everyone said get the 08 cause there was a huge upgrade

Now that's just not True. With equal mods ????? Naaa

chatvmax, when I bought my 2007 I was crushed on how little bottom end I had. First two days I was thinking of selling.

1. Pull your secondary throttle plates{flies} Free Mod

2. Bike is geared to tall 4 some of us. Play here. Both will make you Love her. The rest is up to you. cheers.

I have an 07 too and yeah, its flat on the bottom.
I was thinking about a Guhl reflash as Ivan doesn't have his own flash for the early bikes.
I don't want a Power Commander as I've had a couple failures.
Suggestions for us 07 guys?

I have an '06 and it is a monster on low end. This lowend stuff was all worked out with these bikes years ago, I would call Ivan at Ivan's Performance in Rockland County NY and buy his entire package for your '06/'07. His prices are dirt cheap and he is the best street tuner in the country IMHO and I've used his services for both my 14 and ZX-10R.

On the '07/'07 the catlayst is in the exhaust end cans so all you need is a good set of slipons to let the engine breathe better and free up some HP and torque. I used Yoshimuras but there's other good ones out there. A full system will add about +5 HP at peak over a set of slips but you lose a lot of the low and midrange grunt. For street, slips are the way to go on this bike, ask Ivan.

You'll need a PowerCommander PC3 and Ivan's mapping alonq with his TRE006A. The TRE is the key to making the whole thing smooth and there is absolutely zero backfire on throttle rolloff with the TRE on there.

Remove secondary throttles (flies), takes about 1 to 1 1/2 hours to remove flies, hook up the PC3 and download the mapping.

Bike will be absolutely transformed!

Flies Flies Flies,,,,, Remove ASAP.

Yep, If you look at early Dyno sheets the 06 07 made more power than the 08-11 which has the smaller injectors. I have had all 3 gens so I can tell you for sure,,, follow Kruz input and this bike will B all you can handle. Wheelie at will.

I was thinking about a Guhl reflash as Ivan doesn't have his own flash for the early bikes.

2006-2011 models HP fell off early up top so no need to raise rev limit. That being said no need for reflash.

I am a firm believer that the secondary throttle plates on the 2006 were Dangerous. Pull them and you will never regret it.

Drop one tooth up front. (It was too buzzy, so I added a 45T to the rear with a stock counter sprocket)---Perfection for me. F**ING MONSTER...completely different animal.

...and Hang on.

Use Guhl, Ivan, or do it yourself...regardless of how you do it, remove those flies & adjust the gearing like Romans said....I fell in Love with the bike after I made these mods.

I mentioned Guhl only because Ivan doesn't have a flash for the 06-07 and I don't want a Power Commander as I've seen them fail. This is my road bike and its not uncommon to be 500 miles away from home.

BTW, I'm an old friend/customer of Ivan's.
I have great respect for his abilities.

There's a real good flash for the 2012 retaining the flies...
That's the only reason I asked about the Guhl flash for the 07.

ok<< i can build motors ssoo i am fairley handy,, can someone tell me<<
secondary throttle plates..??? is there a writeup on this i can follow,,
If i remove them do i have to do anything with the fuel system,,,??

also can you tell me exactly how many tooth rear sproket ( remember i am looking for my low end,, )
or does a sproket change sound like s BIG jump for this issue....?

i feel i can do this work and i ALSO wanted to install a set of block off plates JUST because,,
does this sound like a good start...??

Thank you so much for all the advice,,
PS: I have a set of slip ons on there now,, that is the ONLY thing i had don to this bike to date..

Please give that man a cold one
I had too many closed calls... Cold bike, you're going into a corner, you try to get back on the gas smoothly and you get nothing, 1 second later the bike wanna tear your arm. No thanks.
Flysectomy is the best modification you can do on a 1st generation. I would go with a full system (Brock's CT-Duals or Akrapovic) get a good map and you'll gain everywhere. Let the mods begin

ok so is the line of thought that i MUST do other things to the bike when i remove the secondary fly plates,,,??
like pc and maps and such...??

Super Street Bike Mag had Test bike run for two years with only TRE and flies removed.

"Super Street Bike Mag had Test bike run for two years with only TRE and flies removed."

ok ssso im reading that as you cannot JUST remove the flys,, u HAVE to do some other work<< like a PC III or TRE,,...???

ps: is there a writeup on HOW? where to get a writeup on removing the flys
'???

Rook,,,where R you ? Thinking Yes ?

