Hey Guy's!! Just a little peek on some of what is new at FTZ
600 Microsprint racers: The "gears" are always turning here, and we are big believers in the saying "Standing still is going backwards", so we have been hard at work on several new projects. Yes we still recommend the same Yamaha R6 and Honda RR motors that we have for several years, but please keep in mind there has been many improvements on these along the way and the current motors are a significant refinement of those from even a couple of years ago. We believe that you will not find a superior motor to these anywhere.

So here is a sample of some of the new things going on:


1) GSXR600 Suzuki-
We are continuing to work with these motors, applying our bag of tricks to them and getting special parts made for them. We are very pleased how the results are turning out. On carbs or injection this is a viable option that you will be seeing more and more of. It appears that you will be seeing one of these on a certain #22 car this year. So if you are thinking you want to try something totally different this year-- then get in touch.

**Sold**: FTZ built Suzuki Gsxr motor. +2mm 636cc
All the best speed tricks and custom parts used.
The head is fresh off the flowbench with impressive results. Ready for carbs, EFI, or MFI.
....call for more details and pricing.


2) Lightweight Carillo R6 rods-
Well it appears that 6 years after I suggested that Carillo make some lightweight rods for the Yamaha R6's they have now finally decided to do just that. They will soon available for both the older and the newer model Yamaha R6s. We tried the standard Carillo rods in these motors over 6 years ago and soon had bearing failures in those motors. These are considerably heavier than the stock rods, which just added more load on the bearings at high rpms- Note: The stock rods are actually strong enough to carry any load these motors can dish out, but some guys have managed to bend the beam of the rods causing the bearing to then bind and fail, and usually making a mess of things. About the only way these rods can be bent like that is by Hydro-locking the motor with fuel- which can be accomplished with an overflowing carb, or a stuck injector, or just simply not keeping the water out of the intakes while pressure washing. (see this on hydro locking here) So the big cross section on the beam of the new Carillo's should do much to eliminate that, while not being so heavy as to kill the bearings. We will soon offer these rods as an option on builds and rebuilds and consider this a good form of insurance. And as with much of this sort of thing, these may seem easy to "throw some in"- but installing them correctly is another, much more technical matter.


3) '99 to '05 Yamaha R6 or R6s oil pan mod-
We have used the stock '02 type R6 oil pan and pickup from the start with the R6's and have had the 'don't fix it if it ain't broke" mentality about this vital part of the motor. We have seen many billet designs that were not thought out very well as to oil flow, plus being very expensive. So we came up with a new, very affordable mod that retains the rigidity of the stock pan while utilizing a 6061 sheet bottom for increased toughness, more oil capacity and a bit more ground clearance. One advantage of this pan is you can install it yourself without even removing the pickup.

4)* rules were changed again for 2013....leaving us with custom oversize pistons including some +3mm Gsxr sets that we will sell cheap- Pass it on to any bike guys or anybody wanting wanting to build a motor bigger than 640cc....
640cc + "Monster Motors"-
With some racing organizations now allowing motors bigger than 640cc we now offer that as an option. We don't care for the rule, but you have to race within the rules you have- not the rules you wish you had. The details of the "how it's done" become even more important on large cc motors. Plus big cc's without adequate "breathing" is a waste. You can trust us to get it right.
Common sizes are 655cc, 688cc, and 700cc

July 2012: Mike Hudson's Powri Honda recently made 152hp and 63.5 lbs of Torque at Stewarts Dyno Service!
It's a brute! If you just have to have the baddest motor in the land
then you know who to call!



Update August 25, 2012: We are very close to getting our new axle-hub/chassis dyno completely dialed in... it's working awesome!
A big thanks goes out to the outstanding tech guys at Land & Sea for their excellant product support...... These guys are the top rung on the "dyno" ladder.

5) New Chassis 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.. and still much more to do and make such as engine stands, etc
Yep.... soon you will be able to get your car tuned by guys 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.
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 plan to do extensive in-house testing with various fuel injection systems in the weeks ahead. We have always maintained that we have yet to see a proven significant power increase over our our carburetors with any injection system to be worth the cost and complication. Note: I said "our" carbs- don't buy into some guy telling you some system made "X" amount of horsepower over quote "carbs" ... Heck, "our" carbs have been doing that over the "other" carbs for years!
But with that said, we also try to keep open mind, and so if we see something we like in our test sessions we will let you all know right away. But for now, our recommendations are to stick with what has proven to work and what has proven to win for many years: FTZ carbs and air filters.
Check back often for more new stuff coming online.

