Top Speed Restriction
I can say that the Nikko-GPack does remove the speed limiter....I had my first chance to test my 05 ZX12 on a 2.0 mile straight with the help of a friendly law enforcement officer and a radar....It registered 196 mph....It was wierd because once I hit 6th gear and the speedometer got in between 180-190 the needle started to spin and act crazy, but my tach needle kept pulling, I prob. could have gotten somemore mph but I let off at 12,500 so as not to take a chance and float valves...lol I have some mods to the bike besides the G-Pack, full Akro exhaust, PCIII USB, BMC filters, KLEEN system deleted with Muzzy block offs, crankcase vented to atmosphere......oh yeah, I had just changed the oil also..lol

If you're running stock gearing, your tach is reading fast. Unless the computer has been modded, the bike would never see 12,500, as most rev limiters cut in by 12,000.

the stock tach is off compared to what the bike really does on every 12 i believe. my data logger told me i was short shifting when i thought i wasnt, and showed me where i hit the rev limiter (opps)

Congrats, but something doesn't sound right. The stock tach shows a redline of 11,500 and usualy indicates the rev limiter at about 12,200. Those numbers are about 600 rpm high, meaning 12,200 on the rev limiter indicated is about 11,600 actual.
With an ecu that has extended revs seeing 12,500 should be no problem but a stocker reading 300 rpm higher than normal...? Possible I suppose but not very probable. Any chance your eyes were playing tricks on you (entirely possible at those speeds, especially if that was your first time running that fast)?
In any case, glad to see it worked!

I'm running 17 tooth front and stock rear gearing....I never hit the rev limiter in 6th gear...I called back to the UK and this is what they told me about the Nikko-GPack as it pertains to the 04-05 ZX12R....In 6th gear it eliminates the speed restriction by bypassing the rpm limiter...the speed restrictor is in the instrument cluster, not the ecu like so many people believe, your instrument cluster sends the tach signal to your ecu letting it know when maximum rpm is achieved in 6th gear, the GPack bypass's this signal somehow....also they said it operates simultaneously on ignition advance, and the movement of the secondary flapper valves....and no this wasn't my first high speed pass, my modded 05 busa would easily do mid 190's....but regardless of what my eyes told me they saw, I can't argue with a calibrated radar system from a police vehicle....

i hate to sound this way but the radar guns here need to be calibrated often. i bet high speed they are off. but that is great that the gpac works and u got a fast bike.
i am going to the donalson soon with my garmin zumo. stock limit 2.75 final (16/44)
people say i should top out 187ish at 11,700. well i now have till 12000 so i will see later.

something sounds wrong with that one. Tach on my 05 wont go to 12500 with the gpack. Not even at 187 at maxton.

i am fairly sure they gave him a line of bs on how the limiter gets its signel. but no for real data except the 16bit busa denso ecu does the limiting like the zx12 denso and 60% of the softwase is the same. if he would say what he said the tach signel works like on a busa that would be a lie on behalf of the gpack people. i am sute the crank signel pickup goes to the ecu first in the wire diagram and not the dash first.

jumping in here rather than starting a new thread, looking to get my B1 de-restricted, looking for the home made kit article with instructions on the build and component list, I think it was by ridgeracer but I cant find it.. Got my first top speed event coming up in may and there is loads of stuff i need to get yet so if i can save a bit on this for the first event it will help a great deal.

I havent been online in a while, but does ridgeracer now do the 32 bit ecu's? The 2005 model has the 32 bit, more like a zx-14. What mods are the zx-14 guys using to derestrict their bikes for LSR? Im sure someone here knows. Only thing I have heard of possibly working is unplugging speedo each run. Now I have yet to try this on a dyno, but if someone has access, maybe try. Unplug speedo and bike will run, then while running F.I. lights come on but reset by turning key off between runs. If crank sensor runs straight to ecu, this wouldnt work. i believe Gpack plugs into harness here. I have been to Maxton several times on my 05 with many mods and a gpack, even with 40+ shot of nitrous, nothing over 187.3. Not enough evidence for me to believe in the gpack.
i have heard of installing a speedo healer and turning it way down, not sure if this works, if crank sensor is the answer, this wouldnt make a difference anyhow. Im open to suggestions, just no dyno local to me.

ridge racer has not goten a 32bit zx12 ecu yet. and the zx14 has not been cracked by anyone public as of yet.the 32bit zx12 ecu will probally be like the 32 denso busa. there is not as much of a need for us guys on the "less popular" 12 i guess.

Ok so I posted on the zx-14 board to see what input those guys had. I know some have been out in the LSR scene. They said they use the speedo healer to fool the ecu. Best answer Ive heard. i may just have to get one. Seems if this is true though, unplugging the speedo may just do the same. Hope this helps someone.

the speedohealer method works on the 12r as well.

