I will donate my Dyno for the cause! Anyone on Long Island that has a ZX14 & wants to pull their secondaries out of the t.bodies PM me & I will set up a time when we can do some before & after runs. If you have a modded ZX10R PC IIIusb hooked up even better then we can dial out any fuel issues. Call me chicken if you want but my 14 is gonna keep the secondaries for now. This offer is not B.S. Free tuning for the owner of the 14 to be used!
Will post any results good or bad for all to see!

I think that is only a partial fix. I bet it does help and its free. But remember the computer also retards the timing until a certain rpm. If it helps some that would be ok. Someone has to go in the ecm. Then we'll really see a difference
Do we know the ECU excessively retards the timing until a certain rpm or is this just a theory?

Hi Guys, It has taken me forever to get on this site thanks to AOL. I was the one listed on the other site by a friend of my with a GXR1000. I removed these secondary flaps Saturday
and noticed that when the engine was cold the flaps opened up 3/4 throttle and stayed
there for approximately 30 to 45 seconds then closed completely. Raced the engine up
to 6K flap still closed completely at 7K they opened about 1/8 of the way. Removed the
flaps and the low end was at least double from stock. The front wheel wants to come
off the ground at 35K. The roll on is way better than before because I have to wait for
the flaps to open by that time the other guy is already gone. I did not notice any ill
effects from this mod except at about 1K the motor wants to chatter a little.
(Caution) If you do this mod do not over throttle the motor at low rpm's below 3K.
The ability to pass cars at 35K in 6th gear is way better than before. It if a lot more
fun to ride this bike in traffic now than before. I would have had to shift down 2 gears
to pass a car.

Well i for one want to try this mod ASAP !! But i'm going to wait till i see the fuel curve on the dyno ...I'm sure as stated it will make more power but i don't want to take the chance of running lean and burning a piston ....I don't feel that will be the case, if that where the case the motor would bog when the throttle was wacked to full open and it doesn't seem to do that as reported by the guys that have done the mod....Still i want to see the fuel curve first just in case...... If it where to be lean we could just add a P/C and add somemore fuel in the lower RPMs range.....Schnitz has a timing box that will advance the timing if the ECU is really retarding the timing in the first few gears ... Just some things to think about guys ... Smokin ....

Hey gt, let me know what part of Houston your in. Im not very far in Galveston. Maybe we can run the bikes side by side. Your with the mods to see the difference.

If it needs more advance, the tre will help too., cause thats where he removes the timing.- low rpm
My experience has shown that too much advance with high loads, lower revs will cause detonation and quite severe sometimes, leaner fuel curve down there because the secondaries are removed will make any advance timing even more critical.
So there you have it... if Ivan wants to sell the tre here's his chance to dyno the mod with it!
Strap that sucka back on the DJ again Stan!
BTW I am not selling TRE, I want my gear indicator and shift / launch lights as i will eventually try to wire a proper light up to the leads for the stock one in the tach!
Who needs a programable light, when the program is there... just wire up a proper light!
Schnitz box only advances above 5 or 6000 rpm, and only a couple of degree's, because it was designed to retard timing for NOS or blown/ turbo engines.
The PC3 with proper mapping and this mod will likely be the solution!
Just my 2cents

Thanks, I'm just willing to get to the bottom of the bottom-end problem & if I have the means to do it then so be it. We all benefit from it & make some more Hayabusa owners even more unhappy then they already are!
I started this thread titled (Does anybody have the low-rpm Fix yet?) the day I got the bike on 5/24. It would be nice to have actually had a hand in answering the question with a viable answer.

Anyone that pulls the throttle flaps will not be unhappy. I was riding out to my g/f's house tonight, and the pull in 6th while cruising at about 75 was incredible. I didn't think I was anywhere near the indicated 140 when I let off. I'm still getting used to the throttle response as it is more of an on/off switch than before, but that's something that would have been a lot easier to get used to if I rode the bike home like that! Cruising is very smooth, idle seems "slightly" different, but still better than my stock 10r/6r were.
Hats of to you RICH CRAFT 1!!!!
serius blk I live near the West side of Houston. How much do you weigh approx? I'm 215

hey , what if an ouside power source was wired to the secondary motor, with a switch, then we could use it depending on road conditions etc!
Instead of removing them all together.... I can think of lots of places where even the most seasoned rider could create self induced carnage mid corner!
Sure would be nice to really launch it at 4000 rpm instead of 6000.... clutch longevity and more consistant 60 foot times !?!

I would bet that the motor that drives the butterfly is a DC stepped/calibrated motor...making it tough to control by just a switch...

wire it in parallel?
switch on= valves open(have to figure out how many volts for WFO),
switch off =valves controlled by ECU?
If we used a relay so the ECU wiring circuit is open and will not back feed when the switch is on?
probably is a secondary position sensor? if wired up still might throw it into default mode
There has to be a way...
I hope!
Wish my shop manual would arrive all fucking ready!
I really want to do this but it sounds like its almost too much for the street, especially with a passenger.
Guess I will have to try it myself and make that decision for myself
Somone like Ivan, Dynojet, or Dale Walker should be all over this.
Hope Brock is listening!
I will call them tomorrow, as i need the shipping # for y pipe anyway!

Hey gt im 245 . The weight would be any issue if it were the 1/4 mile. If we're side by side in low rpm and both open throttle. That will definitly give us a good answer about the mod performance. Im in Houston alot. Just a chance to see against another 14.

Motor is only needed to open the valve and then MUST be shut down so as not to burn while trying to spin once the valve is WOT and "locked" open...then reversing it would close it...but once again. it can't remain on once the valved is closed...kinda like limit switches that would shut the motor once the full open/closed position is attained...ya, you're 100% right about the relay...are you in electronics by chance? Most guys would not have thought aboiut the relay requirement...
I guess you could just simply apply power for a few secs to get the valve where it needs to be and then do the same thing in reverse to get it back to ECU control. It's do-able buddy...it is! Once you get the shop manuals, we could post the wiring diagram for this patch...I'l help ya!

do the mod first... The on/off feeling is no worse than my stock 04 10r, just way diff than the stock 14.
You can always put them back in fairly easily if you don't feel comforatable with it.

hated working on daily driver POS, with owners who never could get it intheir heads to fix it fuckin right!
Got so sick of it I didn't even enjoy workin on my own rods, and bikes anymore.
I'll get in touch when the manual shows up.

I haven't looked at this yet but could it be a stepping motor ? It would rotate to any given position depending on the command from the ecu. Just a thought.
Also would it be possible to simply disconnect the motor from the shaft and put the secondary butterfly's in the open position, then lock them off ?
