Just to be clear if you were to turn the same corner but at a lower speed no issue?
if you were to turn the same radius and speed but the other direction no problem?
1st question relates to possibility that a wire is being affected by the turning, (mechanically moving or being rubbed on by a suspension or other moving part)
2nd question relates to carb being the issue. I would expect that it would not matter left or right turn if it was fuel system related BUT it might.
