"Phenomenal"? That may be pretty impossible to do on a 600 with an ecu reflash!
But when you are talking small displacement bikes, a 2 to 4 hp increase in part throttle, midrange or peak power might easily be 5% to 10% better than a  stock or inelegantly reflashed ecu.

Some things are not possible to tune on a dyno and require track feedback to refine - that's why a simple "delimited" ecu reflash doesn't provide that last 10% of power or silky driveability that a track refined ecu reflash provides.

We have all learned that each bike, even with the same aftermarket parts, requires different mapping than it's identical twin bike. That's why when someone  "downloads the perfect mapping" off of some website for a pc or Bazzaz, that it only has a 10% chance of being perfect "on YOUR bike".
With 35+ years of tuning experience, Factory Pro knows that the key to silky smooth and strong  running is individualized, perfect tuning on each bike - That's why we do tuning for people all over.

Feedback on Pro Power Flash

I rode the race bike up and down the block yesterday and I'm really happy with the throttle pickup. You did a really good job with that. Thank you. I'll let you know how it goes at the track when I get out there. But I'm excited to ride it.

Shift STAR kit

Shifts 5 to 10 ms quicker -
decreases shock loading on gear teeth and shift forks from missed shifts.

No case splitting to install. Must remove and replace the clutch basket to replace the star. An impact wrench makes the job easy.
1-2 hours to install.


Easier shifting for street and track
Quicker shifting for street and track
Virtually eliminates gear breaking missed shifts

Helps protect the 6r's shift fork and transmission gears from damage during missed shifts under hard and easy use.

Installs under the clutch basket, no case splitting required.
Suggest using an air wrench to remove the clutch nut.
 Takes about 1 to 2 hours to install, depending on speed.....

This kit includes STAR only. The 07-08 zx6's already have a copy of Factory Pro's ball bearing detent arm and the stock spring is acceptable.

Positive feedback rating    Oh, the shift star works great.  I mean the Kawis have always been a bear to shift.  And the EVO cleared that up.  Love it -

Superflare Velocity Stacks - EC997 Dyno Developed

(lipped groove)

1. Choose your shipping method


Factory Pro's new patented stack design will update the 07-08 6r's to the latest higher hp spec stack type and then, even further, improve power with Factory Pro's EC997 Dyne System developed stack profiles and lengths.

The stock 07-08's are interesting in the intake tract area.

The throttle bodies and stock velocity stacks cross section is shaped somewhat like an old time western bathtub, complete with a head rest, but minus the suds. Not much going for it, as far as effectiveness.

We worked on the EC997 Dyne System with keeping the original shape and only modifying the lengths, but got essentially, nowhere.
With a lot of creativity and a large investment in molds, we created a round cross section stack and a unique rubber "oval to round" adapter that features Factory Pro's high velocity throttle body "stuffers" (as used on our awesome gsxr 750 and 1000 stacks).
We individually tested many different lengths and shapes of stacks and the zx6r (and 636) really woke up.

This testing was done with a Leo Vince race slipon. After we did the R&D, we installed a Leo Vince full system and picked up another 3-4 hp throughout the upper midrange and about 3 at peak. A REALLY good match for the stacks!

The chart below is JUST installing the stacks. A very nice improvement for a few $$ and about 45 minutes of owner installation time.

Unlike common dealership level dynos, EC997 dynos can easily be used to to tune the KRT, the Honda HRC and the Suzuki "kit" (sold by Yoshimura as "em-pro") race ecu's.
While a dealership might try to sell a pc and end up with, well, "tuned to a af performance", the Factory Pr EC997 dynos will actually help the tuner tune to the REAL correct af ratio - and that's the one that makes the Best Power -and it's different at every rpm and throttle position.
(a lot of guys with dealership dynos know that, but it takes too long to do on a dealership level dyno)

A dyno tuner and an
EC997 with the exclusive Factory Pro 4 gas EGA can tune a kit ECU in a reasonable amount of time.

