Dyno Tuning

Coming to the Sturgis Rally / Black Hills Rally?

With our state of the art Dynojet Dyno model 250i, we are able to Tune, Diagnose, and Fix almost any running issues your motorcycle may have, whether it’s carbureted or fuel injected. Here are some commonly asked questions and answers about Dyno tuning.

Why should I have my bike Dyno tuned?

Dynotuning isn't just for measuring Horsepower and Torque, it gives our factory trained dyno technician the ability to map and adjust fuel levels at any rpm and throttle position. We all know that performance upgrades are not cheap! With that said, what if I told you that you weren’t getting the most out of those upgrades.

Can Dyno tuning improve fuel mileage?

YES! Even on a stock bike you may notice that you’re not getting as many MPG’s as your friend who has the same exact bike. This is because every bike runs differently, yet they all come with the same factory set map. Dynotuning can greatly increase fuel mileage in this case. Another common issue is after installing a set of exhaust or other performance upgrade. Many people say “that’s normal”, however, you should not notice a great decrease in fuel mileage, if you do, it’s normally because of either not being tuned, or having a bad tune. We’ve seen gains of as much as 20MPG’s with just a quick and easy dynotune.

Are all “Dynos” the same?

Absolutely not! Please be advised that many shops are currently using old or outdated equipment and software that are just not suited to do the job correctly. Here at Dakota V-Twin we house a state of the art Dynojet Dynamometer model 250i with load capabilities, an air/fuel ratio “EGA” machine, using Winpep7, and always being connected through Tuning Link, which is a very necessary program that still today, most tuning centers do not have.
