Thomas Spagnoli: workshop approach for Yamaha R1 2007 fuel pump relay output powers pump and injectors question

For Yamaha R1 2007 fuel pump relay output powers pump and injectors question, I would slow the job down for ten minutes and make the evidence visible. Guessing feels fast, but it usually makes the repair longer.

1. Make the motorcycle mechanically healthy first: compression, valve clearance, plug, filter, fuel delivery, chain/CVT and brakes.
2. Choose changes that match the use case. City scooter, commuter, trail bike and highway bike need different compromises.
3. Confirm legal and insurance rules before derestriction, ECU work, exhaust changes or power kits.
4. Change one thing at a time and keep the original parts until the result is proven reliable.

Keep the original setup in mind. Many faults appear after a small change, and the change is often more useful than the symptom.