Announcing! The biggest advance in 600cc Microsprint engine reliability!
The FTZ Oil Cooler Kit-
This is a life saver for your engine!
This uses the latest in hi-tech water/oil intercoolers 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

NEW for 2012! FTZ Engine Pre-Oiler
Here is another good idea for you. We have designed this engine pre-oiler to allow you to push oil all through your motor before you ever crank it over. This device will pre-fill your main oil galley, the oil filter, prime the oil pump, fill the oil cooler and any lines or passageways, and even push oil all the way up to the cams. To be used after any engine swap or even after an oil change!
It is well documented that most engine wear happens during startup--so here is your solution to longer engine life and more races between rebuilds..... We do a lot of rebuilds and the best looking used bearings we have seen lately had twice the races as normal on it and so happens that the guy has rigged up something similar to this.
It hooks up to one of our standard oil galley plugs- same as a oil pressure gauge uses. You can use a tire air chuck to push the oil all through your motor in seconds, Too easy!!
This will work on any 4 Stroke motor that you can put in a access point to a oil passageway.
Let us know if this sounds good to you, as we will start production soon.....

*some limited sponsorships available. email to ftzracing@gmail.com or via GMail

Get with us about building your '06 to '12 Yamaha R6 motor:
These black motors are getting more and more popular. They have good high rpm capability making for a wide powerband. We can build these as 600cc, 636cc or bigger. Anything from stock class to full outlaw, mild to wild. Let us put a package together that fits your needs. They have been used with both carbs and injection both with good results.

We have a FTZ exhaust system specially designed for this model motor and also provide harness mods for converting to carburetors. (See more below)

We have also recently built some Suzuki GSXR motors with very good results as well. They are quite similar to these later Yamaha's, with titanium valves, etc.
There is lots of variety going on around here these days!

08 R6 carbs

Hot!!: for the 2006-'07 R6's. And now for the 2008-'12 models as well.
We have perfected a wiring harness mod for eliminating the tricky throttle-by-wire system on these models, allowing you total freedom to use carburetors with an optimized ignition system!
No laptop, no expensive dyno tuning, just plug & play for top power!
Call for details............
We offer ignition conversion kits (now in stock) for the '03-'05 injected R6's- Utilizing the '99-'02 type harness, engine cover and modified "hot box" to eliminate the complicated stock harness and all sensors.

We have stepped up our program on all wiring harness mods,
using armored sheathing and shrink tube to ensure that you don't have any problems at the track and a first class appearance. A huge step above the average taped harness modification.

'06-'12 Yamaha R6 Oil Pan Mod- With an improved oil pump pickup system- Better oil delivery and filtering to protect the crank & rod bearings from damage. We can update your previously modified pan to use this better pickup system. Only trust the 600 experts for these important modifications.

New FTZ Exhaust: We have developed a special Exhaust System especially tuned for the 2006-2011 Yamaha R6 motors- Call for details

Ask us about our new fuel delivery system!
Using the Mychron data system to study data during a race, we are able to see real-time changes in aspects like air/fuel ratio and fuel pressure. This has led us to rethink the fuel delivery systems. We have been testing with a new higher pressure in-line pump and special bypass regulator which is arranged to deliver more consistent and even pressure at the carb. A "must have" for FCR carbs that really drink fuel quickly with their accelerator pumps.
don't think that your system is as good- it's not, but you just not aware of how much your pressure spikes and drops during a race- and the negative effect on power it is causing. Call in for more details.

*R6 Motor Mount Mod- We have came up with a neat little mod to reinforce the right front tab used by many chassis companies to mount the motor. This tab was never intended as a motor mount, it only holds the fairing on the bike, and they come in broken all the time. We machine off the tab, and expertly weld on a hefty replacement that we CNC machine from billet to make it many times stronger. Request this done on your motor- when bought new or rebuilt.
Only $65 ......Also a similar one can be done for the left side as well.

*R6 Carb Alcohol conversion- NOW FOR '06-'09 Yam R6's and '07-'08 Honda 600RR's!!
Our Yamaha R6 alcohol conversion has proven to be the fast way to go. We are getting calls from many guys that have replaced their previous carbs with FTZ modified carbs, and are feeling a big power gain- especially when combined with the FTZ exhaust!
Now also for the injected Kawasaki 636, Honda 600RR. as well as the later model R6's including the '06-'07 models.
Forget that laptop and those fuel injection tuning troubles! .....$250

Option since July'06: Call about the latest Air Correction Jet Option- Allows you to make mixture tuning changes easily and better power! Ditto for our new Billet Velocity Stacks! These are just 2 more reasons why our carbs make more power!

New:** Hi-Rpm Velocity Stacks for the Yamaha R6 carbs- We have made these trick velocity stacks for the original '99-'02 R6 carbs. They where used to record our best dyno tests ever. When they were first put on a set of carbs, it made 3 more hp on the very next pull! These are the best hp gain for the buck you will find!
Made from aircraft aluminum on our in-house CNC machines. ..................................$200 set of 4.

