you can rev the limiter by 700 rpms safely. To get more power out of the stock cams you'll have to degree them 105/103 or 105/100.. Some folks have put the intake cam on the exhaust side good for 5 horsepower..

fearsom k seems to think the pre production zx12 r had 5 degrees of ignition advance in the ecu, the intake cam on the exhaust side, and a higher rev limit. Also 18/45 gearing. The above comination should attain 200mph easily even with the stock pipe...

excuse me you can raise the rev limiter by 700

Yea, how do you do that without sending it off to have it changed?

I did it through superbikemike in florida. added 2 degrees of advance and extended rev limiter 700rpm. On the tach in now tachs out at about 12900 rpm but actual is about 12,300. I don't know how to get it done without reprogramming the ecu. Powercommander has a rev extend feature but I don't think it can extend the rev limiter that far.

Interesting Stuff Guys!!
Ok - so let me get this down :
Step 1 - send ECU out to superbikemike to extend rev limit by 700 RPM
Step 2 - program my Power Commander IIIr to +5 Ignition Advance at high RPM's
Step 3 - ?? Not clear on exactly what to do with my cams?? CAn someone help out?
After that the bike should be in full "modded" form right? Then I'll just take it to a DJ-250 shop to re-map her to perfection and be done?

Step 3 put the stock intake cam on the exhaust side..
advance your timing 5 degrees with the Muzzy rotor it works decidedly better than the pc3r.
don't forget the pre production 18/45 gearing. Your bike will spin the dyno drum past 200mph( iv'e done it)

Wow Supra... someone should call the "mags" and tell them to write up a conspiracy theory article - would be a great read! OK, here is my plan for this summer:
1. Send ECU out to superbikemike to extend rev limiter by 700 RPM
2. Put stock intake cam on exhaust side and exhause side on intake (can you verify the swap of exhaust side to intake, or do I get a new intake cam to put on the exhaust side and keep the existing intake cam?)
3. Put a Muzzy timing rotor on at +5 degrees advance
4. Drive bike to a good tuner with a DJ-250 and get a full re-map
5. Put in 18/45 gearing....
6. GO 200 MPH!!!! WOOT!

correct. just get a new intake cam and put it on the exhaust side. the cam angle sensor will have to be taken out. Call Lees Performance in NC he does this mod. APE racing does it too.
btw the intake cam has .358 lift and the exhaust only .342 the intake cam also has more duration..

wy that gearing????
acording to my math
18/46 = 202 mph at 11600
18/45 = 207mph at 11600
but at 12200
18/45= 217
18/46= 213
you dont need the more rpm to get in the 200mph

your math is correct. However mathematical calculations are different than actual.
you'll have to re-read the beginning of this thread...

I just got back to this thread. I personally never did the wiring mod. At least not yet, as I have been focusing on my 05 GSXR1000 since Nov. (Love that bike!)
However, just thinking about the mod, it would initially seem that connecting the wires for 4th - 6th would not fool the ECU. However, disconnecting the wires and then running a leads from the 3rd wire to the connections on the drum would do it. ?!? Because when you shift a signal is needed while the drum is in 4th-6th otherwise it would not recognize any gear.
I would need to see what the OEM A/F is all the gears to really know if 3rd gear ECU info is better than 4th or 5th? But, I understand the logic behind the mod.
Having done ALOT of street racing and roll on with the zx12 starting in 2000 Magazines were really OFF REALITY! Most all busa guys on the street KNEW and KNOW that the zx12 was faster. And even crazy faster with a good gear for roll ons starting at NO LESS than 4500rpms, that was easy money. However, aftermarket modifications gave the busa the long term edge. Now a HUGE number of busa's are modified with 1397 kits and head work with cams. They look stock and are streetable like stock, but are faster than a STOCK zx12. The busa's stroke allows them to make more torqure easier which translates into acceleration for 1/4 mi racing.......ie lower E.T. (if you can ride it......smile)
This zx14 is faster stock for stock, but I don't know anyone with a stock busa!!!

...it all makes sense to me now....I remember reading somewhere (probably here) when all of this "speed restricted" stuff was all the buzz...the person who said this was someone who was 'in-the-know' about the ZX-12R's developement...when asked about the bike's speed restriction, he essentially stated, "Its so obvious and in plain sight."....I take it to mean that the bike's behavior at 200+mph made the engineers tweak the engine for less power or they would have had to redesign the bike's aeros and looks to attain better stability at those 200+mph speeds...then the bike would not have looked as good as the 12R as we know it...and now look at how controversial the ZX14 looks asthetically....

How much more power does the bike make with the cam and timing mods (and a good tune)? My baby's got about 175 to the rear wheel now with just a muzzy pipe and PC-IIIr.

Nifty! I think the problem is that Doug's bike did 199.1 with a lighter/smaller person on it than me  . i'm 6' 2" 210 lbs... might need a few extra ponies to haul my butt to that speed..

Sounds about right supra....
I went 184 with my unexpirienced 6' 1" / 230 lb. ass on my 00' stocker.
Using Dougs exact pipe, advancer and map (only mods), I went 196 mph on the same bike.
I only wish that I would have sealed up my Ram_Air system BEFORE this test.

so your argument telling me how a bike will go over 200 easy with the stock pipe and your other mods...is to throw out a example generated by one with an aftermarket exhaust on it?

Would webcams work as well or better? They are 1/2 the price of Muzzy's. How much does a stock intake cam go for?
Thanks,
