2000 zx12r speed restriction or not?

Iv'e never been able to figure out if the 00 ZX12r was restricted.. Some people have said cams, others ecu, others clutch.. Iv'e watched the video Return of The Mach 3 a thousand times and the busa looks lame. Iv'e repeated the same roll ons with my buddies on busa's and have walked them just as badly.. Feasome K a reputable rider seems to be credible but not any substancial evidence from someone at kawasaki.. if the cams were changed what were the specs..

I have an 02 which is already restricted. I initially put on the bonnevile box and igniton advancer.. Then later an extended rev limit ecu. I have a full akro system and pc3r and my little k&n.. Its always been my goal to get the bike to the "fast specs" Does anyone have any ideas?

The 2000 model year ZX-12R is not restricted. It is considered to be the last year of the unrestricted motorcycles, for in 2001 the manufacturers went with a "gentleman agreement" and restricted motorcycles in stock fashion to 186.5mph (of course this can be removed).

I am curious if the ZX-14 will follow under this "agreement" or will it be everything Mama K has been brewin' in the Kitchen.

My 2000 model have been over 200 mph (recorded) at least a dozen times. No, it's not restricted.

to rac4it: youv'e been onver 200mph at least 12 times! Thats impressive.. What kind of set up do you run?

The only thing that I'm curious about, is what was done to the first batch of bikes they took back briefly before returning to the dealers...
It has been proven, in wind tunnel tests, that the Bus is more aerodynamic than the 12. 12's have more peak power to the rev limiter, just does'nt cut through the air as well as a Busa.
Many, many have gone faster than the Busa that's in the Guiness book.
He who has the bigger balls(or lack of brains?) when going up top will win.

Yes the 00 zx12r was restricted... by all its parts as a whole, to 178+/- countershaft hp and aprox. 162+/- RWHP which in turn limited its top speed to aprox. 195+/- mph.

Supra,
A ZX12 will break 200mph with Y2KZX12R's mods. I ran 202+ at Maxton following his
advice and trust me, at 200lbs, I'm no jockey.
All I did was remove my base gasket, degree my cams to 105/100, added Bears short stacks, Akrapovic pipe, PC3 and K& N filters plus a Muzzy timing advancer at 5 degrees. Very little money and time involved..........and of couse help from Jim (Y2KZX12R).

cool I have all the above mods except removing the base gasket which will probably take me from 12.2 to 12.8 to 1. I haven't degreed my cams yet and I dont have the Bear short stacks.. I do have the extended rev limit ecu with 2 degrees advance already in it.. I knew the new 14 wouldn't be necessary.. tank side up rubber side down..

Brian...

btw... old kaw boy and y2k what kind of dyno results did you get?

Corrected SAE was 181.x hp and 101.x tq. cams were 102.5/101 and the block shim (gasket) was still in. But sence that setup I flycut the pistons .015" on the intake side and advanced the intake cam to 101.5 and removed the block shim. It lost about 2 hp peak but gained 8-10 below peak torque of 7500. Its alot nicer to ride now. You dont need to ride it like a 600 now and keep the revs up past 7500 for corner exits anymore. It will pull clean from 6000 now.

How aout the test session Doug Meyer and Muzzy's did out in Maxton.

A STOCK 12 w/ Doug riding it went 192.3

ONLY changing out the Exhaust System yielded a top speed of 199.1

The 2000 12's were held up for six weeks to install a more restrictive canister on the bike. A stock 12 arrives at peak power @10,400 rpm. It also does NOT hold that power to redline. It can drop off as much as 11 h.p by 11, 500.

Remember what DOug and Muzzy were out to prove was Top speed and not measured Mile Speed. If it had been a cool day and even no wind, they would have gone over 200!

That is speculation. It was a brand new bike from the ground up. Its very common for production dates to slip. No one has ever presented any evidence to back up the statement that the bike was modified just prior to its release.
No bikes were ever returned from dealers. Nor were any parts ever sent to be put on the bikes at the dealers.
If they wanted to restrict the bike the cheepest and fastest way would be to retard the timing in the ecu. That would be a simple reflash of the eeprom. It doesnt get any cheeper or faster to remove power from the bike. But there is no proof of this.

I agree with Jim, I have seen/heard lots of rumors, even from people who were in Japan?? but there has been no actual Proof from anyone. I would believe that bike K would have fed simple changes to the aftermarket people for a quick fix even if they did something to please the Germans....

Ive never seen any 12 make peak power past 10,000 rpms.. Maybe because I'm in california. My 12 with my akrapovic makes peek power at 10,800 and holds it till it drops off at 11,200.. Are California 12's different from 49 state versions?

STOP THE MADNESS! "There was no restriction". restrictive canister? Where'd you hear that Psycho. That's a new one.
Y2 makes an interesting comment, though. Implicit in it is that the bike could have been faster and that's probably true. A few tweaks - timing map, cam timing, TWO MUFFLERS
(that alone would have come close) could have put the bike at or very near 200.
Keep in mind that if a well ridden bike went 192 in terrible air in .9 mile it would take 13% more power to go 200 in that same air and distance. And that the simple addition of a well designed, less restrictive exhaust nearly made that happen, yielding 199mph.
One thing that drives me totally nuts (sorrry) is the whole mismatched injector boot deal.
There's probably one or two hp there at best.
I believe that a stock (as delivered) ZX-12A, with at least 2500 miles on it with two mufflers and no cat's would on a standard day, in less than 2 miles go 200 mph consistantly.
Your friend,
Doug

BTW the Silver Book shows that many of the designs considered were two-muffler, even up to a model that was almost identical to the final bike. However I do not think it likely that that remained the case right up to the release date, that the bikes were pulled back to have exhausts swapped.

Most likely there was simply something being repaired, or if there was a change to slow the bike slightly, nothing more than timing, unless it was swapping for bigger mirrors, which also I doubt.

Okay Doug: Im just a novice asking questions... BTW how much horsepower can I yield with a 1270 or 1287 kit, with 2.5 degrees of advance, 105.5 /100 lobe centers and an akrapovic exhaust?

thanks

You would ask DM about an exhaust other than a "Muzzy"?? Pleaze!

Supra,
Mine made 183 on pump gas & 188+ on VP fuel prior to my Maxton runs years ago. Just dynoed it a few weeks ago on the same DJ250 and it made 181+ on pump gas, it now has 25,000 miles on it.

Where did this "the bikes were pulled back" deal come from, anyway?
There were some delays in the intro, (which is often the case) but bikes were not "pulled back".

Supra,
1270? Best I've heard claimed is a little over 200. Wth a Power Commander for proper fuel mappingI think about 190-195 is pretty normal. Without a PC I don't know.

As I said many times while on Mr. Muzzy's payroll, we tested all the pipes that were players in the market. I told the truth then and I will now- You can find a couple that will yield a higher peak number, but you won't find one that will yield more area under the curve and consequently, "perform" better.

Why would you think that the bike would have needed to be "slowed slightly"? Who, do you think, at KHI would have knowingly set out to try and be "second best"? That could only happen through incompetence, not by design.
D.

pardon me Mr. Meyer: I have just been reading a lot of postings over the last few years with a lot of claims.. Including some of my busa buddies whom I whip on a regular basis.. I have notice that many of the magazines are biased when it comes to the 12R.. Im glad to finally here your input and put this topic to bed in my mind..

sincerely,
Supra

This is a Blast from the Past

All this argueing about the only year 12 unrestricted with a 200mph speedo...

But I would take a 2002 and newer 12 over the unrestricted model...
