08 14 Info to share
Some of you may already know but others may not...here is a list of the technical changes compared to the 07.
Revised piston crown, the piston diameter was increased by .05 mm, the 07 was 83.42 mm, this increases compression sealing.
Injectors were changed to a 75 micron as compared to the 07's 80 micron. Revised intake port and injector angle for increased combustibility. Revised spray pattern from 15 degrees to 20 degrees.
New clutch primary gear...no need for the old scissors gear. The revised gear shape optimizes pressure angle for quiet operation. The primary ratio has been revised as well to 1.556 ( 84/54 ).
New polyurethane dampner on the countershaft cover to reduce noise.
New die cast sections in the frame increase rigidity and reduce weight.
The exhaust info may be a waste of typing except for those running the stock exhaust.
The header section has a 75% wider mid-section, revised balance pipes, increased the head pipe diameters by 6 mm...all of this relates to improved mid-range performance. The cans have revised chamber ratios to increase flow and lower db output.

So what does all of that mean more horsepower or less horsepower? Any motor guys out there please explain

slight RWHP 2-4 hp increase across the curve, and improved throttle response.
with a better flowing mid pipe, and head pipes, I think slip ons will fare better than they did last yrs,
... just conjecture and eductaed guesses, I haven't seen one on the dyno yet.
Forgot that the ecu has been changed with revised ignition map, and the flies open sooner

The changes have resulted in more horsepower in the low and mid-range areas. HP is in the 161 to 162 area at the wheel and torque at 102 ft.lbs depending on dyno and conditions. I really like the higher torque number, after all that's what gets the mass moving, good HP will keep it moving. The new 14 is also 18 pounds lighter with a full tank of fuel than the new Busa. All the math works out better for the 14. In the real world with all things being as they are, the 14 in stock trim should best the Busa in stock trim in the quarter.

Great info Kawabunga; thanks! One question though; the primary ratio resulted in lower or higher gearing in 1st? I ask because I'm about to install the 16/43's and am curious as to whether I'll see more or less punch in1st over the same mods on my 06...
Lyle -- finally got the box today! Work starts on Monday.

All that i have read about the 08 14 is falling its face on the top end because of the A/F ratio.
Anyone with a 08 14 or know someone with a 08 14 thats has fixed the A/F ratio on the top end with a PC3 and does it really weak the bike on the big end?

Old primary was 1.541 (94/61)
new primary is 1.556 ( 84/54 ).
Primary is the gear ratio off the crank to the tranny. All gears are effected.
All gears are slightly lower, but not enough to notice Steve.
Only 1 % change.
Glad to hear that Steve!
Did you have a look at your new toys?
Nice shock eh! a work of art!

I'm running Brock's 08 temp map on mine, and i think the top end is fine. Havent had it on the dyno since stock, but definately stronger with pipe/pc/and map.

No problem, I am here to help you guys any way I can. 2008 is the year of the Kawasaki....Rob & Ryan are gonna kick some ass this year in NHRA....Kawasaki will dominate AMA & World Superbike....Moto GP should be interesting...early testing has the Kawasaki a little behind but I believe Hopper will do well and with the Monster Energy sponsership... lotsa publicity. Suzuki, Yamaha & Honda will all have to go back to the drawing board after this year. Kawasaki...the alpha bike. I can't wait till racing season !!!

08 mapping
I have to agree with silver08, I have ran the brocks temp map and the akrapovic one from dynojet. I noticed a very good increase in the mid to top end pull. On the last bike I pc'd the butt dyno didnt really show much improvement. This really seem to wake this bike up, so for those reading all the info about rich top end, this cures that ill. Still dont see why Kawa richened this up like they did though??

Hurry up and get that thing together so we can see how it pulls against an '06

Dub& Kawa,thanks for conferming that I picked the right bike and using slipons will give me all around best street riding after gutting the the big collector..of its plug. If you study the 08 stock header you will see a lot of design and work put into them.  EEP. Every year It gets harder and harder to improve on the stock systems.

BUSAJACK-- That striping looks great on you're MSblue 08. I have been thinking about doing something similar on mine for some time. Maybe this summer.
So, people over here are in favor of removing the collector cat? I've heard of it being done but never heard about any performance gains as a result. I was just about convinced the best way to go would be get rid of the whole stock pipe and replace with a full system.

I just pulled flies on my 08 but I have not had the chance to test it yet. I've heard the throttle is a little touchy in 2nd & 3rd gears with the flies out. What do you think about that?
I also planned to try a DIY TRE.

Regearing a ZX-14 is cheapest and best mod you can do. I have slip on's (for now) and beat a stock geared 06 ZX-16 with a full sysytem etc,really bad. It was really a Big gain doing a 80 in high gear roll on. I just pulled away and we both weight the same. Next week he came back over with a 43 rear and Big difference. I could pull him for a few seconds then he will catch me and go by. Time for a 421 exhaust and new map and add 1 more tooth to rear.

Nor did the updates mention a different air tube redo on the throttle bodies that use smaller rubber tubing [say ounces of weight loss] on the '08 than on the early model throttle bodies.
