Pair Valve Removal

I did the removal today and I'm still getting a popping during decel.

We made our own plates out of aluminum.

Everything in the diagram above has been removed. Could I have a leak?

Running to rich?

I have a Yoshi slip on.

Any help is appreciated.

Also, instead of plugging the pair valve we made a 3rd plate to block it off leading into the air box.

youll still get a decel pop if you have a pipe, or pipe and filter. its running a tad lean.

get a tune and you will be good to go.

everything you did is correct, doing what you did doesnt fix a decel pop, it just removes the emissions, and lets for a more accurate tune.

and in some cases reduces surging, bucking at lower rpms

anyone who throws a pipe on there bike without jetting/tuning will have a decel pop

I was under the impression this mod completely fixed the popping. That seemed to be the consensus on the SV forums. Only reason I did this was to get a tune so I guess I'm good to go then.

Thanks for the info Hoblick.

no problem, sometimes it will reduce the popping, but generally it wont. all the pair valve does is take clean air from the airbox and pump it into the exhaust to hep burn up unused gases helps to pass emission standards.

and if the PAIR valve is still on when you dyno, it will make the air/fuel mix look leaner than it actually is, which really creates an inaccurate tune, since the monitoring of a/f is through a wide band 02 sensor placed in the end of the exhaust.
