Help thread: Suzuki DL650 V-Strom fuel cap vacuum sound and highway starvation
This thread is for Suzuki DL650 V-Strom fuel cap vacuum sound and highway starvation. I want to understand the logic, not just throw a shiny part at the bike and hope it feels appreciated. The symptom is intermittent, which makes it extra irritating. It behaves perfectly the moment I decide to show somebody else.

Thomas Spagnoli: workshop approach for Suzuki DL650 V-Strom fuel cap vacuum sound and highway starvation
My workshop rule for Suzuki DL650 V-Strom fuel cap vacuum sound and highway starvation 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 Suzuki DL650 V-Strom fuel cap vacuum sound and highway starvation 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.
