i just put a gytr foam filter and billit air filter adaptor plate on my 660, havent tried to ride it yet but i just wanted to know if i need to do anything to the carbs. ordered a hmf but they fu*ked up the order and are going to take for ever so im going to ride it like it is for now.

 

If you increase airflow into the engine, you need to increase fuel flow.

 

how? which screw do i turn on the carbs to increace the fuel flow?

 

richening up your idle mixture (fuel screws) probably wont do it. Unless you're still running a full stock airbox with lid and snorkle you're going to need new mains. If you are going to ride it just richen up the fuel screws and leave the stock airbox intact until you get your pipe, which shouldnt take more than a week.
