In preparation for installing a monoshock on my 1982 GPZ1100, I have moved the battery upwards. This has caused me to have to remove the center chamber of my airbox. I am looking for a piece of ductwork to make up for the center chamber that was there to connect the filter housing to the surge chamber. I would like to keep as much of the original airbox as possible. I like the look of it. The OD going into the surge tank is 2-5/8" and the ID going onto the filter housing is 2-3/4".
