Joe V's Airbox and Base Plate Modifications

This mod definately works but is not a patch on taking the entire lid off. This page is Joe's original mod with extra pics taken from another site.

AIRBOX

1. Remove the air box lid
2. Turn the lid upside down
3. You will see the 2 air intake valves. These will be removed.
4. Slide the actuator rods out of the flappers (indicated in lid-1 jpeg)
5. Turn the lid over and locate the intake air control valve actuators
(indicated in lid-2 jpeg)
6. Turn the actuators and remove from the air box lid .
7. Take one of the vacuum lines that run to the actuators and form a loop to the
"t" fitting in the vacuum line.
8. Now all that is left to do to the lid is to seal the holes left by the vacuum
actuators. On the bike that I have done, I use fiberglass disks, washers really,
with gasket maker, and place one disk on the inside of the opening and one disk
on the outside of the opening and secure with a 1/4" bolt and self-locking nut.
It is important to seal these openings.

1. Remove the air filter (illustrated in figure 1)
2. Remove the base plate by removing the screws (indicated in figure-2)
3. Cut away the material outlines in yellow in figures 3 and 4. Be careful not
to cut the towers that the filter bolts to. Also if you turn the base plate up
side down you will see that there is a lip that seals to the bottom of the base
plate, be careful not to cut this.
4. Reinstall the base plate and filter. Reinstall the air box lid. Check the TPS
adjustment. Re-map to +5 +10 +5 and you are done. You should now be able to
reach red line in 6th gear.

With extra pics

The first step is to remove the airbox lid and take off the flappers and valve actuators.

 
The next phase is to plug the actuator holes. I sandwiched the hole in the lid with two washers, a bolt and locking nut. Also, using some sealant to ensure it's airtight.


The pictures below show the airbox without the baseplate. As you can see the holes where the ram air enters are evident. I modified the baseplate to open these holes up. Joe's instructions are modifying the baseplate even more and removing the "wings" remaining on the plate, with the exception of the screw holes. I don't know there is an obvious benefit to doing this as the ram air will not enter through there anyway. If you study the picture, you'll see what I mean.

The next set of pictures show the airbox with the modified baseplate and filter installed. It also shows you the lid installed again. Of course the remaining step was to loop the hose at the T piece.