** FTZ Level-2 R6 Porting & Head Mods
This headwork will help your motor, regardless who built it.
Also for other makes and models.
Also ask about our overbored R6 motors. Get the most out your rules for 618cc or 636cc!
The best just got better!
These mods allowed us to produce as much as 10 more HP than without. Nobody else offers anything closeto the craftsmanship that goes into this awesome modification. 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.
This headwork combined with our high compression mods is like getting a 2mm overbore!
No other builder's "port job" even comes close.....................$1500 + valves & seals.
Cam timing, sprocket slotting, and shimming extra.

Base Level Motor:
We are now offering an "Base Level" Outlaw 600 R6 Engine and also as a "Car Kit" Engine Package-
For the competitive minded 600 Outlaw MicroSprint racer that wants a FTZ built motor- but can't justify the cost of a full blown package with all the extra bells and whistles. No one really wants to go out there with a stock motor and have the guys with built motors pull away leaving you back in the pack bashing it out with all the back markers! This is a good motor to "build on" or upgrade later if you wish. This package uses our Level1 portwork/head mods with our custom oversize valves, a full bottom-end rebuild, and all our internal engine mods for improving reliability including updated transmission gears and a new oil pump with our exclusive oiling system mods and oil drain relocated.
The motor/engine unit itself starts at only $4495 outright.
*If you are trying to compete with fuel injection on a R6 motor, contact us for a quote on an injected model R6 built motor... Carbs or injection, a built motor is much better!
The "Base Level" Car Kit package: This includes most everything you need to outfit a new car. Includes the above motor in a package with FTZ modified carbs w/air correction mods and jet kit, FTZ air filters, FTZ Exhaust system, full electrics and ignition system with modified harness. Ready to bolt in your car. All for under $5900.
*We feel this engine package is still more than competitive with any of our competitor's best built motors!, and also more reliable than even a bone stock motor...
So why run a stocker in anything but a stock class?

*These motors are very low maintenance, and most "during-season" service work such as checking valve clearances,etc. can be done yourself, or by any qualified motorcycle mechanic.

Just call and ask about the "Base Level" Outlaw 600 motor for more details!
See Level2 details below for "All out" motor and packages

**2006-12 Yamaha R6 work- We can go through your '06-'12 model R6r with a total rebuild, portwork & trick valve job, oil pan conversion, exhaust, Ignition upgrade and even a tricked out set of R6 carbs or FCR flatslides! Get the most out of your '06-up R6!

New & Hot!!: for the '06-'12 R6's. We have perfected a wiring harness mod for eliminating the tricky throttle-by-wire system on these models, allowing you total freedom to use carburetors with an optimized ignition system! Call for details............

from 2007: *We have dyno tested, and more recently track tested the 2006-07 YAMAHA R6 motor, with quite good results. By eliminating the complicated throttle-by-wire injection and using our best alcohol carbs, exhaust and ignition combinations, we feel that we have a very good affordable package to offer for the stock classes, the budget minded Outlaw racer, or as a good alternative for the Pennsylvania area tracks. . Although power output was still down a good bit from our fully built Outlaw R6's, it is quite good for a un-ported motor. This is proving to be be a good, easy to maintain power combination that is out there winning races. Contact us for more details!

*We are again offering alcohol carburetor conversion kits for the late model Kawasaki 636 motors. Better power, much less complication and much cheaper than fuel injection. Call for more info!

This is a 20,000 rpm Digital tachometer that will accurately read the engines rpm's. It also has the maximum rpm recall feature, so you can see what the max rpm was after the race. This is a "must" for anyone using a "Hot Box" or modified ignition ECU.
This can save your motor


Also: Can be used as an oil temp gauge!!
Just put the sending unit in the oil galley.
Oil too cool?= Boom! Oil too hot?= Boom!
Just think about what that might save you!!
We now have an easy-to-read, matching water temp gauge to match the Daytona tachometer. Can be wired 12 volt or ran from its internal battery. Aside from being very lightweight and compact, a real advantage is the small easy to install sender is able to be fit directly into the cylinder head- where it belongs- not in the waterneck or hose or radiator, giving a much more accurate reading.
This can also save your motor...............$99.95

** FTZ Timing Advancer Rotor- for '99-'02 R6 motors with "Hot Box" ECU.  
This is a rotor we designed especially for R6's using the Modified stock ECU or "Hot Box". This rotor will advance the timing to the exact specs that made the best power in our dyno testing. Expect better throttle response and better starts with this rotor as well as an overall power increase. Will work with '03-'05 R6's with the '99- '02 cover & trigger, harness . Not legal in some of the stock classes.
FTZ R6 timing rotor............. $55

* * FTZ Big Track exhaust Collector-
This collector will add 2-3hp to the power above 9000 rpm and fits all our pipes since 2004. A moderate flat spot similar to other brands of pipes is in the 7000-8000 rpm range, so this is not for small one lane race tracks where you have to slow way down for traffic.................$169.95 bare, $189.95 coated.

**35mm FCR Keihen Flat-Slide Racing Carburetors for Yamaha R6-

We have perfected these top notch aftermarket carbs for the alcohol 600 Micro's.