I hate to differ here about the top speed restriction on the 04-05 ZX12... Jailbird you say that running your 05 ZX12 with the Nikko G-Pack and a 40 shot of NOS you could only manage 187 mph...That was from a standing start through 1 mile at maxton right...I had almost 2 miles of straight road to get up to speed.... what other mods do you have....the 32 bit ECU in the ZX12R is nothing like a busa...it's a Denso unit and that's about as close as they come...if they were pretty much the same, don't you think they would have come out with a TRE for it by now.... also Jailbird something else doesn't seem right to me, you question as to where to even plug the G-Pack in at...I thought you had one...I can tell you if you really want to know...and contrary to popular belief the speed restriction on the 04-05 ZX12 is implemented by a signal from the Intrument cluster to the ECU... it works like this....the gear position indicator sends a signal to ECU letting it know it's in 6th gear...the instrument cluster recieves a signal from the speed sensor which reads off the crankshaft, but is NOT the crank sensor....this sensor feeds through the instrument cluster sending a signal to the ECU when max speed is achieved in 6th gear to exhibit 186 mph limit...it recieves this signal from the instrument cluster via the speed sensor...the ECU calculates this signal which is measured in Hz and sends an output signal to the instrument cluster also known as the tach pulse ...the speed sensor signal is also used by the ECU to operate the secondary butterfly's...the ECU does monitor crank position and cam at all times but only for igniton and fuel timing...don't ask me why Kawasaki did it like that, but that's how it works...obviously it works to good because nobody in the aftermarket world wants to touch it except Nikko and the speedo healer will work also...the new speedo healers have a switch so you can just switch between normal riding and top speed runs....

I know where it plugs in on the bike. Down by the gear shift, I dont know if thats the crank sensor. In the runs at maxton, maybe 10 runs, the bike hit the limiter in 6th bofore the traps. Been racing there a few times bike always went 187.xxx never better. Id rather try the speedo healer and see next time. I personally didnt even see the rev extender that both the gpack claims, as well as the dynojet ignition module. Neither of them let it go over 187 on my 2005. Its got muzzy exhaust, fuel and ignition commander, BMC's, 40 shot dry, lowered front and rear, lightened all around, etc. Nothing special but bolt ons and tuning. Just from my time at the track, Noticed zero difference with the gpack in rev's and top speed. problem is only cops radaring me arent doing it for fun, and would be writing tickets.
Im going to have to get one of those new speedo healers and try it at Maxton and see what it does.

In fact if any wants a gpack straight from france id sell it to you for the price of a speedo healer. I think it was a bit more expensive but hell id rather try something new.

Yeah, it plugs directly inline with your speed sensor on the left hand side of the bike down near the gear shifter...did you get the G-Pack Over 3 module, or just the regular G-Pack....the Over 3 module is the only one that also eliminates the top speed restriction...yeah try the new speedo healer, my friend just bought one for his 04 ZX12 and like I said it has a switch to change between regular riding and top speed runs, it's plug and play install also, not like the old speedo healers...hopefully I can get to Maxton this year or next, only problem is I hear they won't let you run unless you have a one piece suit, no zip together jacket and pants allowed...

I think you can run 2 piece leathers. im pretty sure i have seen it done, but Im sure it has to have metal attatchment zippers. Most of the guys I know who have raced a lot refuse to wear two piece because they come apart often if you hit the ground. I have 2 one pieces, one leather, one kevlar. I hate the way they both fit. My two piece is way more comfortable but has plastic attatchements so cant use it at Maxton. So I always end up in the one piece leather. My GPack is the over 3 module. i couldnt find any here in the US so I had to get it straight from Nikko in France. Had it for a couple years. Im ready to try something new this fall at maxton. I saw some of the new speedo healers on EBay for 109, couldnt tell if it fit the 2005 though. Id have to contact them and see. Tech inspection is kind of a pain there unless you get there friday in the afternoon and get your log books signed early. Sat. morning is a madhouse. I got my 12 set up for Maxton once with all the safety wires, etc and I just leave it that way. Easier to keep it that way than set it up over and over.

The only thing I have to do is safety wire every thing...I already have a Scotts steering damper...I heard you have to run an aftermarket damper to run at Maxton, besides the ZX12 needed it anyway....

Yeas you got to have one. I got the scotts also, works great. One of my fav mods I did to the bike. Get ready for tech inspection isnt too bad. Just takes some time and some drillbits.

Here is my 04 12r, it has a modified ECU From Dave "O" without the gpack you see the speed drops off at 186 the restrictor is working... with the gpack it kept on pulling until the duno operator backed off past 195mph.

Now thats results I can see working! Good work. No dyno within miles of here to try that. Why did he stop at 195? Ring it out and see what it will do. And what gearing was the bike running then?
