Frequently Asked Questions

Q:	Why dyno tune your bike?	A:	We use a state of the art Dynojet Model 250 dyno with load brake and wide band oxygen sniffer. What this equipment allows us to do is maximize your bikes state of tune for daily street driving conditions or optimal racetrack performance. We set your idle for easier starting and passing emissions. The load brake allows us to simulate highway driving conditions to tune your bike for maximum gas mileage and bottom end drivability (both carbureted and fuel injected). Then on to maximum horsepower and torque: Full throttle tuning for passing that motorhome down a two lane road or first to the checkered flag at the finish line. By setting your air/fuel ratios we can get all your bike has to offer in drivability AND horsepower.
Q:	Why is a custom map better than a map downloaded off of the internet?	A:	There are differences in each motorcycle, even between the same make and model side by side. Maps downloaded off the internet, or installed in a new piece of performance hardware are designed to get you close for your bikes modifications, but that doesn't take into consideration altitude, ambient temperature, humidity, location, or the differences between each bike. By setting the air/fuel ratio for your specific motorcycle, we can get all your bike has to offer in drivability AND horsepower.
Q:	Why does my air/fuel ratio as read on Brand X's dyno show my Dynojet map as lean?	A:	Positioning of the O2 sensor is key in accurate measurement of the air/fuel ratio from combustion. We sniff the exhaust deep inside the pipe as close to the exhaust valve as possible, where the sniffer is reading what is coming out of the motor, not sniffing air at the end of the exhaust pipe that has been contaminated by reverse pulses being sucked back into the pipe.
Q:	Will the dyno chew up my rear tire?	A:	No more than a ride on the street of the same mileage of an OEM type tire. *Race tires can wear prematurely and we recommend bringing your bike with a street tire for the dyno.
Q:	Will my bike get overheated on the dyno?	A:	No. We use two 2300 CFM fans moving air through the radiator or over the fins (air cooled) to keep a constant average riding temperature.
Q:	Can you tune carbureted motorcycles?	A:	Yes we can! Sportbikes, Harleys, pocketbikes... pretty much anything with two wheels. *Now we can tune your Mini-Sprint, Dwarf cars, and motorcycle powered sandrails as well!
Q:	Will my bike blow up after being on the dyno? A friend of mine got some dyno runs, then went out and did stand up wheelies and his motor blew!	A:	No! The dyno doesn't cause any bikes to blow up. If your bike is in good running condition with a reasonable state of tune your bike won't blow up. If your motor has been run out of oil, has 50,000 miles or any unseen internal conditions, then anything could happen on the street or the dyno.
Q:	Why do different dynos show different horsepower numbers?	A:	Every Dyno reads a little different, different brands read differently. Temperature, altitde, and humidity can all play a role as well as software differences from dyno to dyno. The only thing to really worry about is the A to B changes on the same bike, same dyno, same day.
