Thomas Spagnoli: workshop approach for Suzuki Bandit 1200 leak down test before blaming ECU
Before buying anything for Suzuki Bandit 1200 leak down test before blaming ECU, 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.
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 Bandit 1200 leak down test before blaming ECU 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.
