Hey Guys; Just started a project with my CB 125E. I want to get rid of the air box and use a pod filter but there is a tube that goes from the air box to a vacuum diaphragm thingy then a tube that returns to the engines cam cover, (I have no idea of it's purpose) Is this going to be a problem?.

The air injection is a little valve that opens when you back off the throttle and allows air to enter the exhaust which helps to burn any unburnt fuel in the exhaust reducing emissions. The valve lives up under the tank behind the engine head. It has a small tube that connects betwween the valve and the inlet manifold and two large tubes that connect To the valve. One tube goes to the airfilter and the other goes to the chrome on the cam cover, I unbolted the valve and sealed off the connecting points. The chrome tube on the cam cover I cut short and crimped and sealed it. Makes it a little easier to remove the cam cover for valve adjustments.
It kind of sounds as though it is what you are asking about.
