Help thread: KTM Duke 690 injectors connected allow crank but engine never catches

I am trying to build a sane checklist for KTM Duke 690 injectors connected allow crank but engine never catches before I start buying parts I may not need. I am collecting practical advice from people who actually test things, not just repeat what they saw in a two-minute video.

For KTM Duke 690 injectors connected allow crank but engine never catches, I would write down the current condition first. Model, year, mileage, recent work, and exact symptom will save ten posts of guessing.

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 KTM Duke 690 injectors connected allow crank but engine never catches before spending money.

Would you test KTM Duke 690 injectors connected allow crank but engine never catches cold first, or wait until the symptom appears hot? Mine changes after about twenty minutes.

Thomas Spagnoli: workshop approach for KTM Duke 690 injectors connected allow crank but engine never catches

Before buying anything for KTM Duke 690 injectors connected allow crank but engine never catches, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.

  1. Start with model, year, mileage, engine type, recent work and the exact symptom.
  2. Separate opinion from measurement: voltage, pressure, compression, plug condition, code history and visual evidence.
  3. Make a small checklist and tick it off in order. It is slower for five minutes and faster for the whole repair.
  4. When in doubt, return the machine to a known baseline before tuning or modifying.

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 KTM Duke 690 injectors connected allow crank but engine never catches 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.
