600 Micro Sprint racers: We are big believers in the saying “Standing still is going backwards”, so we have been hard at work on several new horsepower projects… some are working with new motors, some are making improvements on older motors..
FYI: most of the motors we are building today are a significant refinement of those from even a couple of years ago, better rods, better pistons, cams, etc. We totally believe that dollar for dollar you will not find a superior motor to ours anywhere.

Don’t believe all the Hype! or suck up their Smoke.. there can only be one “best” injection system.
FTZ Electronic Fuel Injection!

We set out to do “electronic” right!
Born of being dissatisfied with all the micro sprint injection systems available, we spent many hard weeks of intense development to be able to offer our own fuel injection packages for the 600 Micro sprint motors.. borrowing on the best traits of those systems that came before,we have made the best of all worlds… offering the best low-end power, best top-end power, and the best electronics package. and yes we have tested the latest systems on the market, and all proved to make far less hp & torque in back to back dyno testing.
•Throttle Bodies: We use the excellent 2008-2016 Yamaha R6r throttle bodies with moving velocity stacks technology, same as the cutting edge new 220+ hp Ducati V4). This is the latest in motorcycle resonant pulse tuning technology. Yamaha got it “right” with this design. A fixed stack is only right over a narrow rpm band… and running different length fixed stacks is just a band-aid and no substitute for moving stacks. It just means those cylinders are “right” at certain rpms and “wrong” at others, depressing overall power. We have proven this time and again in our years of dyno testing. On the dyno, when the stacks open on our system the motor sounds like it got a shot of nitrous or boost! (These are now legal in Stock class, A class, Non wing and Restrictor for the all black Yamahas!)
In Micro sprint racing a wider powerband is more important than a peak HP or torque number. Everyone has to slow down for corners and traffic, and a good wide powerband is what will yank you off a slow corner and keep it ripping to the end of the straights.. giving you a real edge over the guy beside you..
We do away with the heavy throttle by wire motor and the throttle is controlled direct by the cable and the drivers foot.
•Injectors: We use 8 properly sized injectors- (just as modern 4 cylinder race bikes have for over 15 years now.) Secondary injectors mounted above the stacks just make more power, period… or else the OEM’s wouldn’t go to the trouble & expense (and neither would we.) Another advantage is you have your WOT fuel delivery split 8 ways. If you run 4 large injectors and one goes down say 10% then you suddenly have a big problem. Same if your injector tune is off by just a few milliseconds.. then your total tune can be way off.
We chose to use the best racing-grade alcohol rated injectors we could buy, made from stainless steel components and they are rated at over 100psi. We normally run them at 85psi for maximum atomization. Other systems commonly use cheap automotive gasoline injectors only rated for 64psi.
•Electronics: We choose to use only the best ECU available, the Performance Electronics PE3. No re-flashed stock ECU will come close to the features available with the PE3. It has fully accessible set up & compensation tables (most all of which we have overwritten to better suit the 600 micro’s). So not it’s just spark timing & fuel tables that is available to tune- it’s everything from cold startup, to coil charge times, to voltage drop compensation, and even injector timing can be accessed and tuned.. along with a myriad of trick options such as a fuel trim switch on the dash, or even a switch for a total map swap. We also have set ups for controlling radiator fans, safety auto-shutoff for fuel pumps, and can-bus connections to stream all PE3 data to a Mychron.
The PE3 also has built in diagnostics, along with signalling you with any system error, you can easily static test every sensor, every coil & every injector to check their firing, or pull up their signals on a graphic display on your laptop. So rest easy if you have a problem as simple as a yanked wire, as it can be founds in minutes.
Using the PE3 data-logging feature combined with our lambda controller we can pull up data logged from previous races to check everything from max rpms to coolant & oil temps, as well as air/fuel ratio during the race.. Then there is the awesome “color-tune” feature where the race’s air/fuel Lambda value is overlaid over your fuel table to tell us exactly where the map needs to be richened or leaned out.
You don’t get features like that from any stock ECU, you are lucky if you even get to adjust the ignition timing. These features have allowed us to send systems to race teams as far away as Australia, Hawaii, California & Washington State and subsequently been able to tune these guys better than if we had their car here in the dyno room, as these tunes are then perfectly tuned on their car and at their racetrack..
•Power: In our extensive dyno testing our EFI package has consistently made more power off the corner than similar R6r or Yamazuki systems, and more topend power over all fixed-stack 4 injector systems… and that has been verified on Yamaha’s, Suzuki’s, Kawasaki’s- from stock 599cc to full built Outlaw motors.. you name it… We accumulated several thousand dyno runs testing on this system and on the others…and we didn’t do all this to work be second best.
FTZ Performance is engine people– and always have been.. we have been finding the best way to flow air & fuel into these 600 motors for 25 years now.. We don’t sell wings, shocks, axles or bumpers- we only sell HORSEPOWER! Rely on our four decades of experience (that’s decades, not years) in motorcycle engine pulse/ram tuning & airflow expertise to extract the most power from your motor, and do it with an affordable, consistent, easy to use & trouble-free EFI system- using only the best top-shelf injectors & fuel system components combined with the best in electronics, combined with full-on customer support.
Complete packages starting at $3500..with the most popular package at $3795..

