15 minute PAIR mod with pics!

It took me 15 minutes, but 5 of that was trying to get the damned tank cover back on, because the rubber gasket around the gas cap opening snags on the plastic tabs. The best way to do it is to spray a couple drops of WD40 on your fingertip, and then run your finger all along the edge of the gasket and it will slide right on.

Basically, take off the seat and plastic tank cover. On the right hand side, up near the steering damper, pull down the rubber skirting and there is the hose. Unplug it, and find a medium sized marble. I think I had a 1/2" or so marble that was a perfect fit. You could also use a ball bearing. Use something spherical, rather than a plug made of a cut piece of round bar stock. The marble is much easier to remove if you ever need to. A drop of oil and you can squeeze the marble out because of the round surface. A plug that is cylinder shaped is much harder to remove, trust me!

So insert a marble or ball bearing that barely fits and might require a drop of oil to get it in. That will make a perfect seal. Push it down in about 1 inch, and reattach the hose to the airbox and put the seat and tank cover back on.

It really is that simple. That blocks the vacuum hose and completely disables the PAIR system, without having to remove the whole gas tank and airbox, without removing the system itself and having to block off the hole in the airbox, etc... This will greatly reduce the burbling and crackling and occcasional backfire when you go from WOT to closed throttle and let the motor slow you down. It stops the system from injecting air into the exhaust system, which is where the noise comes from as spent gases burn in the exhaust. This stops that. It also makes dyno tuning faster and easier because you normally have to disable the PAIR system so that the dyno does not read that extra air and think your bike is running lean! So you do it once here in 15 minutes and then forget about it.

Just like the golf tee in the flapper vacuum hose, it disables the system but is completely reversible in minutes if you needed to return it to stock form.

Anyway, here is the little slide show with instructions. Feel free to share it or download the pics to keep them.

That looks pretty damn easy. Is this as effective as the other pair mod? I don't remember if the other pair mod removed it.

It's as effective, but cheaper, faster and a lot less work.

i removed one of the little index tabs for the gas tank cover/seal area and it speeds things up nicely and the seal still stays where it should,no more putting the shelter on with a feeler guage to clear the last seal tab.
