Thomas Spagnoli: workshop approach for Versys 650 starts cold then stalls at idle

Before buying anything for Versys 650 starts cold then stalls at idle, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.

1. Define the condition: cold, hot, idle, load, rain, bumps, full lock, after refuel, or after charging.
2. Test the basics first: battery, grounds, fuel quality, connectors, vacuum leaks, air filter and recent work.
3. If intermittent, move the loom gently while monitoring the symptom. Do not pull hard; you are looking for clues, not creating new faults.
4. Replace parts only when a measurement or repeatable test points to them.

The best next step is the one that can prove something. A test that only creates another guess is just a more expensive guess.

Would you test Versys 650 starts cold then stalls at idle cold first, or wait until the symptom appears hot? Mine changes after about twenty minutes.

Thanks everyone. I wrote the checks down and I will come back with results, not just vibes and panic. At least now I know what I am trying to prove before spending money.
