Ah, but my quest wouldn't end there. As some of you might remember from the last issue ("Out to Launch") I'd already committed to a grudge match at the AMA ProStar World Finals in Gainesville, Florida against Speedvision commentator Larry Maiers. My plan for the Mean Streak was to see how far it could stretch. After the VROC rally, the bike would be shipped to the Thunder shop in Phoenix, Arizona, where it would be torn down and given a Stage 2 treatment. This kit would retain the existing mods but add to the recipe a port-and-polish, bigger pistons, larger throttle bodies and more assertive cams. I wanted at least 100 ponies out of this bike before I ticked the light tree.

It came quickly this time, the peace. I rode until 2am and clarity was already taking hold. Everything in my life makes sense looking in from out there, and I understand my place on the planet. At the first sign of weight in my eyelids I checked into an ambiguous Best Western just over the Arizona border and slept more soundly than I had in months. I'd started out from the office with a new gel butt pad on the bike--a product I'd been meaning to test, but discarded it after a couple hours (it felt like frozen pizza) and found the stock seat exceedingly comfortable for long stints. I would clock 1100 miles the next day to prove it. In fact, I wasn't uncomfortable at all on the crazy-fast trip and the small accessory windshield offered just the right amount of wind protection without mucking up the lines of the bike.

My average-size soft luggage was easily adapted even though there are no appointed hooks. (I used the rear peg brackets and taillight stems.) Happily there is lots of space between the fender, rear brake caliper and the pipes. I had only troubles when I rode the VTX cross-country with the same luggage. You do have to carry bags high on all these bikes though, since the small rear fenders want to suck saddlebags toward the wheel. I was also riding the Mean Streak with a magnetic tank bag and the clean, broad tank made a perfect mount. The beautifully styled tank only holds 4.5 gallons of fuel (one-half gallon less than the Vulcan Classic FI) but more efficient injection and overall lighter weight actually provide a longer range. I could easily ride 145-mile stints before stopping, and I was riding hard.

On my final day I woke up late and spent some time hunting film and spray paint before heading out to the Cadillac Ranch. I wanted to photograph the Mean Streak amidst the colorful, upended relics but it required sneaking through a people-sized gate on the edge of the field. The Mean Streak's front end went in okay, one end of the bar at a time. But just when I thought I was in like Flynn my soft luggage wedged. So much for stealth. Since I couldn't put the kickstand down, I had to wrangle the saddlebags off by sitting backward on the bike. I then shot through the gate like a cork, followed by a stream of bemused tourists. I chuckled over the scene many times during the last leg of the ride from the Texas Panhandle to Arkansas.

Eighteen miles short of my destination I was pulled over by a battalion of Arkansas lawmen. The four Sheriffs and one State Trooper that surrounded my bike were definitely impressed that I'd ridden from California in less than two days, but gave me a whopper of a ticket anyway. They didn't buy my story about how cops in my home state use a combination of colored lights, not just little blue ones when they wanted you to stop. Before escorting me on, they told me to be extra careful on the "crooked roads" ahead and I thought that was pretty darn funny until I passed a sign a few miles later that said "Crooked Road Ahead."

I'd talked to my boss over the howling winds of Oklahoma earlier that day and he asked me how it was going. I said, "Fine, except I'm almost there." It wasn't that I was sorry to be at the VROC rally (something I'd looked forward to for months) or that I was in this incredibly charming and historic town (I'd spend the next couple days fantasizing about moving there). It was falling out of the spell of the road that saddened me--the dimming of lucidity and the return to the restlessness I feel in everyday life.

This didn't take long either and I was impressed not only with the simplicity of applying the Stage 1 kit but also the affordability (about $570 without the pipe). You end up with a nice looking air filter cover as the only external change (save the exhaust, which is necessary for optimum results). The small Power Commander module is hidden behind the left sidecover. I have come to think of this as Everyman's Hop-Up: Something immediately gratifying that doesn't tamper with the engine internals.

The Mean Streak's change in output was obvious the next time I left the parking lot. "Here you go," I thought as I tore off into the Arkansas countryside. "Now you're sitting pretty among performance cruisers and you still cost less than the others do stock."

I announced at dinner that I was looking for someone to ride with the next day and the Dallas Fort Worth Chapter was quick to take me under its wing. I was even more excited that this particular group of men and women was well known for their skill and appetite for fast corners. We had a ball, albeit a chilly one. Yes, this sharpened Mean Streak was even more fun to ride, and yes, I totally recommend the upgrade (although I personally would shop for a quieter pipe).

I flew out to Thunder's fast-growing facility the afternoon the engine was to be reassembled. In a little over three hours Dave Rollins and his sons Travis and Trent slipped the new pistons into the slightly expanded sleeves, applied the cams and throttle bodies then buttoned up the cases. There was something very intense about watching that huge motor being brought into the gaping hole in the Mean Streak's frame. Less than an hour later the bike was running and ready for the dyno.

On the first graph, horsepower at the rear wheel was peaking in the 90s, we'd all been hoping for a triple digit. It wasn't until the next day when the motor had cooled and injection had been fully dialed that it hit the mark. The bike was packed for the races running 100.6 hp and 105 foot-pounds of torque. Thunder had produced an identical Mean Streak for my opponent Larry Maiers to ride. The rest was up to me.

Both of us took advantage of the test and tune day at the Gainesville Speedway the Thursday before the races began, making as many runs as possible so we could hone our methods. Except for a blast down a busy street in Phoenix the night the motor was first installed, this was the first time I'd ridden the improved Mean Streak. And yes sir, it pulled like a bull. An air shifter fitted at the track was controlled by the horn button--definitely a nicety since my optimum launch rpm was about 4500 rpm and I'd shift just under the limiter at about 5800, which left little time to reel in the old clodhoppers. I was pleased with my end-of-the-day runs (low 12s) and left the track feeling pretty confident.

Waiting in line for an hour to get a 12-second thrill isn't very exciting. Or that's what I'd think while I was sitting there. Then I'd move close enough to breathe the smoking rubber and my heart would pound and I'd think, man, I can't take this drag racing--it's just too intense. And finally, each time I'd tick that quarter-mile beam all I could think was I needed to be back in line so I could do it all over again.

I hadn't lost in Street ET yet, but I choked in my race early Sunday morning, which I supposed was best, since it gave me more time to psyche out White before our grudge match. We knew we wouldn't go far in the actual Hot Rod Cruiser class because as quick as our Vulcans were, they weren't up to the 10-second quarter-miles the pro bikes were running. But then again, I wouldn't get on one of those bikes that had been stretched with extreme mods and ride it back to California either. The Mean Streak felt as solid as it ever had and I trusted it just as much.

White and I had both grown fond of waiting in line with the Hot Rod Cruiser riders though. We were few, but we were fun. In all my days of covering races I've never witnessed such a jovial attitude between competitors. When it finally came time for the big showdown, the group insisted we go first so they wouldn't miss it. A pat or two on the back and we were moving toward the burnout box.

When people say, "This is the moment I've been waiting for" they generally aren't talking about something that will last precisely one moment. But here it was. Everything slowed down when I was finally facing down the track and dumping the clutch for that big tire spin. I pulled out of the burnout and took a deep breath. Out of the corner of my eye I could see White jabbing a WWF-style finger my way, but it didn't break my concentration. After heating the tire I did a little practice launch to see how well it hooked up before moving into the groove and inching up to the first beam. The first trigger will light the top staging bulb on the tree, and this is where I typically stop breathing. I pressed myself against the tank, brought the revs up and waited for White to stage. We were running a pro light in this class, so instead of a three-light countdown there was only one full flash before green.