When the southern Ca magazine bike projects need a kit ecu tuned, they use the EC997 dyno. Since there's no EC997's in socal, they drive 7 hours up north.

The picture to the left is a thumbnail of John Farkas' 06 636 that was tuned to Best Power.

Assembly Note!
The lower red allen screw is a shorter 20mm length to accommodate the rather generous external corner clearance bevel. The other 3 screws are 25mm long. All 4 are included in our cover. Our cover does not have a "through hole", like the "kit" cover.
The wire harness mount has been deleted (only two "spotting" holes are there) in the "Kit" cover. There is no possible way for the wire harness to move and hit anything.

Super detailed! If you ever wondered why "billet" engine covers are so expensive, that's over 1/2 hour of CNC machining, just in the interior, on about $300,000 worth of tooling and equipment. Also - the "blank" aluminum plate costs $50 to $60 each.

We have even less overall width in the lower regions than the "Kit" alternator cover (in background)>
Our cover has the optional .25" slider installed.

Hi Marc,
I ran Factory Pro engine covers on my rookie season in 2005 as a Novice rider with the CMRA.  As you know us rookies tend to crash a bit more than others.  I'm sure I'm not the first to say the covers and sliders ROCK!  On several lowsides throughout the season the bike slid on the sliders and never once tumbled.  I contribute this to the position on the slider on the bike.  Friends with conventional sliders found the slider digging in and flipping the bike causing much damage. Needless to say, my season ended in one Championship and two 3rd places.  CMRA seen fit to bump me to expert in 2006.  I purchased two brand new GSXR's and have already installed Factory Pro covers on the one through RaceworX in Dallas.  Unfortunately I had the chance once again on December 20th  at MSR Houston to test them out.  Once again they performed great!!!! The bike slid on the slider.  Beside a few scrapes on the plastic the bike was not damaged. 
With this said I feel like I could represent your product with much confidence! If you offer a support program I would be glad to participate.  As I said, I have already purchased a set for the Superbike.  I'm only in need of a left side stator cover for the 06 GSXR 1000.  Attached is a copy of my resume along with a rendering on the new paint scheme for the 2006 season.
I feel the your product has saved me a ton of $$$$ in crash repairs over the past season.
Thanks again,

Hi All


            Well the moon and all the stars have gone into alignment for me and I will be contesting 11 rounds of the WSMC with an eye towards the class championship in four classes. F-40, 650 Superbike, 750 Superstock, and 750 Mod. Prod.  This weekend was the first round and here is how it went;


            The first race was 750 mod. Prod. And having no points in the class from last year I was gridded in the last row, fortunately that was only the fourth row. This was my first race on slicks and I was very nervous about it. I got a good start and was in second on the first lap behind Cory Eaton about two seconds back. We started going through lappers on the third lap and by the end of the fourth lap I was right behind him. He got balked in turn eight on the fifth lap and I took the lead. He came right back by on the front straight and I stayed on his tail through one and two, then going into three I got up the inside and took the lead back. I was very excited to be in the lead and put my head down through to turn nine. I got on the gas a little hard and it started sliding before the apex, which was just enough to throw off my exit and I went through the dirt into the pit lane and barely got it turned back onto the front straight. That was all Cory needed and he got me by a wheel at the line. 2nd.


            Next was F-40 one race after. I got a good start from the second row and was second into one and first at the exit. I was going to try to put in some faster laps with the clear track and did for the first two. On the third lap I saw the fuel light on the dash and remembered I didn’t fuel the bike, OUCH! I put it in sixth and tried to baby it in, luckily I had done two sessions on Saturday no brakes and I knew I could run 28s with no brakes in sixth. So with the brakes and three laps to go I was praying no one would catch me and I would have enough fuel to finish. I did and they didn’t so I won. 1st.


