If this involves road testing, keep it legal and safe. A quiet car park teaches more than a panic run down a public road. That is how I would approach Suzuki DR650 lost power while riding and never restarted before spending money.
Would you test Suzuki DR650 lost power while riding and never restarted cold first, or wait until the symptom appears hot? Mine changes after about twenty minutes.
Thomas Spagnoli: workshop approach for Suzuki DR650 lost power while riding and never restarted
Before buying anything for Suzuki DR650 lost power while riding and never restarted, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.
The best next step is the one that can prove something. A test that only creates another guess is just a more expensive guess.
For students, this is exactly why I built the free Motorcycle Mechanics Course on this platform. It teaches the method behind fuel, spark, compression, charging, diagnostics and safe workshop habits, so problems like Suzuki DR650 lost power while riding and never restarted become a sequence instead of a guess.
Add the model year, mileage, recent work and what changed before the problem started. With that, the next test becomes much easier to choose.
I will test this in order and report back. This is already clearer than the usual 'replace everything' advice. This should make the Suzuki DR650 lost power while riding and never restarted thread useful for the next person too.
