breaking up on hard accelleration
hope someone can help me with this new problem. last week i coastered the bike and put on a set of V/H cruisers. i set the air mixture screws to 2-1/2 turns. under normal light acceleration everything is cool but if i wind it out it strats breaking up & slight bucking is noted. seems like i' not getting gas quick enough to the cylinders. so should i rejet or just how far can i turn those screws out to get a richer mixture to the cylinders or is it something entirely different? thanks in advance to your replies.
i already cut the vent tube that goes in the right ear 45 degrees.
