ZX-14 Diary – Part 1



Day 1—Pick-up bike on Monday, May 1, 2006:

diary2112:30PM – Received call from “Vista Jim” at Vista Kawasaki in Dayton, Ohio that my request for the first available ZX-14 to his dealership had FINALLY been fulfilled. Appointment was made to pick up the bike at 3:00PM.


3:00PM – Arrived to pick up bright red 2006 ZX-14. Naturally, my new leathers are black and blue, but as Murphy would have it, this bike was a ‘no match’ to any leathers I have ever owned. Damn, 66% chance of NOT getting red, and the red bike was the first to show. Oh well…I have parts to make, and the red does look good in a Ferrari kind of way.

3:45PM – Leave Vista Kawasaki with the bike (1 mile on odometer) to return to the office so I can show the new toy to the guys. Install a tank protector pad to prevent scratching from my jacket. Button up and leave for a quick trip home for more riding gear (2 miles.) Decide to take more scenic route home; arrive at home with 7 miles showing.

4:45PM – Depart for our dyno facility. Stop for 2 gallons of 89 octane fuel, although the sticker says 90 minimum. I hate 92 octane, it kills power! I want to run 87, but I’ll play it on the safe side with 89 on the new ride. Who knows if it will ping when it gets hot?

During trip, noticed heat from engine as fan turned on quickly—much sooner than most other bikes. Good! Better sooner than later.

Arrived at Dyno:

160 SAE/163 STD RWHP-Hot, 17 miles on odometer.

Bike runs way rich from 8K up to limiter. I’m sure it killed power, but how much? May be a built in safety feature? I need a Power Commander in a BIG WAY!

Guys on boards will swallow their tongues when I post these results! Oh well, I know better. Time for some break-in miles. Left Dyno for Tony’s house. Not excited about roll-ons with 05 GSXR-1000 making more power and weighing 100 pounds less.

The 14’s a GREAT bike to ride…even in heavy traffic. Heat from fan gets your attention, but the bike cools right down once moving again. Heat can not be felt while moving.

Arrive at Tony’s with 25 miles on odometer. After a brief talk with Tony, we take off for a ride to our favorite roll-on spot. (Tony rides in blind-spots…will have to speak with him about this.) We arrive at our favorite spot. Tony’s bike is at stock ride height. Must roll from 2nd.

First roll (with the 1000 in 2nd and the 14 in 2nd) -> Tony jumps 6-8 bike lengths instantly, and then we stay glued.

Second roll -> I hit from 1st, Tony in 2nd, and I smash limiter.

Third roll -> I missed 3rd gear. Adjusted shifter down so pinch gap matches dimple on shaft.

Fourth roll -> I try from 1st again. We stay side-by-side until I hit the limiter in 5th. Going way too fast to watch tach on a road! Neither bike pulls away. I’m impressed for a 14 to hang at all. Aero’s, Ram Air and big torque must be working very well together.

Fifth roll -> Tried again. Smacked limiter in 1st. Too difficult, Leave to go eat.

Tony rides 14 to the restaurant. Says that it’s smooth, powerful, and feels smaller than it looks. Rode his old Busa at Mid-Ohio; says he would like to try the 14 there also.

Arrive back at house with 89 miles on odometer.


Day 2—Drag Strip on Tuesday, May 2, 2006:


Dyno chart after 124 break-in miles

185 lbs in shorts before shower=200 suited?! Ugh…less weights and food, and MORE RUNNING!

Low Barometric Pressure–really hurts stock bikes. DAMN! It’s raining until 3-ish. Clears up enough for hope, so I leave work for shop at home. Yea!!!

Attach wrist kill, and add pump gas. Grab BP 93 from dirt bike trailer; no time to stop for pump gas on the way to the track, and I don’t want to upset testing with VP, etc… Adjust chain; add Brock & Vista stickers, 38 psi in rear tire, and 36 psi in front (new tires.)

Head to Two Wheel Tuesday at Kil-Kare raceway


Outline passes:
Summary of test session: Glutton for punishment. Try as ridden in Vegas, but TOO DAMN DIFFICULT TO RIDE. I don’t have the patience! Three 10.30 something’s, and I want a strap.


DO NOT preload shift lever before blipping gas! Lever will not return quickly enough after preload 2nd-3rd and 3rd-4th. 1st-2nd is perfect every time. Switched to semi-synthetic motorcycle oil, adjusted shift lever and chain, but did not help. Change in riding style helped most. Most likely won’t be an issue as bike loosens up. Called Gadson and confirmed that his personal ZX-10R had the same issue before it fixed itself with brake-in miles. Bikes in Vegas were broken in already– that’s what I get for ignoring break-in procedure!


Tell new ZX-14 owners to stay away from track before 1000 miles. I’m sure most will anyway.

Gas tank vent makes noise!!! Hissing stopped me in my tracks after loading bike.

Clutch is too soft for me. I can’t get the bike to move the first 20 feet. FIX!

