Cant figure out why my Busa is hesitating between 4K and 5k rpm. Doesn't matter the gear or the speed. Once it clears 5k the bike takes off and before 4K it has all the power also. Mods are a yoshi full exhaust, power commander and restricter delete. I'm going to be doing the air box mod and ram air scoops this weekend. Anyone have an idea what the problem is?
