Dynamometer Model 250iX with state of the art custom industrail noise control sound room. Contact your Service Advisor at 918-622-1340!
A Dynamometer is essential to realizing the full potential of today's complicated fuel injected and carbureted motorcycles with performance modifications. This is the only tool that can accurately calibrate fuel and ignition maps or diagnose run/drivability issues in a controlled enviroment. Routte 66 Harley-Davidson® has Technicians that are trained to tune H-D® Super Tuner and have experience with many other aftermarket tuning devices.
Equipped with Real time Torque module/meter, real time O2 and Eddy current load control, our Dynamometers is a state of the art, computer controlled, Dynojet® 250iX. By simulating the best "seat-of-the-pants" road testing righ tin the shop, many drivability/run problems can be diagnosed in a fraction of the time.