We are taking orders for upcoming season now…
So please get with us about your NEW options in electronic fuel injection for 2020!
**With the current NOW600 Series rules for Stock classes such as A class, non-wing and restrictor classes,
it now will be legal to use the PE3 electronics.. that’s great news! …and we now got that covered!

2013 & newer Kawasaki ZX636 Outlaw Motors:
One big project for us past couple years was been the development of the 2013 and newer Kawasaki 636 engines..
We finished that project after many weeks of engine work and dyno testing.. These motors were first rumored to make big power as right from the bike- but that has just not been the case in real life…and this has been echoed by other engine builders we have talked to0. The power was just not up to par with the faster Powri guys…..(well not until now..) after 600+ dyno tests we now have this Kawi motor up to our goal hp – and this set up and modifications are now ready for release.
The key? It was right where it is often found: in the cylinder head… With proper headwork, expert installation of our custom oversize valves, careful reshaping of the ports & throttle bodies then we were finally able to make the power we had been seeking…

Keep in mind these Kawi motors have never had the cases split, they are as came right from the bike, only the headwork, oil pan mods and clutch work have been done. This makes a very affordable engine build, without having to split the cases and replace pistons and rods, bore and Nikisil, etc.. No, it is not as fast as Nathan Benson’s full built Gsxr Stroker- but it’s not near the work and expense for custom made parts either..
This is simply a great “bang for the buck” for any 636cc legal motor rules..
So if you plan to race one of these new Kawi motors please check in with us. We have everything you need to make this a competitive micro sprint motor:
*Oil pan mods and custom pickup, (note: many of the pickups being made are of poor design and could lead to burnt rod bearings..)
*FTZ Headwork with oversize valves, this is where the hp gains come from.
* 6-spring clutch mod (stock clutch is very weak- it only has 3 springs like it is made to slip in the bike).
* Special design FTZ exhaust built just for this motor..developed during all our recent dyno work with this model.
* We have FTZ oil cooler adapters and can re-angle the water pump inlet forward so you don’t have to loop the coolant hose over the top of the crankcase anymore- risking an airlock.
*We also offer a complete FTZ designed EFI package using the excellent Performance Electronics PE3.. 100% developed in-house, all fully tested, perfectly tuned and ready to put on these motors and go race..
Please contact us right away for prices and options.

2008 & newer Yamaha R6R Outlaw or Stock class Motors:

** FTZ Level2 600 Porting & Head Mods

This headwork will help your motor, regardless who puts it together it.

These mods allowed us to produce as much as 10 more HP than without. Nobody else offers anything close to the craftsmanship that goes into this awesome modification package. Along with total reshaping of the ports and combustion chambers and installing our custom made oversize valves, we make special CNC billet pieces to raise the port floor, greatly increasing both flow and velocity in the intake tract, giving the motor a “supercharged” effect by increased ram tuning.

