I'm pretty sure this is incorrect. You don't need to re-tune if you put in breathers. Someone agree or disagree.
how it was with mine. The tune was all jacked up after i put this on with the air/fuel. Did some adjusting and it is a perfect line of 11.50 now. I didn't change anything else do cause my air/fuel to drop to a 10.
