Just fitted two brothers slip on duals to my 2012 zx14r and it backfires on deceleration.
Had the same issues with the two Hayabusas i owned.Solution was to put a marble in the hose ftrom the aircleaner to the pair valve to block it off.
Has anyone done something similar to the 14.
Idon`t want to stuff around removing pair and blocking it off.
Any advice appreciated

NO....you can't just block the 'pair valve' line.Try doing this....ON THE LEFT SIDE....remove that hose in the airbox.Block THAt airbox opening.Block the hose as well...with a wood dowel or rubber stopper...something that won't deteriorate.That should take care of the decel pop....along with a PC mapped for your aftermarket pipes.Traditionally...you would block the right side hose and all....not with the 2012 14R....the right side leave alone.

Thanks for that , I`ll try that on the weekend.
It is a similar procedure as the Hayabusa,but the busa has only one hose to block off.

The gen1 ZX14 also has 1 hose. Maybe these will help a little although from what Grn is saying, sounds like the 14r has a little different setup.

Decel popping is caused by an overly lean mixture and usually presents it's self after putting after market pipes on your bike. Blocking the KLEEN Air system (pair valve) is one way to nullify the pop. As was previously stated it can be done by blocking the hose from the air box or by completely removing the KLEEN Air system and blocking off all components. The KLEEN Air system injects air from the airbox into the the exhaust for emissions purposes, so obviously when you put a higher flowing pipe on it causes the mixture to lean out too much.

If you've blocked off the KLEEN Air system and you still have popping you'll have to add fuel in the 0% tps range in the map on your fuel controller. This will add fuel when you're decelerating and should get rid of the pop. I wouldn't recommend adding a whole lot of fuel right off the bat, because it will slightly decrease your fuel efficiency. Instead start by adding 5% fuel in the RPM ranges it pops, and then continue to increase by 5% until it goes away.

I should also add that you can get popping from your exhaust if your mixture is very rich, but this isn't the norm and is usually more prevalent on race bikes with short exhaust systems. If you've ever watched Tommy Hayden come into a corner on his YES Yamaha R6 then you've seen his pipe spitting flames; that's what I'm talking about here.

Z with an after market pipe you lose the cats in the mufflers,Kleen air helps to burn off on burnt gas,that is not a lean senario,with aftermarket pipes you will hear the burn off,If you richen it up with PC not only due you get popping but also flames.I agree with blocking off the pair valve

Correct with a stock exhaust the KLEEN Air system helps burn off excess fuel, but when you go to a full system the AFR levels lean out, b/c you no longer have a cat restricting the air flow, then add on top of that more air being injected by the KLEEN Air system and you have a very lean condition which causes it to pop. I can watch that happen on my AFR gauge when I'm on the dyno. And when I'm building maps for our Z-Fi units, it's always by adding fuel that I successfully get rid of the decel popping; taking more fuel away only makes it worse.

Where I am in Ontario I'm about 500 to 600 ft above sea level,on my 07 with a brock S-meg and brock map I was getting popping on decel.I went down to north Georgia in a national park not only was I popping more but also shooting flames,to the extent of being escorted out of the park for being a fire hazard.Cant recall the altitude but it had to be 3000-4000 ft above sea level

I just removed my hoses and plugged the right side hole in the frame/airbox.I put in Ivans block off plates.Wasn't really necasarry.I could of capped off both covers but I allready had the kit.I tell you with my full exhaust I can't get it to pop.Kit cost me $54 at 58cycle.com.Now I'm trying to get a decent speedohealer.I just couldn't get mine to work.At 70 its really 76.About 9 percent off.I'd get the Muzzy Bonneville kit but I'm scared about cutting a ECU wire.
Craig

I'm guessing you have a V4 speedohealer?It will work...just need to set it correctly...that's all.The online settings work...they're very close....you just need to dial it in a bit more either way to get it dead on.Takes some driving and stopping and driving and stopping to get er lined in...but it will.

Ivan's TRE006A is the only 100% fix for decell popping that I have ever found.

I have Tried Everything listed above plus some,,,,, Over and Over I tried because others said they found a way. One summer I must have made over 100 decell pop maps lol. Lots helped but nothing was 100%. Just sayin if you want 100% fix, spend 60 bucks and be done with it.

Simple Mod, but no gear display sucks. No fuel cut in the corners = Smooth

Ivan has solved the issue in the ECU on the new 14R,,,, All good.

No more Explosions in your new pipes,,, All Good. Promise. If you don't like un plug ?

