It probably started a few years ago. One of those recurring conversations where you talk about something you ought to
do sometime, but usually never end up doing it. On several of these occasions, the subject was about me riding the
Cambridge TT. One of my father-in-laws is a long time member of the Norseman Motorcycle Club, the club that promotes
the Cambridge TT. He raced dirt track back in the day and his main reason for being in the club, and the event that
gets his most attention, is the TT. When the subject came up, I was usually the one suggesting that I ride it, which
was then followed by a look of concerned skepticism on my wife’s face, then a change of conversation topic.
Except for some trail riding when I was starting out, I’ve been a motocross guy and nothing else. I’m interested in
and read about almost any form of competition that features two wheels and a motor, but the only one I’ve actually
done is motocross. This year, I decided to finally try some of the other forms of competition that were out there.
I’m not exactly setting the world on fire at motocross, so competing in something I didn’t do too well at would not
really be that big of a change. My low budget approach would be to make the minimum amount of modifications to my
2003 YZ 250 to make it competitive, or at least legal, for the type of competition I was trying.
The Cambridge TT was the natural choice for Dirt Track, and since it was scheduled fairly early in the season,
it would be the first other venue that I would attempt. My first step was to find out what I needed to do to the
bike and what classes I was eligible to enter. I contacted the District 23 Dirt Track Rider Rep, Rick Waschek. He
told me that the knobby on the front would be fine, but with a knobby rear tire, I could only run the Knobby and
Beginner class. If I had a dirt track tire on the back, I could then run another four classes.
Rick generously offered to let me use one of his partially worn, nineteen inch dirt track tires. After revealing my
rather embarrassing inability to change tires, he even mounted it for me. I set the front to 15 PSI and the rear to
18. The other changes I made, at his recommendation, were to soften the compression damping and stiffen the rebound
on both ends. The soft compression helps it settle down into the travel sooner and the stiff rebound helps to prevent
highsides. The other no cost things I could have done would have been to raise the forks in the triple clamps, reduce
the preload on the shock spring, pull the bars back and move the levers down. I decided not to do any of those things
and see how it felt in practice. If this had been an oval race, I would have been required to remove my front brake lever.
