    Was doing a bit of carb 42Mik tuning on my motor & started the bike without the carb backing plate and noticed a fair amount of flow/air coming out the head breathers. Never had run the bike without the carb backing plate before so question how much flow should one expect out the head breathers...normal or not?

    TIA,
