Ok the power on my cbr900 seems to be fluctuating on and off (kinda like WAAAAAAA....woooo oooo WAAAAAAAA wooooo) while pretty much wide open in 5th or 6th gear. Now the only thing that has been changed is the 2 little air tubes connected to the air box are gone, cause other stuff is under the tank now.... so could it be that she isn't getting enough air??? If so has anyone just cut extra holes in the front of the air box??? That’s what I'm planning on doing.
Oh and I know all the normal stuff is good ie… plugs new, carbs clean, k&n filter clean.
