runner Posted December 26, 2007 Share Posted December 26, 2007 Good information! I will clip mine closed and see how it helps out the power. In theory, you could also likely use a mini u-bolt and cut off ar-irflow that way as well. Now if I can just find one of those clips at my dealer...

Yes, it will aid in obtaining correct A/F ratios if you're dyno tuning, but simply disabling or removing the system gets you no appreciable increase in HP.

I am running a 97 w/B&B exhaust(yeah that's right, i said B&. It has been tuned for the pipes ( so I was told). After reading about all this, I was convinced it would free horsepower. What gives? Is the decrease in backpressure and increase in intake flow all just a myth? Damn, seemed like everyone agreed on this one! :icon_wall: Quote Link to comment Share on other sites More sharing options...
Redbird Posted December 28, 2007 Share Posted December 28, 2007 Many of the posts early in this thread were tongue in cheek, some may not have understood that and I can understand the confusion. Eric's comments on colder, denser air causing more back pressure are most likely true, he's a sharp guy who has played around with the exhaust and A/F ratios on the XX as much as anyone- but gains to be had by eliminating that cold air would be infinitesimal, IMO.

Pete in PA Posted December 29, 2007 Share Posted December 29, 2007 Now to clarify, DUH! If you give a bike 20 HP the steering gets quicker! Now removing tounge from cheek, no power gain, just cleans up top end for easier valve cover or spark plug removal. Might lessen backfire out pipes on decell. I'm a cheap bastard but I still bought the plates since they can remain in place to remove the valve cover. Thanks Red J! Quote Link to comment Share on other sites More sharing options...

Hooplehead Posted December 30, 2007 Share Posted December 30, 2007 damn, you guys got me! they are D&D. Can I pawn that one off as a typo, or is it just too obvious I was on the sauce and smoke the day I typed that? Anyhow, I guess I'll leave the pair alone for now. If the gains are minimal and my riding ability is also minimal, then I guess they'd cancel each other out. Thanks guys. -Shane Quote Link to comment Share on other sites More sharing options...
BackStreet Posted January 4, 2008 Share Posted January 4, 2008 I have a nice condo to sell you in Florida. With 20 hp extra you can do 200mph and get there before you left with the time warp in the worm hole….. Quote Link to comment Share on other sites More sharing options...
Silverbird2 Posted February 10, 2009 Share Posted February 10, 2009 Step 0. Reed Valve Cover - before modification Step 1. Cut away the bulge at the top. Takes about 30 seconds with a cut-off wheel on a dremel tool. Step 2A. 1/2" copper plug. $3.00 in the plumbing section of Lowes. Step 2B. Heat copper plug with a propane torch and tap over the snout. It's a very tight fit. I couldn't get the cap on without heating it. Step 3. Cap the airbox opening that feeds the PAIR valve Step 4. Connect the two vacuum ports on the carbs that supply vacuum to the PAIR valve. Step 5. Go destroy the environment just so you can have a cleaner cylinder head. So on a fuel injected bike where should i look for the vacuum supply that is shown connected together on the carbs? Quote Link to comment Share on other sites More sharing options...
Skull Posted February 13, 2009 Share Posted February 13, 2009 So on a fuel injected bike where should i look for the vacuum supply that is shown connected together on the carbs? On the other end of the hose connected to the PAIR valve. Quote Link to comment Share on other sites More sharing options...
