Dyno services

When you first purchased your new motorcycle, your engine's computer is already tuned to work with the components that came with it. It's was factory perfect.. Right out of the box on Christmas morning. But when you begin modifications and upgrades, such as pipes or air cleaners your engine is no longer optimized; the computer map is no longer calibrated to the upgrades on your bike, and you need a new map to balance it out. This is what dyno testing is all about. If your motorcycle has a new exhaust system, high-performance air filter, or other more exotic engine modifications, you will greatly benefit from having fuel delivery and ignition timing that matches the engine's new characteristics.

So if you're ready... Really ready, then come see us at Harley-Davidson® of Washington, DC

Laurence 'Beul' Beulah Performance Specialist & Expert Turner Engine Builder

With over 35 years of repair and building with Harley-Davidson® and countless hours perfecting the Dyno tuning process, Beul is #1 in the field.

Specializing in high performance engines and customization he can optimize and tune your bike to its peak of efficiency and power.

Laurence BEUL Beulah, our resident performance expert employs the most cutting-edge technology available to do just that. By measuring torque, horsepower, engine RPM and the air/fuel ratio for your motorcycle, BEUL creates custom air/fuel and ignition maps that will match your motorcycle's engine configuration. While many aftermarket electronic fuel injection (EFI) controllers come with a "base" fuel map for your year, make and model of bike, no two engines are alike, and power tuning with the engine under load on a dynamometer is the only way to ensure optimum performance. Dyno tuning your motorcycle will offer smoother running, better roll-on acceleration, more power and additional fuel economy Harley-Davidson® of Washington, DC specializes in tuning and modifying Dynojet's Vision, the Screamin' Eagle Super Tuner, Harley-Davidson® Race Tuner, Direct Link EFI Systems and Thundermax.

The Dynamometer

A Dynamometer or "dyno" for short, is a device for measuring force, torque, or power.

The Dynojet 250i continues the Dynojet tradition of providing a reliable, repeatable, consistent and easy to use chassis Dyno for a quick and accurate diagnosing of performance problems. HDDC we have a fully functioning Dynojet Model 250i Dynamometer at our disposal to meet all your tuning needs. Our Dyno has an Eddy Brake for placing a proper load on your motorcycle while tuning as well as an Air / Fuel Ratio Monitor for more accurate tuning. Located outside of our service department, you can watch your bike being dynode and talk about it after it is done. We encourage your involvement and want you to understand the art of the Dyno.
