  • adjust IAP Fuel Maps for better race part throttle
  • adjust TPS Fuel Maps for better race power
  • adjust Ignition Maps for more race torque
  • Secondary Throttle Plate (STP) Opening Maps
  • Fuel Trim Maps for racing
  • Adjust RPM Limiter
  • Disable Top Speed Limiter if present
  • Disable Stock O2 Sensor for racing
  • MS0 map  light gr / bk ungrounded
  • MS1 map  light gr / bk grounded

Phenomenal? - Delimit your trackday or race bike.

Remove high rpm power restrictions
Change rev limiter
Modify ignition timing and fuel tables

"Phenomenal"? That may be pretty impossible to do on a 750 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.

As I recall -

After a race's worth of running over 100 AMA and WERA bikes, we gained from 2% to 3% power,

The least I saw was 1% (JR's super loose built engine) and the most I ever saw was 4% (on a super tight street  built engine).

The other 98 bikes picked up 2% to 3% power - with most 2% and  2.5%

Lasts 2 and up to 3 oil changes (tapering off in effect).

DAM!!!!!  my hats off to the people who did the R&D on the star! Man it shifts awesome.  Billy said my stock piece was already loose so it worked out great.  he says hi back at you.  anyways great product
thanx  -  danny

Evo Shift STAR
Specifically, the late style gsxr shift action is very flat feeling and gives very little tactile feedback as to confidence that it's really in gear or not. I hate it when you shift and you can hear the shift mechanism sort of  lazily "kathwaka" into it's "maybe" final gear location. I like a confident, proper "snick"!
They had it so close to "almost good"  in 99 - I'm not sure why they changed it for the "non-better".... Oh well - After redesigning and testing and redesigning and testing, and redesigning and testing...... I now see how easy it is to get it wrong, though.
We have a new detent "star" with a copyrighted profile (yep, the "science failed, so, it's artwork - so it's copyrighted) that includes a peculiar combination of compound arcs and radii that produces a shift action that makes it almost impossible to miss a shift ("almost" is the key word here!), especially 2nd gear in upshifts and all the downshifts - At least, if you miss 2nd, now, you will be REALLY surprised - cause it's now such a rare occurrence.
Downshifting confidence is 100% easier and better - just as important as not missing upshifts.
Beautifully machined on multi Axis CNC machinery, machined from solid Cro Mo steel bar stock, heat treated, Gold Zinc plated, a complex radii, beautiful part.

The star, arm and spring are located behind the clutch basket. 1-2 hours to install.

Ignition timing Tech

Dyne System
We use the EC997 Low Inertia Eddy Current dyne system, exclusively. It's fast and accurate load and rpm control allows much better accuracy and allows us to incrementally tune to finer degrees than common dealership level dynos. A lot of small increments add up to a significant chunk of power!
To see a good dyno (Factory Pro EC997....) do a power check at a 14k to single digit rpm precision click here  Try that with a dealership level dyno........

Tuned with Suzuki Denso Kit ECU (Yoshimura EMS Pro)
TiForce exhaust (only has one short muffler)
"Built" engine.
~131 True HP (as compared to ~120 to 124 on an AMAish 05 750)

Comments: I love this bike! It's as smooth as a Yamaha, clean, strong and handles beautifully!  Oh... and the TiForce is LOUD! Make sure you get this pipe if you want to scare women, small children, cats and dogs. Good power, though.

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.
