Super tuning for 02 ZX12R
Hey,
I recently purchase a 02 ZX12R. I installed a full Muzzy system and a DynoJet Power Commander IIIr. The bike is really sluggish under 3k rpm. I am going to change the front sprocket to a 17 tooth. I think that will help mask the problem. The bike runs great after 3k rpm.
Does anyone have any other suggestions to tune out this problem?
What voltage should the TPS be set at??
Your suggestions are appreciated.

I have an 02 and my TPS is at 214. The bike is still not be developed but Ricky Gadson is running his in the 60" class on NOS. Maybe him or Doug (Muzzy) will post some info, a magazine wrote he is using a 40 shoot of NOS 1270 Muzzy kit (soon adding a 1361 crank) and running 8.75 @ 160. I would like to kn0ow about the clutch and other stuff he has done, But i guess its a secret.

Yea,
I guess thats why you gotta gear'em. If the bike was carbed it wouldn't be a problem cause you could tune that flat spot out. My guess is that fuel injection has a way's to go yet...Sprocket goes on tomorrow. Well see...

looks like if you want to get the most out of your bike..you have to go custom.(there goes another 150 - 200 bones)

When you hook up the PC3 to your computor with the supplied cable look and upload your map look under throtal position it has a closed and opened section. It should be at 0 or 1 on closed and it will show a number for open (214). With the bike key turned on but not running open the throtal to max and see what the number is. If the numbers are not the same, then set it by clicking the set button on you desk or lap top sofware with the throtal in the max position.

KCABY,
Wanna share some details on the map?? What mods did the bike have? Did you run it on a dyno for comparison of the before and after results? Wanna share the map? I would luv to try it myself.
All,
I changed the front sprocket from a 18 to a 17. This helped mask the problem. The only time you see the flat spot is if your in first gear puddering in traffic. With stock gearing you could get killed in an intersection or cruising through a parking lot with no throttle response in first gear. In my opinion the bike responds better with this gearing anyway after installing a pipe and PCIIIr. I think if I was competeing for a top speed king that this would be acceptable. Everyday drivability is more important and a safety factor. Notice that the box stock ZX12R doesn't have any dead spots anywhere in the powerband!
This bike is made for top end performance. 7k rpm and above is where all the power is. Example:
Kawasaki has always been a high rev motor vs Suzuki which has always believed that mid range horsepower is better and keeping the rev's lower. I have owned both and I choose the KAW for the top end rush. It's like a turbo charged small CID motor vs a big block torque monster. That's why the Hyabusa is such a great motorcycle. Its like driving a big block Chevy vs a small block which loves high revs.
Sorry I got on a rant. I think I speak for a lot of people who purchased high performance parts for the ZX12R and were not told that there would be low end performance issues that could get you killed. I have tuned many carbed bikes and have never had this problem. I think that it has been unfair and bad practice for performance manufacturing companies ( not mentioning any names here) are putting out products that suffer from such a low end power deficeincy that it is a safety risk just try to get into traffic and not tell us that this problem exists. I know that when I bought my products there wasn't anyone saying try this at your own risk because the vehicle you put these products on won't get out of it's own way under 3k rpm and could get you killed when you stall it at and intersection when a Cement truck is coming at you!! I am dissapointed with the perfomance of my mods on the bottem end of the power band and that I am left with trying to re-engineer my machine to operate safely and find a "work around to solve the problem".
I expected a finely tuned machine when I purchase all my parts from one vendor, just like in the past when I installed jet kits and pipes. If these companies need more time to figure out the fuel injection systems to make it safe then do the research or tells us what to expect. I expect a product that improves the whole performance of the bike not just part of it. What's even worse is to call a company and say hey, this thing has a problem and have the companies say " yea I tried everything and that's the best we could get it to do"
I don't feel that a "custom map" should be needed. I feel that if you buy all your products from a "performance company that dyno tests the products that they sell" all the parts should match and work in harmony together.
I know based on what I have read there's a lot of people that are in the same position.
I would be curious to here what other people have experienced buying an exhaust system and a PCIIIr.

Owning a Dyno, I can only say that todate I have not seen a single pipe manufactures map be the the so called perfect map for the motorcycle in our shop. That said, I don't see how it could be. Every single head, valve, piston, ignition system , exhaust sytem, etc. is not exactly the same. Not possible. So the Manufacture whether it is Muzzy, Acro, Arrow, TiForce, Yosh etc. do their testing and come up with a good safe map. From there we can fine tune the bike and give you a refined ie more exact map based on the bike.
That all said, if a guy or gal is not looking for perfection or the most he can get the manufactures map is usually good and or safe. What I must admit is amazing to me is the fact that there are folks out there that buy a $12,000 motorcycle, purchase a $900 to $1500 exhaust system, a $300 power commander and any other number of trick items and then pull up and say hell no to a custom map.
We mapped a Harley today that the guy spent $22,000 on it to buy it, spent another $12,000 to have the engine built with all of the trick stuff and after some coaxing from his engine builder he sprung for some dyno work and mapping. His bike came in dangerously lean. Meltdown city lean. It cost him $100 for us to do the work. His bike makes more horsepower then he or his engine builder thought possible and it's safe to ride. I do not have an MBA in business, but.... seems like a pretty easy decision to me.
I am not certain of the issues KGZX is talking about above regarding low end and how the busa is a great and like driving a big block chevy. I know of many bikes with those characteristics, a Suzuki Intruder, Goldwings, VTX's Harleys etc. It is kind of like complaining about a Ferarri not being any good for towing the boat.