Lift fuel tank, remove two coverplates to expose the throttle bodies, remove the secondary throttle phillips head screws, two screws per throttle plate. Use a long #2 phillips with a sharp bit. I used a 300 watt Weller soldering gun to heat each screw and soften the thread locking compound. I also tapped the screwdriver with a hammer to set the tip.
You do not want to strip these screws! After removing the screws, remove all four secondary throttle plates and throw them in the trash! Now go ride bike amd enjoy immense low end throttle response. TRE, PC3 and remap only required if you want perfection, bike runs fine without them, lots of guys pulled the secondaries and have been running stock ECU fueling for six years now with no problems.

Yes. After removing the flies you should get a PC to smooth the power curve. I know! You gotta a spend on that bike to enjoy it the way is what meant to. That's why slip ons aren't worth it in my opinion. If you are going to get a PC may as as well get a full system!

When you get the tank lifted, you'll see the throttle body cover plates in the top of the airbox, if I remember, two screws per cover plate. The secondaries (flies) are the top set of throttle plates, the main throttle plates are down below, you don't mess with them. Use a magnet, do not drop a screw into your intake!
Whole job, one beer, maybe 30 to 40 minutes.

Get a PC3 and Ivan's flies out map, well worth it, this is the best running bike I own, throttle response is near perfect from idle to redline, very smooth and linear but pulls your arms off from as low as 2500.

Rook,,,where R you ? Thinking Yes ?

Sorry pulled the flies on my 08 wayyyyyy before I thought about doing a how-to.

I think I might have enough pics to construct a half ass decent fly pull HowTo.

The secondary flies are controlled by the computer and the computer is programmed to restrict below 6K rpm. The primary flies below the secondaries are controlled by the throttle grip only. Problem: secondaries are upstream of primaries so the only air you get is what the computer gives you. Remove secondaries = you control throttle as you wish. Open up bike's full low end potential (or at least you have gone a long way toward doing that).

Start with the fuel tank removal. FUEL TANK REMOVAL

After that, You will see this:

Remove the bulkhead doors. You will see this:
FLIES IN

Get yourself a BRAND NEW HIGH QUALITY #2 phillips screwdriver, 9 inch shaft (TWSS! ). Heat up the screwdriver with a torch and set the bit into the slots on a screw. let it sit 60 seconds to melt the threadlocking agent. Press down firmly and twist carefully DO NOT STRIP THE SCREW SLOTS>>>>do anything but don't strip the screw....if it does not come out with a little twist, stop and think how to get ot out the right way....heat it up more. DO NOT USE BRUTE FORCE OR IT WILL STRIP.

Some people report having much better luck with a soldering pen to heat the screws.

You will need a magnet tool or something to remove the screws without dropping them down the intakes.

after you have removed two screws that hold the plate to the actuator shaft the plate can be taken out. Move on to the next one. There are 4 plates in all.

FLIES OUT

If you go ahead with this, we are here to give assitance/moral support.

heheh, this will be like the old days. I remember the flyectomy threads quite well. Good days!

Whole job, one beer, maybe 30 to 40 minutes.

"Famous last words."

maybe 30-40 once you actually get to the flies.....then put it all back together w/out secondaries.

I didn't need to tap the screwdriver at all. Get a high quality screwdriver and it will fit well. If you DO tap, don't tap too hard and bend the actuator shaft. That thing still has to turn after the plates are removed.

Your bike being an 06, I'm positive those little screws won't come out without a fight. It took me two hours!!!!
The first 3 plates came out without any problem but that last one... I had to tap gently with a mallet but still managed to strip the last screw. It was "lingerie night" and the wify was falling asleep so... the drill came out. I just had to put a rag under, drill the head out and use a vacuum before removing the rag. Then I went for a quick ride, what a difference!!! Last time I checked that screw was still there

As I recall, we did flies out, PC3 install, TRE006A install, uploaded Ivans map and set the throttle points with Ivan assistance. My secondary plate screws came out like buttah but some of the guys reported stripping a couple of them out. I think the decision to buy a brand new, sharp, #2 screwstick made all the difference.

Hardest part of the whole job was the getting the ECU main harness connector disconnected so I could install the PC3, that sucker was stuck!

Last time I checked that screw was still there

That was the concern, if you drilled the head off that little hummer, would the threaded portion of the screw loosen up later and drop into the intake..... instantly cratering your motor. Never heard of it happening to anyone but knowing what a worry wart I am, it was one less thing to be concerned about.

@Chatvmax: Sorry we are digressing. Here is all the info you'll need as far as low end issues and TRE. Don't buy into the Ivan-Brock's beef, they both make great products. Ivan seems to be a little more street oriented while Brock is a drag racer.
ZX-14 Low end
Note that on the 1st generation (06-07) flies open up at 7000 rpm, it opens sooner on 08- but my conclusion from that article is that if you have two 14 that produce the same power no secondary flies paired with the right map will always yield more grunt than a set up where flies open early. Furthermore, I like my gear indicator.
