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

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

Amazing content, thank you for explaining !

I did enjoy the video and I did learn something...thanks Brock!

Thanks for the video. I just bought a 05 gsxr 600 and I had to go through all the wiring because they had it all messed up from adding led lights through the years so I cut it all out and had to properly fix all the connections right and make it look OEM and put new spark plugs air filter and oil change, radiator flush just normal stuff you would do when buying a bike that was ran hard it's whole life. Man does it run good. I also ordered brand new fairings but they won't be here untill end of summer so imma have to run older ones that don't look to good untill they come..

This is a real knowledge.thank you

Great video. Very informative. Keep up the great work

That's the beauty of our combinations. It doesn't matter where you live - we do the work here and send the components to you, pre-mapped and ready to install.

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.

Great explanation of what to do with PAIRS. My old SV1000s pops like hell but I kind of like it.

Thank you!

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 ?

thank you

Thank you help me out a lot. I’m trying to figure out the wiring for my CBR 250r on a project. I’m putting the motor in a go kart. Could definitely use more help. Trying to find out what I need for the motor to run and run correctly.

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

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

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

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

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.

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.

still waiting for other episode. it looks like im watching game of thrones in a different way

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

Thanks

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

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 жыл бұрын

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

Hi Brock does the HTEV eliminator cause power loss? Honda CBR 900RR

@BrockDavidson

We have never measured any loss of power by removing them.

so if I only install slip on exhaust I don't need to block my pair valve?

yo... can you guys make some parts for the b1250? have most of my parts from Dale Walker, but stuff like wheels or master cylinders are hard to find.

pulse air injection reaction it provides extra air for the catalyst to heat up. modern bike use a speed density injection we used this in cars starting in late 80's Simple you cant put an rotatory air pump on it if u by pass it pull the catalyst off. Since you don't have a post cat O2 sensor you won't hurt a thing

on a bike with ram air it seems like some of the ram effect would be lost by air bleeding out through this port. Is that true or maybe not significant enough of an amount of pressure lost?

Hi Brock.. important question. So I had a PCV installed and had it dyno tuned. However since doing this, my bike stutters at low to mid range rpm when getting into the throttle hard. Feels dangerous because the bike accelerates then sounds like it farts and I get this massive hesitation like it feels as if the brakes are touched. It doesn’t happen at higher Rpms but only in the low range. To stop this from happening, I need to slowly but gradually get on the power. Not sure if the dyno tune was incorrect however I still have the pair valve running. Would disabling the pair valve cure this ?? My bike is a triumph Daytona 675, decatted stock exhaust, O2 sensor disabled but pair valve still running.

chuchu2301 - We have no experience with your bike, but I will try to point you. Copy your existing map to your desktop using the power commander control center software, then try a map or two from the Dynojet database (they are free) and see if your problems persist. If one works better than what you have - run it! All that matters is that you are happy with how the bike runs and that it is SAFE to ride. Some bikes will not allow you to simply unplug the O2 sensor- so when you say "disabled". do you mean in the flash? Is your bike throwing codes? If so, that can cause very undesirable performance. This will need to be addressed as well as the tune. Hope this helps - BD

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

Plates only reduce weight. Once the system is disconnected from the airbox it can be replaced with plates to reduce clutter and save a few ounces...
