**Download the 2007/2008 FTZ 600 .pdf flyer here**

Winter '07-'08:
We are up-to-date with the new "universal" 600 rules for the PA area tracks. There is a good bit that can to improve power and reliability under these new rules. We have put two different packages together to offer for the 2008 season using either the 2006-2007 Yamaha R6 or the '03 to '05 Yamaha R6.
Please read on.........

'06-'07 R6: We have dyno tested, and 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! Under the new PA area rules the '06-'07 motors will have to remain 600cc, but we can get good power out of these because of the superior breathing of the stock head and the very high rpm limit with the stock box.

'03-'05 R6: We are allowed to build this motor to 636cc. With this long stroke design combined with the new mods that are legal this makes an excellant, torquey and very reliable option to the Kawasaki's. The new rules allow us to tweak this motor to much higher outout than a bone stocker.

*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!

There is always two ways to do something: So with the popularity of the 636 Kawasaki, we have developed a killer exhaust system, as well as a trick carburetor conversion for them. These two items work very well together, giving top-notch horsepower, with great torque, powerband, and most of all consistency! This combination runs great without all the complications, and expense of fuel injection, and much easier to fix a problem with. This consistency and reliability lets you concentrate on your chassis setups that make you fast. This is a good option if you are tired of chasing the fuel injected game and don't feel like you are getting the power you should be.

Those that race with "open" rules, should also see our Multi/Outlaw R6 page. I'll add more as time permits. Thanks!

With the popularity of the 600 class in the Northeast we have been often asked to come up with more power for these cars. You really don't know what you get with a motor from a salvage yard. Also, as new motors become more expensive and harder to find, many guys want their motor rebuilt or freshened up for next season. Many of the fastest 600 Racers in the Northeast have ran our 600 motors over the past years. Whatever engine you choose, we have developed an excellent stock carburetor setup and a special exhaust system to match. The results are a smooth easy-to-gear wide powerband, from low to high rpm, with great reliability.

If your track follows different rules, we suggest you contact your track tech official for exact details of what you can and can't do to the motors. Then call us for a specific quote for building your motor. You will not get a better motor built for your track, nor will a motor of this quality be built for much less.