Announcing! The biggest advance in 600cc Micro sprint engine reliability!
The FTZ Oil Cooler Kit-
This is a life saver for your engine!
This uses the latest in hi-tech water/oil inter-cooler that mounts remotely in most cars, so you only need one cooler per car and one adapter per motor. For all popular 600’s. They are here and ready to ship!

for more info…. See the new FTZ Oil Cooler Page link here

Can be used with coolant temperature gauge above to monitor your oil temps..highly recommended!

A necessary item to adapt your vital oil pressure gauge or temp sender. Screws direct into the main oil pressure gallery for an accurate reading. drilled and tapped for 1/8 NPT pipe thread……………….$16.95

These adapters use an O-ring like the stock galley plug uses.. Don’t risk stripping the threads out in the block with some crush washer version of these!

*Check in the online store for oil pressure and water/oil temperature gauges and senders.

New Dyno- We spent weeks researching a new chassis dyno…and then after the decision was made we waited 14 weeks for delivery…and then the fabrication began to adapt it to use first with Micro Sprints.. this is what separates the rock stars from the groupies: You are now able to get your car tuned by people with our wealth of experience and complete engine building knowledge and on the latest “state of the art” equipment. No more second guessing the dyno operator skills or procedures.

Some history: Actually we have had an in-house engine dyno since 1991, and it has served us very well over the years in our product development- both 2 stroke and 4 stroke: Our exhaust systems, all our engine mods, ignition components, carburetor conversions, were all tweaked to the max on this machine. We have done tens of thousands of “pulls” and can tell you like with using any tool, precision results depends on the skills and procedures of the operator. But, because it takes so many hours to bolt a motor in and hook everything up on an engine dyno- plumbing, wiring, cooling system, etc. it has always been totally impractical to put customer’s motors on it for a “quick tune”, or for troubleshooting some problem. That will change with this new state-of-the-art chassis dyno. Plus if a guy has something like with misfire usually it is nothing to do with the motor, or even the carburetors- but some issue on the car such as bad fuel or fuel system , wiring or electrical problems, or even something like over-cooling. We have lost good customers over this kind of thing and it’s frustrating to know that we did everything “in shop” as well as anyone could- just to have some issue arise from something on the guy’s car. This new unit, combined with our experience, should give us the extreme accuracy we demand. So you can trust us to get it right- no wild or phony hp numbers here.
This is another part of the plan to make and keep FTZ Performance your best choice for superior power and reliability.

We have done extensive in-house testing with various 600 fuel injection systems in the last several months. We have always good power and dependability with our carbs, but technology marches forward and- as always- are seeking an edge.
Trust us to separate the truth from the “smoke” in this matter.

Check back often for updates on this and more new stuff coming online.

* FTZ Pleated Air Filters-

We had these cool blue filters made to fit better on the Yamaha R6 carbs, but they fit on the Keihen Flatslide FCR carbs as well. In our dyno testing on unrestricted motors, these 5″ tall filters made the best power by far, over any airbox………$24.95 ea. Note: When we were  dyno testing the 636 Kaw. we changed out a set of tall K&N’s with a set of these and gained two horsepower on the very next run!

*Blue filter oil……….$9.95 can *Custom made 4-in-1 Outerwears for these filters…….$29.95

Hot: * FTZ 600 Exhaust Systems-

For most all 600’s- for the Yamaha R6 & R6r, Kaw.636, GSXR600’s and Honda 600RR’s. This is our unique design we specially developed for the 600 motors. We have seen over 8 HP increases at certain rpms over our earlier exhaust designs. We have been told by other’s dyno testing that this pipe made up to 10 more horsepower than other brands of exhaust. Don’t ignore this important (and legal) tuning aid. Adds both torque & horsepower… Comes complete with our tapered core muffler with Stainless steel shell and exhaust springs & exhaust gaskets……$595 *Ceramic coating is available.. coated set $695.

We have developed a special Exhaust System especially tuned for the 2006up Suzuki GSXR as well as the 2006 to present Yamaha R6 motors-as well as the 2013up Kawi 636’s. more hp!! same price!

We are one of the only engine shops that have in-house CNC machining capability- If we need a part made better- now we just make it ourselves!… this is a real advantage.
There will be much more to come. Got any good ideas for parts needed? Let us know!
