Help thread: Lexmoto LXR 125 crank sensor hot failure causes no spark until cool

I am trying to build a sane checklist for Lexmoto LXR 125 crank sensor hot failure causes no spark until cool 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 Lexmoto LXR 125 crank sensor hot failure causes no spark until cool, I would write down the current condition first. Model, year, mileage, recent work, and exact symptom will save ten posts of guessing.

If you can, post a photo of the part, connector, plug color, or dash message. A decent photo can save half a page of wrong assumptions. That is how I would approach Lexmoto LXR 125 crank sensor hot failure causes no spark until cool before spending money.

Thomas Spagnoli: workshop approach for Lexmoto LXR 125 crank sensor hot failure causes no spark until cool

For Lexmoto LXR 125 crank sensor hot failure causes no spark until cool, 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. 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.

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

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 Lexmoto LXR 125 crank sensor hot failure causes no spark until cool 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.
