The History of Best Dual Sport Bikes

At the age of 10, with a Honda Z 50 that wouldn't start the second time, after the spark plug was replaced, it took a young determined kid 1 year to figure it out.
 

Self taught, with nothing but books, service manuals and magazines, it took 1 year to figure out that the spark plugs heat range was one size to cold.
 

At age 11, came the first learning experience to stick with it and not give up.  As the bike started the 2nd and 3rd and 4th time, a 11 year boy cried tears of happiness, knowing his life may never be the same.
 

As the boy cried, so did his mother.  If it didn't start, she didn't have to worry. She also knew that her life may never be the same.

​At age 16, it was apparent that I was better at fixing things and figuring out how to make them run better, than being a racer.  I was a good rider, but not a racer.  Also apparent was racers spent money on guys like me who could make things better. My first business venture , DS racing was born.
 

A junior in high school in 1984, there were many weeks I'd make $400 - $600 a week part time fixing things in my parents shed.

Went to MMI 6 weeks after high school.  Met 2 great instructors there and we decided to go into business together when I got out.

Advanced tek needs was born. I didn't own it, that was one of the MMI instructors. We bought all the crankshaft stroking equipment from Helm and Son ATC and started stroking jet ski crankshafts.
 

I learned all about cranks and metallurgy and welding and machining from a spectacular and highly intelligent individual, named Marv Wacendorf.
         

At 18 years old,  I'd get up at 5 in the morning, go stroke 5 cranks and build them until noon, and then head out to the Arizona lakes to test. I was doing cranks for champions like Larry Rippenkroeger and champs all over the world.
 

I was also stroking cranks for Damon Bradshaws YZ 125, even though he had no idea. That was between Bobby Barr of Barr's competition and I.

Started Arizona Engine Fabrication and went out on my own building Jet Skis.  Made some of the fastest skis at the time.

Wrote first book, called "The Jet Ski Bible."

Had 5 skis that won world and national championships. Built skis for the prince of Dubai and invented the SST technology, which would later become the FMF 2 stroke pipe

Wrote 2nd book, called "2 stroke technology".

 Had race parts in most top jet skis at the World Jet Ski finals and in many countries.

Sold business and went off to school, on a bio mechanical scholarship. Trained Olympic athletes at NAU, on their way to the Atlanta summer Olympics. Invented "the wedge" while training the Japanese women's swim team.

The wedge took off and I quit school, due to taking care of elderly family.  The wedge was a good money maker, but I only thought about engines and making them faster. So I went back to mechanical stuff.

Moved to England to get back into Jet ski development and learn about intake tract design from a Williams Renault Formula one development firm.
 

Invented a new form of throttle body. It was documented to work well enough that it made the front cover of Eureka magazine in January 1999.  Eureka is the UK's version of Popular Science. This grabbed the attention of Yamaha racing, who contacted me for development.

Yamahas interest in my intake design, led to me making parts for their new road race bikes, which were fuel injected.   This lead to working with a Yamaha Pilot shop, called Mission Valley Yamaha.
 

This lead to going to FMF to do some dyno testing and Meeting Don Elmer at FMF, leed to the making of the first SST pipe that day.  Gaining a full hp on the YZ125's or the Yamaha of Troy team's bike at the time. 

Donnie asked me if I had any other ideas. That started the development relationship with FMF. It also started the relationship with Tom Webb and Dirt Bike.

In 1999, I came up with the "Power Bomb" for the 4 stroke headers, The " Power Now" carburetor insert and the SST 2 stroke pipe. The SST stood for Simon Sonic Technology.  This was named by Tom Webb. I also started doing part of the "Mr. Know it All" column in DBM.

Was involved with all bikes and teams and development pretty much.   Developed pipes for 2 and 4 strokes for YOT, Factory Yamaha, and Factory Suzuki.  Tested and rode and learned a lot.

So much going on at this point it's hard to remember it all. Working with factory Kawasaki now.  had the first FMF 2 stroke pipe on Ezra Lusks bike at the first Glen Helen national.  First time some else other that pro Circuit was on a KX.   That says something about how well development was going.
 

I had all the KX's and parts and any bikes I wanted.  I had factory magnesium carbs I was gutting up to try and make better. It was great.
 

Donnie and I started " Scary Fast Racing", to get the Power Now carb splitter out there. It became product of the year twice and quickly got endorsed by Malcolm Smith, randy Hawkins, Suzuki and some
KTM teams.

Also in 2003, I came up with the "Mega Bomb". Just a larger chamber than the Power Bomb. Laughed at, at the time, it's now standard on all MC head pipes.   So people who laugh at my ideas now, I just laugh back at the stupid turds, knowing they will be buying it in a few years.

Worked for CARB actually, at night, after my day stints in Ca.  I was the guy who did the carb testing to verify if a bike passed compliance or not, and could be sold.  Leaned a lot about what it really takes to pass and things that affect emissions outputs.

Worked a lot with the main USFS office in San Dimas, Ca.  On noise and what it took to pass a spark test.

Lots of travel and living in various countries.  Working with various factory teams on lots of things and learning a lot about what really works. Also what works on one bike doesn't work on another, so never quit trying new and old things, on every model.

BDSB starts as a side project, so that FMF can sell pipes and Dirt Bike magazine can give the new KTM EXCF"S edit.
 

The bikes were so lean at 1/3 throttle, that when you changed the muffler, it would hardly run.  Donnie didn't know what to do, as everything was so new, that now one had anything to make them richer with the fuel.   Knowing what I knew from working with Keihin, I just cranked the TPS up on the throttle body and manipulated the MAP sensor input and it worked. It ran great. And that was the modification known as the "magic mod"
 

Tom had the idea for me to start a side deal, to do the magic mod, and then we could promote the pipes and mod in the mag.  The first article on hopping up a 2012 KTM 500 EXCF came out in DB that year, with yours truly riding the bike in the pics.  That article helped get adventure mirror, seat concepts and shorai batteries going as well.

BDSB became so successful, that the income from that surpassed all my checks from all the other entities combined.  And with that I quit traveling to California unless needed, and stayed in Arizona.

Moved to Sequim, Wa.  Retired but work harder than ever because it's fun, I love making peoples riding experience better and have lots of ideas. Started Pin-It racing, to work with bikes that don't just have headlights and to make parts for others as well.
