the perfect motorcycle out there now,
because I'm riding the s-- out of them!
Hopefully I can win this championship.
I'm sure those guys (Wait and Bostrom)
will be in Las Vegas (at the AMA
National) the same weekend I'll be at
Loudon doing this series. I have the
points lead anyway, so third place is
great for that."

ThiS. was: the first NASB event in 1996 where ·we.ather a'ld
schedul" cooperated So that a reason!,ble !,mount of practice ·and
qualifying time could·be provided. The track was open for NASB
practice most of ThursdayJlnd· Friday, morning, and many NASB
. ·racers also entered· CCS everits for additional track time (and, in
some cases. contingency money).
NASB founder Roger ·Edmonson pointed out the unusual com·
.position of .entries for this event. Four of the six classes this
weekend had Harley·Davidson-powered machines competing in
them: Formula USA and American Sportbike plus lhe two exclu·
sively Harley·poWered classes, TwinSports and Buell lightning.
An even more surprising statistic was the fact that 40 percent of
the total entries for the weekend were Harley·powered machines.
oto Liberty's Masahiro Iizuka won his third International GP race in a row by a
huge 15-second margin despite facing a
seemingly much more competitive field
than he had at the previous race at
Brainerd.
The writing was on the wall from the
qualifying session Sunday morning
when Iizuka took pole with a 2:33.4, 0.7
second ahead of his teammate Marcello
Del Guidice. And the rest of the field?
Over four seconds a lap slower. Del
Guidice shadowed Iizuka off the start
but was forced to pit for a stop-and-go
penalty for jumping off the line early. It
didn't matter, though, as he quickly
made his way back into the runner-up
spot by lap four and would remain
there to the finish.
Running third for most of the race
was third-fastest qualifier Vicky Jackson-Bell, though she occupied the second spot briefly when Del Guidice was
forced to pit for his penalty. After a
nearly race-long battle for the fourth
spot, Chirs Ulrich finally prevailed over
Mike Himmelsbach, who rounded out
the top five.
After five rounds, lizuka maintains a
24-point lead over Jackson-Bell, 162-138.
Frank Pate is third with 95.
With the results of qualifying such as
they were, it was no surprise that two
laps after the start of the race Iizuka had
a 9.2-second lead over Jackson-Bell
What was surprising was that Moto
Liberty rider Del Giudice, who had been
obediently shadowing lizuka, suddenly
disappeared, only to reappear well
behind Jackson-Bell. The officials had
determined that Del Giudice had
jumped the start and had assessed a
stop-and-go penalty.
The penalty affected the race only
momentarily. Del Giudice quickly
caught and passed Jackson-Bell on lap
four and pulled clear, leaving JacksonBell alone in third. A short distance
behind her, Ulrich and Himmelsbach
were having a long tussle over fourth
which was finally resolved in Ulrich's
favor in the last half lap.
