Tech Talk: PAIR Valve Systems Explained - Brock talks PAIR valve systems. What is it? What does it do and what does it mean to you and your motorcycle? We are addressing it with our 2017 GSX-R1000 project, so Brock decided to stop and allow you to explore this sometimes ‘mysterious’ system with him as he works his way from ‘Stock to Brock’!
Introduction - What is a PAIR valve? How does it work? Let’s find out!
1:00 PAIR (Pulsed Secondary AiR Injection System… I didn’t make this up)
2:30 Vacuum test using a simple piece of paper
3:10 Where did my vacuum go?!
4:04 Demonstration of PAIR openings in exhaust port using Busa cylinder head
4:50 “If I block my PAIR, will I pick up MORE POWER?!” (Uhhh… no, sorry)
5:50 Why would I want to block my PAIR?
6:23 Brock’s PAIR valve cap. The KISS principle (Keep It Simple, Stupid) at its finest!
7:00 POW! CRACK! BAM! KA-BOOM! Maybe I DON’T want to block my PAIR
8:30 The difference between a BLOCKED and DISABLED PAIR in ECU flash technology.
9:15 What happens if I tune my bike without the PAIR valve blocked?

@michaelovitch 7 лет назад

Don't be afraid to be "technical" it's interesting,not boring at all. This is why i watch your channel,you explain pretty well. There is a similar system on cars,it's just an air injection pump ,pumping air to the exhaust manifold to reduce emission during the closed loop period.

@BrockDavidson 7 лет назад

michaelovitch those pumps are mechanically driven, help seal rings and prevent pumping losses. They also run for seconds at a time. Ever try one on a street bike? The oil pressure light glows in seconds?! Is it starvation, our just tricking the switch?...how many engines are YOU willing to kill to find out?

@BrockDavidson 7 лет назад

michaelovitch ill get technical in my replies ;)

@michaelovitch 7 лет назад

I don't understand what the oil pressure light have to do. I miss something ? I just said there is a similar system on cars,except it's an air pump,mostly electric,it's not a venturi system like here.

@topprotips5250 4 года назад

Brock Davidson hey Brock love your videos man . So I have a 2014 gsxr750 and I’m blocking off my pair valve , there are 3 hoses I’m blocking . 2 of them come from the valve itself and the other hose is connected into the pair valve solenoid . My question is do I block the hoses themselves or the ports coming from the valves and the other one going into the solenoid

Thanks for taking the time to make this video Brock. It makes total sense now about what the PAIR valve does and how it affects the motorcycle. Great comment at the end about how the valve will give a false 02 reading.

@alexsharkey6562 2 года назад

Absolutely. Could be why some people don’t get the performance out of their aftermarket exhaust too. If they don’t take into account the false o2 reading with out the block off.

@mantasjaskevicius1385 4 года назад

@tsugha 4 года назад

Brocks can we say, blocking pair port will prevent vacuum on port so inlet air pressure on airbox will be higher, which is a good thing if you want to get hp by tuning.

@alex-thangnguyen2746 6 лет назад

Hey Brock, I really enjoy your videos and how you take the scary out of all the new high tech wizardry in engines now. Can I pick your mind regarding the PAIR system. In the old days, you could put your hand over the exhaust and determine if your bike is running lean or rich. I kept testing my bike's carburetor and assumed it was running decent; however, my mileage dropped and I noticed this. My fuel range was so off, I could not figure out why I did not diagnose or notice a rich powerband. My question to you is, do you know of any other method other than a diagnostic tool that can quickly and accurately tell a tuner if the carburetors are set in the sweet spot through the powerband? I did notice extra heat through the pipes. Another source of this heat is the headers; such as rust or what happened to me, the previous owner did not bother to use any header cones, thus, producing a leak and a drop in engine performance overall. The natural thing when you have this power drop is to turn up your fuel-air mix exacerbating the situation even more. So my question is, do you know of any method when you put something over the exhaust and do a sniff test for running rich? The scope of your knowledge and the process you use to simplify the understanding of the topic speak beyond the science of it.

@LightningMAS 7 лет назад

Any updates yet??? im excited, just ordered a sprint filter from ya for my bike.

@fidelcatsro6948 6 лет назад

i read somewhere when you block PAIR from the intake box, its frees up more air pressure in the airbox for the engine to use...perhaps only during the low and mid range because as you showed it doesnt do anything in high rpm..

@BrockDavidson 6 лет назад

Don't believe everything you read on the Internet ;)

@kurtisprodrive9277 5 лет назад

If you wanted the bangs and pops but not as much could you use blank plug but drill tiny hole in so still draws some air in would that work thank you

@Foozefighter 3 года назад

on my carbed SV i disabled the PAIR system by plugging it, because test showed 2 heads one with disabled and one with enabled PAIR, enabled PAIR was burning the valves and valve seats away earlier than disabled one

@jasonpowell4847 7 лет назад

On tuning with a catalytic do most tuner tune leaner or richer. If possible would it be better to have a standalone wide band o2 before the cat.

