GSXR Pair Mod

[Cakes206]

As most of you may know the crank case on a GSXR is vented through the air box. This is mainly for emissions control. The problem with venting the crank case into the air box is oil mist can/will travel into the air box, past the filter and into the air/fuel mixture, weakening the charge detonation. The Pair Mod bypasses the air box and vents though the exhaust. This will not only eliminate all chances of oil mist getting into and through the air box...but will also create negative pressure within the crank case...wich is always good for a pony or two...

This is how to do the pair mod on an 02 GSXR 750. The applications for the same generation 600 and 1K's is relatively the same.

Take off the tank. Take off the air box. Take off the hose that connects the crank case cover to the air box and cap off the opening left behind on the air box.

Pic 1 This is where the pair valve sits(removed in pic)
Pic 2 Size and part # of hose from Home Depot
Pic 3 "T" connector also from HD
Pic 4 Cap off the vacuume hose with a slightly larger screw. I don't recomend cutting the hose, just incase you want to turn it back to stock. You can see the hose comming out just by the #4 TB.
Pic 5 Crank case cover where hose connected to air box WAS.
Pic 6 Attach one end of NEW hose to crank case cover.
Pic 7 Connect other end to "T" connector...Your done.
Pic 8 Your end result should look like this...plain and simple. The clamps I had gotten were a tad to small so I used zip ties for now. But as tight as that hose is...it ain't goin nowhere...
