Disclaimers
Dynojet Research, Inc. (Dynojet) makes no representation or warranties with respect to the contents
hereof and specifically disclaims any implied warranties of merchantability for any particular purpose.
Dynojet reserves the right to revise this publication and to make changes from time to time in the
content hereof without obligation of Dynojet to notify any person of such revision or changes.
Dynojet is not responsible for false operation due to unexpected dynamometer operation such as may
be caused by static, software bugs, hardware failure, etc.
Dynojet is not responsible for damage resulting from improper installation of the dynamometer or
from improper service rendered to the dynamometer. Dynojet is not responsible for damage incurred
due to alteration of the dynamometer or components, use of unapproved parts, or abuse to the
dynamometer.
Do not connect or disconnect cables or components on the dynamometer with the power on.
Always wear protective clothing, ear protection, and eye protection (goggles, safety glasses) when
using and servicing the dynamometer.
Equipment Power Requirements
The dynamometer has specific power requirements and instructions that must be followed for proper
operation. Power requirements and installation can be found in Appendix B. Failure to follow these
instructions could result in personal injury or damage to the dynamometer. Connecting the
dynamometer to the incorrect voltage will void the dynamometer warranty. Installation may require
a licensed electrician.
Potentially Lethal Voltages
Components attached to and within the dynamometer operate with potentially lethal voltages. To
provide the greatest assurance of safety, the AC power cord(s) must be disconnected from the power
source before servicing electrical components or wiring. Disconnect all power cords before servicing
electrical components for the greatest assurance of safety.

WARNINGS
viii
Electrostatic Discharge Precautions
Electrostatic Discharge
Electrostatic Discharge (ESD), or static shock, can damage electronic components within the
dynamometer. The damage may occur at the time of an ESD occurrence, or the shock may degrade
the component, resulting in a premature component failure later. To avoid ESD damage, always
practice good ESD control precautions when servicing the dynamometer. Dynojet designs its
dynamometers to be very tolerant of static shocks by the users, but the electronics are vulnerable when
the electronics are exposed. ESD occurs as a result of a difference of potential between two objects
when the two objects touch. Damage occurs as a result of the energy released when the discharge
(touch) occurs. The difference of potential can accumulate by as simple an action as a user moving
across carpet or a seat. If that person’s energy is discharged directly to the electronics, the electronics
can be damaged.
Precautions
To protect against ESD damage, you must eliminate the difference of potential before the electronics
are handled. Touch the chassis of the dynamometer before touching any of the electronics. By touching
the chassis, you discharge any static shocks to the chassis instead of to the electronics.
If you are holding a circuit board or dynamometer component in your hand when you approach the
machine, touch the chassis of the dynamometer with your hand before installing the circuit board or
component.
When handling a circuit board or component to someone, touch that person with your hand first,
then hand them the component.
Always carry circuit boards in anti-static bags when the boards are exposed (removed from the
dynamometer).
Battery Fire and Explosion Hazards
There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer’s instructions.
Automotive Batteries
In operation, batteries generate and release flammable hydrogen gas. They must always be assumed
to contain this gas which, if ignited by burning cigarette, naked flame or spark, may cause battery
explosion with dispersion of casing fragments and corrosive liquid electrolyte. Carefully follow
manufacturer's instructions for installation and service. Keep away all sources of gas ignition and do
not allow metallic articles to simultaneously contact the negative and positive terminals of a battery.
Do not allow the positive and negative terminals to short-circuit. The dynamometer chassis is tied to
the negative side of the battery. Do not short between the positive battery terminal or the starter
connections to the chassis. In addition, make sure metal tools such as screw drivers, wrenches, and
torque wrenches do not come in contact with the negative and positive terminals of the battery. Short
circuiting the terminals of the battery can cause burn injuries, damage to the dynamometer, or trigger
explosions.
Charging
Batteries being charged will generate and release flammable hydrogen gas. Charging space should be
ventilated. Keep battery vent caps in position. Prohibit smoking and avoid creation of flames and sparks
nearby.
Wear protective clothing, eye and face protection, when charging or handling batteries.

Other Potential Hazards
The AC power outlet shall be installed near the equipment and it shall be easily accessible to allow for
disconnect before service.
The dynamometer should be located in a well ventilated area. There is a carbon monoxide hazard with
all internal combustion engines. Engine exhaust contains poisonous carbon monoxide gas. Breathing
it could cause death.
Always wear proper ear and eye protection when operating the dynamometer.
Never operate the dynamometer with the covers removed.
Never stand behind the dynamometer when in operation.

YOUR DYNO ROOM
This section is not meant to imply that a dyno room is essential to repeatable results
on a Dynojet dynamometer. However, a dyno room with an engine cooling intake fan,
exhaust extraction, and noise reduction capabilities can add a new dimension to your
shop.
A proper dyno room design will help to ensure repeatable, accurate runs. A good
dyno room should do the following:
• minimize noise
• provide a controlled environment for testing
• provide a view window (safety glass) for customers
• be designed with safety in mind
Intake Air Fan—After building your dyno room, you will need to supply an intake air
fan. The intake air fan supplies air to cool the bike’s engine while supplying fresh
oxygen for you and your bike to breathe. It is a common misconception that you
cannot tune a bike without a large fan simulating exact road conditions; however, a
good cooling fan is the only requirement for consistent diagnostics and tuning. The
installed fan should be 5200 CFM.

Introduction

Equalizer Box—If the air flow rate coming into the dyno room is greater than the air
flow rate leaving the dyno room, the room will become pressurized. A pressurized
dyno room will make measured power misleading. To compensate, you need an
equalizer box. The equalizer box is a baffled (to reduce noise) vent to the outside of
your dyno room. The size of the equalizer box is dependent on the size of your dyno
room and the size of your fans.
Exhaust Extraction—An exhaust fan is needed to remove exhaust gasses, especially
carbon monoxide, from the dyno room. Carbon monoxide is potentially lethal to
people if not removed from the room and will affect engine power when mixed with
fresh air. Plans for exhaust extraction (P/N 73429201) are available from Dynojet.
Engine exhaust contains poisonous carbon monoxide gas. Breathing it could
cause death. Operate machine in well ventilated area.
Fire Suppression—Always have adequate fire suppression or fire extinguishers in
your dyno room.
Industrial Noise Control, Inc.—Industrial Noise Control, Inc. offers a zinc-coated
steel room custom built to your specifications. This room meets all dyno room
requirements. The dyno room must be clean and dry with a comfortable room air
temperature above 32 degrees Fahrenheit (0 degrees Celsius), and have some system
of exhaust extraction. For more information on a dyno room, refer to your
Pre-Installation Guide For Model 200i, 250i, 200ip, and 250ip Motorcycle
Dynamometers (P/N 98129103).

DYNAMOMETER SPECIFICATIONS AND REQUIREMENTS
The following specifications and requirements will help you set up your dyno area
and verify you have the requirements to operate your dyno safely.
BATTERY REQUIREMENTS
Your 200i/250i dyno is designed to carry a group 24 deep-cycle discharge series
battery for operating the starter, power carriage, and optional wheel clamp. The
typical dimensions for this series of batteries are 27 cm long by 17 cm wide by 23 cm
tall (10.625-inches by 6.75-inches by 9.125-inches). The mounting is flexible so a
battery that has dimensions close to this will work satisfactorily. The built-in battery
cables are configured for top-post batteries. This battery is not included with your
dyno. You will need to provide this battery. For more information on installing the
battery, refer to “Installing the Battery” on page 2-10.
