Doin' just fine in 2009!

Dyno Testing All Motorcycles
Expert Tuning American V-Twins


V-Rod under Lexan -- NOW 132 HP @ 8000 RPM. Update 3/7/2005, 140 HP!

Dr. Dyno specializes in "Feel the Difference" therapy for Harley-Davidson motorcycles.

In need for a motorbike dyno? Dr. Dyno tests all motorcycles, from Panheads to V-Rods and Sport Bikes, strictly within the owner's constraints. The rpm and speed YOU ride is where the power counts.

Why pay someone else for an "improvement" that's only on a printout when Dr. Dyno wants to read it by the grin on your face? About half of the V-Twins out there are running 10% to 50% below their potential at the speeds they're being ridden. Every bike is different. Every rider is different. Dr. Dyno takes tuning one step further than the "Mr. Dynos," he moves the power band of YOUR BIKE to where YOU RIDE. That's tuning the bike to the rider and that's the Dr. Dyno difference!

Here are the four areas the doctor uses to make you "Feel the Difference."

  1. Air - Assemble and install non-restrictive high flow air cleaners.
  2. Fuel - Right-jetting carburetor or Proper-programming PowerCommander, TFI/DFO or Race Tuner.
  3. Ignition - "Sweet Spot" timing. For best power and economy, timing is everything.
  4. Exhaust - TorqueTuning pipes to cam timing by adding or reducing backpressure to put the power where YOU want it.

To those who say you need to jet your carburetor for your pipes I ask, "For what: midrange power or top end?" You won't get both. Conversely, simply tuning the air/fuel ratio on fuel injected Harleys doesn't necessarily result in best midrange power.

Dr. Dyno hit the pages of American Iron Magazine again in 2006 with some well received articles!

The May issue is an updated reprint of the first "Dyno Dos and Dont's" from April 2003.
The June article details proper dynotuning of carbureted Harleys, including TorqueTuning.
In July I explained why dynos read differently - some reasons legitimate, others purposely faked.
The August article covers the H-D Race Fueler, Dobeck Performance TFI,
Custom Chrome DFO and Kuryakyn Wild Things FI controller.
The September article details map-based EFI tuning options.

Your feedback or comment is almost always welcome.
