Thomas Spagnoli: workshop approach for Suzuki Bandit 1200 wide open throttle bog after bigger main jet

For Suzuki Bandit 1200 wide open throttle bog after bigger main jet, 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. Confirm valve clearance and ignition health before blaming the carburetor.
2. Check fuel flow, float height, blocked pilot jet, air leaks, and the condition of the intake boot.
3. Return to a known baseline setting before tuning. Random screw positions make diagnosis muddy.
4. Read the plug after a proper test, not after two minutes of idling in the garage.

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