9.70’s at 142?!? Taking almost a year off from the drag strip makes me feel very uncomfortable. I need MORE PRACTICE!


117 MPH 1/8 = 142 MPH…Basically the same as a Busa runs slammed with a clutch mod. Oh sh#t!! Rickey and Schnitz are ringers!! I feel totally average and too big to be fast anymore. WOW…if I am struggling so much, then what will the other new owners be doing? This is very frustrating. Are they going to be pissed at me, Scott, RG, KAWASAKI…???

Lowering Rear End

Lowering Front End

I did have the same performance numbers as the first day in Vegas, but a better ET due to chassis. Day 2 in Vegas was cold with a strong tail wind. Would not be fair to compare Day 2 in Vegas with today, especially in the MPH department.
Crap…it can only get better.

100 miles on odometer at the end of the night



Day 3 -> “Wrenching” on Wednesday, May 3, 2006:

Reconfigure ZX-10 Power Commander to function on ZX-14.

ZX-10R Power Commander being reconfigured to function on the ZX-14

Remove body panels and gas tank. Time consuming, but very straight forward.

No room to work! Ability to simply unplug throttle body connector very difficult. Very tight running PC wires, but accomplished. Little or no room for anything else.

The biggest item that will fit under the seat is a power commander…..you could fit a ham sandwich, but it will get smashed!

Success!! All tests positive. We now have tunability at the track! Send Dynojet a ‘thank you’ e-mail.

Noticed clutch noise in neutral when pulling/releasing lever while testing USB. Seems normal-just parts spinning. Shorten kick-stand. Received stock, base map from Dynojet. Thanks, Dusty! No time to test before hand, but the 100% numbers look correct to offset richness before limiter.


Day 4 -> Thursday, May 4, 2006:

Backwards!!! Head to track to test maps and try to get riding act together. Will have to get dyno map results later. Leave work at 2:30PM to replace body panels and get ready for track. Arrive at Kil-Kare at 4:30PM.

List passes:
Test summary: Most notable: Marc says to slip the clutch more. I do and get much more consistent ETs. 143.8 mph w/base map and no filter. Why is back-half E.T not better? Removing air cleaner nets “Busa-ish” response. ZX-14 wants to move as much air through the engine as possible.

*Last pass with no cleaner was on poor launch but MPH shows HP gain correlation on dyno.


Day 5 -> More dyno, test DJ maps and pipe on Friday, May 5, 2006:
Work. Day sucked.

So tired, and want to take a nap, but can’t. I AM NOT getting older! Must test BPP initial pipe for configuration. Hindle is waiting for go ahead on production!

Arrive at Dyno. Now that USB in on bike, I set the map to zero to test power. Test at lower RPM’s for Steven W. Semi-synthetic motor oil is thick. Run #7 is best–very rich.

Add map from Kil-Kare. Run #8 has very nice gains at high revolutions in over-run. SERIOUSLY, why no more MPH at track with the same map and filter installed?

Dyno chart after break in miles:

Remove air cleaner. Run #10 shows 175 HP = 143.8 MPH on last run at track. What the hell is wrong with this bike at the race track?!? I’m not small, but damn. Could it be me? Will have to find lighter jockey to test.

Busa would be running much more MPH, but, with oversized exhaust. Could stock exhaust be choking bike/ram air on track? I hope this thing responds to our pipe design on the track and Dyno. Look out for tar and feathers if not!

Test +/- maps wrong way. Base was good. I like USB versions.

Install prototype system: Gen 3 head pipes first, standard muffler, Gen 3  next Generation muffler afterwards.

THE STOCK EXHAUST WEIGHS 37 LBS 2 OZ.?! That is a 27 lb weight savings adding our Gen 3 system!!!

STUPID PROTOTYPE PARTS!!! Hindle guys shipped in a big hurry. Pipe won’t assemble correctly. Left tool at shop… HEY stupid me– Use WD-40 on assembly of similar soft stainless parts to prevent galling! Back home to massage prototype until 10:00PM. Ready for Dyno on Saturday morning.


Day 6 -> Dyno pipe configurations on Saturday, May 6, 2006:

Had I known prototype was going to fight me, I would have left the stock system on the bike! Another day would have been best to start with same set-up. Too anal! Get testing and head to Tri-state.

Dyno Test Summary:

Test various Hindle Parts before adding Brock Parts.

Try some tricks, but won’t respond at Dyno. Try at track later.

This chart shows the difference between the stock exhaust and our Generation 3 system with no tune, air cleaner installed using 89 Octane pump gas. This represents a bolt-on and go with the system.

Run #44 – Oil change. No AC, map, pump
No fresh MR9-Sh#t! Use old mix from the fall (in trailer.)
Not much gain-CRAP…more like U4 gain. Tune more, leave for track.

This chart represents the gains after tuning the engine with the Power Commander PC3usb on pump gas and adding our Alisyn motor oil.

Run #55 – Best after mapping even with junk gas.

This chart represents a typical everyday street set-up using Gen 3 system, pump gas and matching map in the Power Commander vs. the stock bike.

