Craziest Thing I Ever Did ...
(at a racetrack)
The World's First:
After the event you're about to read about took place, this engine was
re-assembled exactly as is it was (it was not freshened up, nor were any
parts replaced). The motorcycle was then sold to a new (2nd) owner, who
raced it for about 1 year. Then the next season it was sold to yet another
(3rd) owner. The same engine was used all the while, and it had not been
rebuilt or taken apart since the teardown shown in these photos. Here are
2 e-mails I received from the 3rd owner, well after this article was
My name is Brad Hochhalter. Just last week I purchased Gordon Good's '98 ZX-6R w/ that wonderful Mototune engine in it. I used it to great
success and with much envy from the other riders in my OMRRA novice class at PIR last weekend. I am still amazed at the number of comments I got from
other riders about how hard this engine pulls past them at the end of the straights. This thing is better than the Duracel bunny on the
straights...It just keeps going and going and going right past everyone.
WOW! You guys really did an amazing job building that thing.

Then About 1 Month Later:
Moto Man, I thought I might share another
Mototune victory with you. I took 1st overall in the afternoon OMRRA novice race at PIR on June 11th. I've included a
pic of me passing
an R1 and a ??? moving into the lead at the end of lap 3 (of 7) thru turn 9 at
PIR. Wet race but loads of fun. Love the power.

Here's The Story Behind This
Remarkable Machine ...
All Started While ...
was tuning for Dave Cook at Portland raceway in the spring of 1998 when a Canadian
racer came up and asked:
I hire you to build my Zed-X-6 motor, will
you do as good a job on it as you did on Cook's ? "
the motor was built, lots of people were noticing
Schmidt's sudden rise to
... and some started wondering if maybe the motor had some major
illegal work done to it to make it so fast.
The last race of '99 was a big win for the
"the last OMMRA 600 supersport race of
the millennium", Alan began taking the bodywork off
his bike, while I
went up to the
I asked them to announce over the P A system
that we'd be voluntarily taking Alan's engine apart for
by the beer counter and everyone should come over and get a beer and watch!
We thought it would be a cool way to end the season. Everyone would
soon find out that Mototune is the real deal... plus Schmidtastic could be proud of what
he worked so hard for !
Normally a "teardown"
involves a "legality protest". The competitor(s) questioning said
legality must put up about $300-$500.
If the protestee is found legal , he keeps
the money to cover the cost of gaskets and headaches associated with having a
bike in a million pieces before the long drive home. If he's cheating, the money
is returned to the protestor(s) and the guilty party has to drive home in shame!
Here's How It Happened...

(It was noticed by an observant reader of this page !!)
The pistons are very scuffed, and apparently not sealing very well.

How could this bike have been fast when it looks like it's leaking ....
what has happened here ??
The First of The Secrets
Can Now Be Revealed ...
Some of the very early 1998 ZX6R models had too tight piston to cylinder
clearance, and no amount of running-in would correct this problem. I first
worked on this engine after it had been raced for several weekends, and
the damage was already done. Since this was at the beginning of the racing
season, Schmidtastic would have missed races waiting for new pistons.
Friction was clearly robbing this engine of power, so my solution was to
hone the cylinders to correct the clearance and to remove the cylinder
scoring which was causing the leakage. In retrospect, I think I honed the
cylinders a bit too large, but it worked really well. The pistons are
heavily scored, but with new rings, and a freshly honed cylinder surface,
the cylinder seal was restored to near perfect. For the rest of '98 and
all of '99 the same ugly scuffed up pistons stayed in the motor
for thousands of racing miles, and lots of race wins !!

middle of it all this guy came up to me and said:
the Mototune team really puts on a
cool show for the Fans! "
How did we
make the ZX6R so incredibly fast that everyone was 100% sure
that we were using big pistons or racing cams or head porting or
a lightened crank or higher compression or illegal metal removal
or race kit parts or maybe even all of these things ???
