Hi there guys over the years i have managed to keep the airbox in relativly good condition seeing as I am not able to open it or remove the air filter due to the Air box being brocken however I have pushed it far along and it badly needs replacing now, Buying a new airbox is not an option as they are not avalable.

I would like to switch to a high flow air filter or cone filters against my better judgment as this is my only options.

I understand that I will need to increase the jet sizes and or air fuel mixture screws along with the air cone filter due to there being a larger air intake volume however I am not exatly sure what parts I will need ( Injectors?)

Please help As it is now getting hectic.And very important that i replace this the bike is not getting enough air flow and its messing around with everything