@oldfartuk 3 года назад

i love the popping .. keep mine on /..

@st3rg 6 лет назад

did i get it right measuring exhaust gas emission on a stock bike will result ok but on a bike with blocked pair with stock parts measurement will show rich mixture ? if thats the case what will the result be on a blocked pair valve with an aftermarket air filter and exhaust ?

@moreclips805 Год назад

Hey Brock, Thanks for putting this together. Very informative. I bought a bike that has a full exhaust, however the pair value (electrical wire) was simply unplugged. No cap on the vacuum line itself. Bikes developed a surging issue, changed rectifier ignition coils and spark plugs. Do you think the pair valve can be causing a surging issue at idle? When I drained the oil I smelt fuel. Maybe not enough air to combust the fuel causing it to leak down into my crankcase?

@BrockDavidson Год назад

No. The pair valve has zero to do with how the bike runs. It simply injects air into the exhaust pipe, after the combustion process, to help the cat work correctly. The chances of bad OEM components causing the problem are near zero. Sounds like you need a proper flash and tune. Get with Chris Moore at mooremafia.

@moreclips805 Год назад

@Brock Davidson thanks for the quick response Brock. Appreciate the help!

@irshadparak3285 6 лет назад

Hi Brock, I love the vid. I have a 2005 Gsxr 1000 with a bmc filter and a yoshi slip on. My bike is going in for an ecu flash and dyno tune in Jan. I love popping sound on decel but obviously I'd choose performance over it lol. Should I order block off plates and install them before doing the flash and tune ?

@BrockDavidson 6 лет назад

@Irsha -There is no need to for you to disconnect the PAIR if you like the popping sound. Your dyno operator will have the ability to temporarily block the PAIR for tuning (plastic cap, hemostats or even a simple piece of tape) and then remove the temporary block after the tune.

@irshadparak3285 6 лет назад

Brock Davidson thanks Brock, really appreciate it

@jscottc6675 5 лет назад

When is the pair valve commanded closed by the ecu? 2016 zx14r here. Keen air still unblocked. The '16's O2 sensor is installed in an aftermarket pipe. Ecu re flashed and dyno tuned. Only slight pop, just on decell. Bike responds well . Fuel consumption remains or is better than stock exhaust during light throttle cruising. J

@xzistpo 6 лет назад

Thanks for this! Can you tell me if the pair valves are the same as the SAS or secondary air system ?

@BrockDavidson 6 лет назад

Yes. SAS was the term coined in 1966. Additional have been added since, but the basic principle is the same and in some cases - identical.

@fattymcgee123 7 лет назад

@dok222 4 года назад

hi Brock, my Gsxr pair valve closes on decel and opens when im in throttle. is it normal or its somehow working opposite?

@bchant19 6 лет назад

so for tuning purposes, you need to block the pair valve so you don't make the bike run too rich but when the tune is done you can unblock the pair valve again to get the sweet decell pops and not lose any power?

@dariodipaola8445 6 лет назад

Yes. But, if you want to run an auto-tune or something like that, you will want to use block-off plates. Your autotune sensor will identify false A/F ratios if your AIS has a part in the output data. You want to eliminate that noise from reaching the sensor so when you open up your auto-tune tables and apply adjustments, they will be true values. If your auto-tune is reading data off the AIS system, your adjustments values will be fake & likely reduce power for fuel economy... who needs that! xD

@code_red7744 3 года назад

Can anyone help me out? I unblocked my pair valve after a tune because I kinda like the popping (yeah I’m weird) but I’ve noticed it’s jerky at lower rpm... can this cause the jerk at low throttle being unblocked after being tuned with it blocked?

@BrockDavidson 3 года назад

You are not alone - many of our customers LOVE the pop! Unblocking of the PAIR has little to no affect on your tune as everything it does is on the exhaust side of your engine. When you say "after a tune" I suspect that the jerkyness was caused by the tune, especially if the PAIR was not blocked when the tune was performed.

@icemanlol119 2 года назад

Hi My Suzuki m109r has high flow air intakes and aftermarket straight pipe exhaust , I took it to a tuner to flash the ECU he tried 2 times getting rid of the backfire obviously he doesn’t know anything, now I know and I’m going to block the valve myself. Thanks

@BrockDavidson 2 года назад

@iceman Lol - not to cut your tuner any slack...but straight pipes have a tendency to backfire more. That said, if the PAIR isn't properly blocked, the popping will be even more severe.

@jimjames4884 15 дней назад

G'day Brock. Great video thank you.I have a 2023 GSXS750 that has a slip on muffler but stock headers with the Cat. It has just been tuned. It was tuned with the pair blocked of course. I have removed the plug in the Pair line and it idles a bit smoother and I am getting bangs and pops on decel. The decel fuel cut is also switched off. Should it still do this with the Cat not removed? Will it damage anything? Thanks.

@BrockDavidson 15 дней назад

No engine damage, but the popping could damage your slip-on. Hope this helps.
