PAIR, Variable Air Intake Valve and Snorkel Modification


Ease to do and it smoothens out the power band.  This will give you a little less than a horse of extra power, it will reduce throttle chop and help the flat spot between 5,000 and 5,500 RPM.  The dyno before and after are on VFR Discussion http://www.vfrdiscussion.com/forum/index.php/topic/55729-vfr-track-bike/Lift the gas tank as you would to replace the air filter.  Remove the vacuum hose from the  variable air intake and plug both the tube and the valve using a rubber end caps from your standard wire shelving unit (just go to Lowes and in the shelving isle you will see them).  I also pulled out the snorkel for the air box (you just pull it out).  Then disconnect the PAIR Valve wiring harness, (http://johnny.chadda.se/article/pair-and-flapper-mod-with-bonus-snorkel-mod-for-vfr), done.  Also on the air box you will see a rubber snorkel, you can remove that by just pulling it out while twisting a little.  This will improve air intake, see below to improve exhaust flow.  So far MPG is the same but the mid-range is much smoother, YMMV.
