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 map" 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 the west coast and Nevada.

Thank you Marc.  I have just one word for the bike: awesome!
It seems to be running cooler than before, and has so much more torque in the mid-range.  Not only smooth but it pulls like a freight train already at 6K. Really cool.  Sounds better too with the v stacks.

06-10 600 stacks work the same

Want to do "something" to gain some more more power?
How about adding a big triangle of power to the topend, + 2 True hp to the original peak and make a new peak that's up to 4.5% True HP stronger than original - Extend the power up and past the stock powerband's natural end.
|Is it always going to be 4.5% - No - it might be a bit more and it might be only a few - but - even if it's only 3 on your bike, it's still 3 you didn't have before and it's still an extra 1000 rpm you didn't have before.

Billet Superflare Stack power peaks

Hi Marc
Just to let you know the GSXR600 we got ready for the Manx GP with your velocity stacks and ignition advancer (2 deg) was the fastest 600 on the island for the whole 2 weeks!!!!. 168.80 mph through the speed trap and finished 4 overall in the senior race with our rider Ivan Lintin onboard. Getting the 600 ready was all a bit of a rush due to sponsors dropping out last moment!!! So we only had time to port a head and skim it and set it up well with no cams so we were as surprised as everyone else just how well it went, 120 hp from 113hp (dynapro figures rear wheel). We have a SV 650 to get ready for him now do you have any goodies for that too? Many thanks regards JON.

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, a complex radii, beautiful part.

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

What the difference between the 06/07 and the 08-10 throttle bodies?

06/07 and 08/09 - They are both 40mm primary butterflies
The 06/07's throttle bodies are about 39mm diameter at the engine side of the throttle body.

The velocity is high where the primary butterfly is, but drops off when it dumps into the 39mm area downstream of the butterfly (as the cross sectional area increases, with the same air volume).

The 08's neck down to aprox. 36mm across the port entry.
The "36mm hole" flows more near the same as the 40mm area with the primary butterfly.

The 3mm smaller 36mm cross sectional dimension makes the intake tract retain higher velocity and that makes the "tuned intake tract" factor potentially even more effective (if you get the v stack length and profile just right)

You may have noticed that some of Factory Pro's Superflare 1000 and 1300 stacks feature a smaller diameter ID as compared to stock and other aftermarket stacks?
"V-e-l-o-c-i-t-y" is key.

On the later 600's, our testing indicated that the stock stack ID is pretty good, so, we don't neck down the Suz 600's Superflare stacks.

Artisan Crafted Fine Cheeses – Since 1865       

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


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.
Edited to the tunes of Chemical Residue by Herbie Hancock.

Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
