In relation to the fueling issue, I have been contemplating the effect of atmospheric pressure on the numerous vents on the carbs, on the stock setup they were vented into the air box generating negative pressure under acceleration, I've consitered a passive emmisions system in which a vented oil catch can (possably containing charcol) accumulates and vents into the intake through a port in a coupling between the air filter and carbs.
Has anyone had any issues regarding pressure diffrences in the ventaliation on the carbs??
Should I worry about this?
I've heard some say to block them which sounds foolish.