Marc arrives–YEA!! Pack up, reassemble bike pipe. Pipe fits body work perfectly! Great ground clearance for street system. I love when Lang and the guys listens to their drag racer!

This Chart represents the max power we obtained with our track tune up and map using the Gen3 system, Power Commander with map, VP MR9 fuel, Alisyn oil with the stock air cleaner removed.

Leave for track at 2:20PM. Call Gadson at Richmond Prostar 194 HP means 200 RWHP is on the way!!! Holy SH#T! What will this thing be like to ride?! It wasn’t so easy 30 HP ago! Obviously, Kawasaki boys KNOW stock exhaust won’t stay. BOY… were they ready for it!

Arrive at track at 3:40PM. Very slick! Eric all over the place on Kenny’s bike. I leave like a little girl – 9.56 @ 150.

Let (145 lb.) Marc ride to test back-half.

The passes represent a horrible 200 lb suited me vs. a worse riding 150 lb suited Marc Huelsman. As you can see the ZX-14 will still haul ass on a crappy pass with a light rider 153 MPH!

9.72 @ 153 mph! 122 in the 1/8th with 1.82 60 ft?!
8 Busas at track. Fastest one is Patrick at 147/8 (with my stuff.) The other systems present were all in the 143-144 MPH range. All stay out of our other lane. (He-He!!) They’re sick. Stock engine Busa’s USED to be fast… Ford vs. Chevy rivalry again…..sweet!

My 2nd pass – Bike lowered a bit more. Leave harder. Control wheel height for 300 ft. White smoke from front tire (Marc says) locked gas middle of 2nd. 9.48 @ 151.75, 6.24 1/8th. Will get 6.0s easy if locked in 1st. 9.20’s with a 200lb suited rider, stock wheelbase foot shifting! WOW!!!!!

Let Eric ride. The 17-year-old gets a look at the power and situational awareness needed with nearly 200 hp stock wheelbase. Acts like 1397 Busa ( 114 lb-ft?!)

Picked up a new can of MR9. I’ll need it to make 200HP!

Start thinking about chassis more. Need to keep bike on ground. Wheelbase, chain, bricks other tricks etc.

Clutch is nice. Haven’t even looked under cover- don’t see any reason. TOO NICE–check static and try to shim/spring for harder initial hit. Haven’t been able to get 1.5 anything in 60 ft. Most guys will add arm. Wow!! 8’s right now!

Gearing: Tranny and final ratio so perfect from factory that I have NO CLUE which direction will help. Trial and error…. Start ordering sprockets.
197 miles on odometer.


Day 9-> Dyno then track same day again Tuesday, May 9, 2006:

Added non o-ring chain to use the entire slot in the swingarm…trying to help 60 ft’s and reduce friction from stock o-ring chain. Rule of thumb is 1 tenth of a second for every inch of wheelbase length or more if bike is wheelie prone. Bike is VERY wheelie prone, should help quite a bit. Drained Junk fuel added new MR9.

Dean Shields at American Made (dyno partner) is THE MAN! Stops what he is doing for me to test on the way to the track.

Dyno Summary: Crappy day- BP way down correction factor 1.05 vs. 1.03 on Saturday. 195 RWHP today would have been 197-198 on Saturday. MAD about 195 HP out of a stock engine….GREAT PROBLEM TO HAVE!

This Chart shows a comparison on our dyno between a Busa and ZX-14 set up the same. Gen 3 system with Power Commander and Brock’s mapping, VP MR9 fuel, good oil. This Busa is the strongest we have ever recorded on our dyno- it is very fast….the 14 will crush it as soon as we make similar chassis modifications to use all of the power.

Kil-Kare Two Wheeled Tuesday is THE BOMB! Twelve passes with time to cool with fan in between. 41 psi in stock rear Bridgestone BT014 tire…hooked every pass.

Brock Having Fun!

Summary of track testing: HEY…maybe I can remember how to ride a bike!

All of this extra HP sure does move my not so light rear end in a hurry! Worst pass of the night is 9.48….best is 9.35@152.37 MPH backed up with 9.37@150.94 and 9.41@150.93 better than my best pass ever on a stock Busa and still over 1 tenth slower in the eight and 330. This bike hauls ass- period.

The passes shown represent my best two from Tuesday after I left the dyno.

Ran one poor Busa guy- he red lit big. I was giggling as I chased him down and blew past, it simply wasn’t fair. He could have had a dry shot and STILL lost….

As you can see, he red lit by about a week…so I gave him a clean break ;o)
He actually left pretty well, then the power of a properly equipped and tuned ZX-14 made his standard aftermarket equipped Busa like he threw out a parachute!


I wanted to test map changes to develop a track map to go faster… I didn’t need a map- I needed to get my riding act together! Will test map changes next, then move to track testing Street Megaphone and Sidewinder…BOTH made more HP at Hindle!!


41 passes, 63 Dyno pulls and two tuning sessions – 221 miles showing – over at track or dyno….I guess I should look at the clutch?!


221 no so easy miles!