            Next was 750 Superstock, this is the race I lost by a wheel last month and two seconds in November riding my 636 Kawasaki. Registration had some problems and when I looked at the grid I wasn’t on it. I went in and got that fixed but they didn’t want to grid me in my points position and instead put me at the back of the grid on the fifth row. GROAN. I was freaked out about being in the back and put my mindset switch in the KILL position. I got off with the group and into one on the outside. I have no idea how I did it but going into three on the first lap I was fourth! Second by the end of the first lap and shadowed Cory Eaton for the next four laps. On the white flag lap I took the lead into three and got under a lapper just after the apex of four and blistered to the line for the win. Latter I found out the lapper had held Cory up until six but by then I was gone.  1st.


            My last race was 650 Superbike. I was feeling good after the first three races and was ready for Chris Siglin. I got off good and was second on the first lap. My plan was to do the same thing and just follow the leader and only race on the last lap. At the start of the third lap Palazzo came up the inside of me entering one, I was able to hold him off but now it was time to go. I got Chris into eight but that was when I realized I had the suspension set up for slicks and I was now on 208's and there went the rear end and they both got me into one.  I had the bike sideways in eight twice and was getting spooked. I hung on and thought we might have a dash to the line with me getting the double draft. I went into eight about twenty feet  behind and right in the middle of eight the rear let go and got about 6 inches out before I caught it. That was it, they got at least 50 feet more in an instant and I lost the draft. Too bad because Chris got sideways out of nine and they both shut off, if only I had been closer. I finished third a half second back.

SHIFT STAR feedback

Aloha Marc,

I called earlier today looking for you but i was told you were in the middle of R&D.

I appreciate everything you have helped me with regarding your race 04 ZX6RR, the Shift STAR shift kit you recommended works like a dream. Real smooth shift with little effort.

The reason for my call was I wanted to ask you when do you think you will have an ignition advancer available and what timing do you recommend. I was thinking 4 degrees, what is your take. I don't have a dyno to see what works, so im looking forward to your expert advise. Thank you again and God bless.

MY Addendums and corrections to Roadracing World article, Feb 2005

"More Power!"


The 114.8 djhp that this zx6rr made in it's "pre-engine mod" stage 1, was the result of specially designed velocity stacks that we made for it, a specially modified ignition rotor to eliminate the max +/-5 degree limit that the KRT "kit" junior software has, a BMC RACE filter,  a very easily tuned KRT "kit" ECU, an Akrapovic exhaust and we used an EC997 Low Inertia dynamometer to derive optimal power settings.
It made that 114.8 djhp using standard, Los Angeles, low octane, low emission, California pump premium fuel (unspecified fuel type in the article).
It started out at about 100 djhp, with stock exhaust, as measured on the same dynojet dyno.
It was not simply "the only other addition was a Kawasaki kit ECU, as the article states -it was Factory Pro Stacks, Factory Pro Ignition Advancer, and Factory Pro EC997 Dynamometer tuned KRT ecu.

Regarding the Kawasaki KRT "kit" ECU: The article states that "only a handful of people have experience with it" - It's not that hard to use - They even were able to use the ignition part of it, so, even they can tune it - with no previous experience. Since the kit ECU controls fuel, and they could tune the ECU, why leave a power commander installed? (because a dynojet dyno can't provide adequate information.)

The bike ended up running VP Ultimate 4 fuel (U4)- an awesome fuel for adding power! It's 6% to 8% extra oxygen content over plain fuels generates 6% to 8% better power - all by itself.
(if one added VP Ultimate 4 to the 114.8 djhp that it made with good tuning on pump gas.... 114.8 + 6% to 8% = 121.7 to 124 djhp)

The bike made, according to the text, "an incredible 124.7 bhp @ 14,000 rpm" -
'BHP"  means "brake horsepower" as in on a load dyno - not an inertia dyno horsepower value.
There must be a difference, as the dynojet dynos read djhp, which is significantly higher than true hp - about 15% at the 100 true hp level, depending on which dynojet dyno you are comparing it to.

The graph doesn't show 124.7 peak power at 14,000 rpm - it shows 126ish - 127ish at 14,500 - 14,600 rpm.

Just to keep the facts straight, provide some background and reference values.

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