TRE-006A - $60.00
2006 & up ZX-14
Requires sub-throttle plate removal & special mapping.
Gets rid of fuel shut-off on decell -
This will allow smooth on/off throttle transitions and will get rid of the annoying pop when the throttle is reapplied.
Gets rid of part throttle timing retarder in lower gears.
Our maps are only available with a minimum purchase of $200.00 or more.

Hey Romans it says it requires a special map for use with the TRE006A do you get it with the sale or if not where do you get the proper map.

Mine won't pop no matter what I do.Block off plates and plugged air box.No tre no maps no fuss no muss.Take it up to 8 grand in first and let go of the throttle.If that won't make it pop nothing will.

Audio I'm glad yours does not back fire at 35-3700 RPM on the decell. But, the mods you speak of was Not a 100% fix on Both my Gen1 or Gen2 ZX-14's with full pipes. And yes I had the exact same mods on both. I have and ran all Brocks Maps and still the boom was there.

Take it up to 8 grand in first and let go of the throttle.If that won't make it pop nothing will.

Made no diff on my bikes if you went to 8000 or not. Boom on decell at 35-3700rpm = boom. Some times worse than others. Sound about wright ?

I track AFR fuel tables from stock ECU settings and can see at what RPM kawi turned off fuel for emissions control. I can also see when in the RPM window When kawi turns fuel back on. No problem to understand why this explosion happens.

Block off plates do nothing to change fuel cut from stock ECU settings,,, how could they ? Block off Plates Help keep fresh air out and thats all. Fuel still gets turned off and then back on and when it comes back on = Boom. ECU is prg that way.

Run straight pipe for a while engine gurgle tells all. Good muffler will keep a little quiet but nothing has changed.

Guys take it for what it's worth. I hope this helps. Cheers

Old fool the TRE006A is only to be used with your secondary Throttle Plates Removed. Most guys have them out in the Gen one bikes and allot with Gen2. Not sure which bike you have or if your flies are out ?

I have forgotten what resistance i measured the different gears gave when I modded my old 06 non turbo model.
Can anyone tell me which gear or N that the display is left in when the tre is fitted please?
Grin

Romans , I have the secondary flies out and have the pair blocked it is a 06 with full muzzy exhaust and pc3. I cut the popping down some with the pair block and modified map but I still have it and would like to cut it out altogether.
I read what you said about the TRE006A went to the site and read it needed a special map but says nothing about where to get the map. So what can you tell me about this. Thank you for any information.

Sounds Sweet. That set up of yours won many Dyno Pipe wars when the ZX-14 was introduced to the world in 06. I had the 07 model and getting rid of that backfire became a obsession of mine So I can feel your pain.

When the flies were removed a lean condition was created at 35 to 4000rpm if memory serves(above 14.2). The problem is, this is the area where you spend allot of time on highway cruzzzzzing. 6hr trip running with lean AFR probably not good.

SSB had a test bike run for two years with no mapping at all and all was ok, but for my nickel richen it up a bit your self or,,,

Ivan, has spent his time to make maps for your exact set up,,, Call him C if he will help you out. Brock also has maps made for this set up.

Romans I have read your article several times over the days and studied Ivan's site and just tonight I saw this line (Our maps are only available with a minimum purchase of $200.00 or more). Duuu Thank you for your help.

I know this is an old thread, but here is one block off

If you read Brocks Description

(PAIR) to help prevent ‘deceleration pop’

Help Prevent,,,, "Help" being the key word. It does help, but is not a 100% cure or at least not any of my bikes with decell maps also added. I could not solve this way.

What do the block off plates do that brock's simple plug doesn't do?

What do the block off plates do that brock's simple plug doesn't do?

Block off plates allow you to remove all the plumbing of the pair system. Once removed you have a bit more free space for your hands. You still need the plug.

To answer your question,,,,, not much lol Early on we just stuffed a marble in hoses,,,, Freeeee. The Marble Trick ?

I've grown to like the popping.I'll probably remove the clean air first time I have to remove valve cover,makes service much easier

I'm running a M4 full exhaust and even after plugging up the hose located under the left side of the airbox it still pops, not as bad as before the plug but still noticeable. I added fuel to the 0% column and it decreased some more, but the popping is still present. I'm curious if anyone who has dynoed their bike or has access to a tuning kit such as Woolich Auto Tune, has eliminated the popping after tuning the IAP fuel map? With the PC5 it only adjust fuel for TPS and not IAP, which IAP dictates fueling in the lower RPM range based on absolute pressure but transitions into the TPS portion of the fuel map. If fuel is added to this section of the ECU's fuel map, maybe just maybe the deceleration popping can be completely cured...especially with full exhaust systems with short mufflers such as voodoo and M4.

Thoughts?
