Sound Emissions Sound test was performed using SAE J192 Standard test

The machine accelerates for 150 feet after 150 feet of constant speed

Sound measurement is taken 50 feet perpendicular to the path of travel.

Sound levels were found to be 76.9 dB, also a full throttle full speed pass performed, which produced a 81 dB sound reading

Conditions of the test dayTemperature: 19 Degrees FahrenheitWind: 0 M.P.H.Pressure: 30.23 inHg 2/27/2014

Isobutanol Conversion

Power Commander V• Allows for complete adjustment of fuel

table off of AFR readings

O2 Sensor• Reads air-fuel ratio (AFR)

Dynojet Autotune• Allows for AFR data logging while the

vehicle is being ridden (only when enabled)
