6+ True hp at 12,000 rpm
4.4 True hp at 13,000 - 14,000 rpm
 with just a change to the new Factory Pro Billet stacks and fine tuned with TEKA SFI

The 00-05 Suzuki 750's, unlike most other bikes, change fuel delivery rates to the slightly leaner side or the richer side when stacks profile and lengths are optimized - or sometimes richer, as the case turned out to be

The  BLUE  line is the Factory Pro V Billet V Stacks, without fine tuning the stock computer with a Teka SFI Fuel Injection tuner. Better than stock at every rpm point.

One thing that I'll throw in here -

For years, most professional tuners have been aware of the sag in power at 12,000 rpm - It's there on most stock 750 Suzuki's and you can even see it on a dynojet dyno.

The  RED  line is with the addition of Factory Pro Billet V Stacks, with a few moments of care, tuning on an EC997 dyno with the Suzuki tuner's secret, TEKA SFI.

The  GREEN  line is the stock stacks with Yoshimura exhaust and BMC or K&N air filter

The stacks that we developed look nothing like the stock rubber stacks and we seemed to make more power at every rpm point and there's not a hint of a power dip at 12,000 -

GSXR Transmission Shift Mechanism Kit
The "Paddle Shifter" for your foot -
The 00-05 750's (and 1000's and 600's!) need help in shifting. Track tests report that 2nd gear had a repeatable ability to pop out into "neutral" under hard acceleration.
Aside from that, 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 final gear location. I like a confident, proper "snick"!
They had it so close to "almost good"  in 98-99 - 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 particular 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. 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, also. Maybe that's just as important as not missing upshifts!
I'm happy with the "star" and couldn't possibly change it for the better and I figure that it will take Suzuki 2 years to copy it!
New manufacture:
Beautifully machined on 8 Axis CNC machinery, machined from solid CroMo steel bar stock, heat treated, Gold Zinc plated, a complex radii, beautiful part.

For the quickest shifting - use this spring, too.

If using a quickshifter, you MUST shorten shift kill duration TO  to 45-50ms.

The Suzuki ECU tuning tool the industry has been missing until now.

Teka  "SFI"  Fuel Injection Tuner for Suzuki.
USA NATIONAL Championship Winning Performance!
2005 Hooters / Michael Barnes / Full Spectrum - 6 US track records!

Wide range with fine increments - perfect for late model FI Suzuki motorcycles.
Taking the Fuel Injection by storm.

Most reliable of all FI fueling tuning tools.
Does NOT lose maps or cause ignition scatter (more high rpm power - better low rpm smoothness.

Teka allows the user to dial in Suzuki fuel injection systems. Adjusts low speed / idle (unlike other permanent add-on boxes like pc/yems) and also adjusts different ranges of throttle opening, up to and including full throttle.

IDLE CIRCUIT: Make changes as bike is running, real time, unlike other FI adjuster boxes - absolutely saving time when adjusting the low speed mixture. Select a cylinder and make it richer or leaner - as the bike is idling. Just like adjusting fuel screws - except you don't get your hands dirty!  Makes idle adjustment a 3 minute joy instead of a 15 minute, vague, aggravation!

RUN CIRCUIT RANGE: Make changes as bike is running - on road or dyno. Teka extends the range, as compared to Yosh box, from max. 10 to max. 20 for those high hp applications and when you need more fuel, like our 2000 model gsxr750 that thrived on +5 at part throttle and +15 at Mid Throttle and -2 at Full Throttle.

Teka provides smaller throttle position increments, too. 1% to 10%, 11% to 25%,26% to 50%, 51% to 75% and 76% to 100% in proto Teka. Addresses Hayabusa off-idle glitches, where you need to richen up the "very small throttle opening" or just above that to address "hiccups".

Check the fueling on your local Low Inertia 4 Gas EC997 dyno, adjust the stock ECU for maximum power, set it and take your Teka Fuel Injection Programmer away with you.  That's good for 1-2 True HP over pc2 on a Hayabusa installation when tested under load on real dyno.

In progress.
The TEKA FI system is an add-on box that either intercepts sensor signals before entering the original ECU (Engine Control Unit) or modifies the FI sensor or ignition coil outputs after leaving the stock ECU - or a combination of the two, in order to modify ignition timing and cylinder fueling for increased power.
The unit is an advanced example of the pc2 and 3 concept and avoids the pc2's power losing ignition scatter problem.

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,

Marv Esterly

pn: RTR-SUZ-37-XX  -  ignition mount plate install and tech

application: gsxr600 / gsxr750 / gsxr1000, 1996 to 2005
(and 06/07 w/ different instructions)

tools required:
5mm allen wrench
#2 philips screwdriver
medium flatbladed screwdriver
Razor blade or Exacto knife
gasket sealant
14mm socket
air wrench

A look in.

Location of ignition trigger mounting plate on:

gsxr600, 97-05 (and similar)
gsxr750, 96-05(and similar)
gsxr1000, 01-07

1. Remove the outer "palm sized" small starter cover   (already removed).

2. Remove the inner, larger starter clutch cover (already removed). Remember, there is a screw in the upper left of the inner cover that is not accessible until the small, outer cover is removed. You will probably reuse the gasket

3. Remove the starter clutch bolt with a 14mm air wrench (that's the easiest and quickest way).

4. Remove the original ignition plate from the engine cases with a #2 Phillips screwdriver. (it's under the starter clutch gear)


5. With a flatbladed screwdriver, remove the ignition trigger coil from the original mounting plate and reinstall it onto the new Factory Pro ignition plate.
Be careful NOT to stab yourself with the screwdriver!

Note: The gold center core plate (at B, down arrow) of the coil assembly MUST extent "proud" of the surrounding off-white epoxy area when installed and tightened. There is a small amount of play to adjust with, and it must project outwards, towards the ignition rotor, usually ~.005" to .010".  (In other words, a real little bit)
If the center core is below the off-white surrounding area, the voltage produced will detrimentally affect the ignition system and make the engine difficult or impossible to start.

6. After installing the trigger coil to the ignition plate, temporarily reinstall the starter clutch and bolt and rotate the engine so that rotor projection at B, up arrow is aligned with the trigger coil (so you can measure the trigger coil clearance).

7. Install A-1phillips screw, snug. Install  A-2 Phillips screw and snug down.

8. Measure the clearance at B. It should be .015" to .020". Adjust by loosening A-1 and A-2 and pushing the plate towards the rotor. Tighten screws when done.
 .040" pickup coil to ignition rotor clearance will make the engine difficult or impossible to start.

2.  So - you cracked the magnet because you didn't line up the locating hole......
     It's OK - just put the 2 pieces together and retighten the 2 flat bladed screws. Lucky you!


dynoroom,onramp,toright.jpg (198084 bytes)

Question: If .040" clearance will make the engine difficult to start, and .020 starts well, is .010" better? Haven't had time to test that, yet...

9. Check the tightness of the coil plate screws, reinstall the ignition plate. Use a bit of light strength thread locking compound on the screws if you want, for a good job.

10. Reinstall the starter clutch and mounting bolt. BE SURE to line up the indexing marks on the crankshaft end and the starter clutch or the TDC marks will be wrong and that could cause big problems if using the TDC marks to adjust the valves later.....

11. Reinstall the covers (don't forget the screw under the small cover). Replace or reseal gaskets as necessary.

12. You should not have any parts left over, except for the old ignition plate.

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.
