Thomas Spagnoli: workshop approach for Triumph Speed Triple 1050 pump prime normal but secondary injector rail has no pressure
My workshop rule for Triumph Speed Triple 1050 pump prime normal but secondary injector rail has no pressure is simple: prove the basic condition first, then decide whether the clever part is actually needed.
If the result changes hot versus cold, or under load versus idle, write that down. Those conditions are not noise; they are clues.
This is also the kind of method I teach in the free Motorcycle Mechanics Course here on the platform: observe, measure, confirm, repair, then test again. It is much easier to solve Triumph Speed Triple 1050 pump prime normal but secondary injector rail has no pressure when the process is clear.
If you report back, include the measured values, not only whether it felt better. Numbers make the thread useful for the next rider too.
I have enough to work with now. No heroic parts cannon today, just tests, notes, and hopefully fewer dramatic noises. I like that this turned into a checklist instead of a guessing contest.
