU, it’s crucial to check and adjust the fuel mixture.
- Use a fuel mixture analyzer or consult a professional mechanic to ensure the bike is running at the optimal air-fuel ratio.
6. Test Ride and Fine-Tune:
- Once the derestricting process is complete, take the bike for a test ride.
- Pay attention to the engine’s performance, throttle response, and overall feel.
- Make any necessary fine-tuning adjustments to the ECU or other components to optimize the motorcycle’s performance.
Additional Considerations
- Warranty: Derestricting your motorcycle may void the manufacturer’s warranty. Consider this carefully before proceeding.
- Emissions Compliance: Check local laws and regulations regarding emissions standards before derestricting your motorcycle.
- Professional Assistance: If you are not comfortable performing the derestricting process yourself, seek assistance from a qualified mechanic.
