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. 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.

WARN IN GS
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
dyn amo me ter s to be v er y to ler ant of sta tic sho ck s 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 handing 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.

WAR NIN GS
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.
Any dyno room design must incorporate sufficient exhaust extraction.
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.
Never operate the dynamometer when there is excessive vibration or noise. Resolve these problems
before proceeding.
Never fuel the vehicle on the dynamometer unless appropriate safety measures are taken.
Verify brake operation before beginning any dynamometer testing.
Verify the vehicle is properly secured to the dynamometer.
Never operate the blowers without the guards installed.
Exercise care with any dynamometer testing; portions of the dynamometer and vehicle may become
hot.
As with any equipment using electricity and having moving parts, there are potential hazards. To use
this dynamometer safely, the operator should become familiar with the instructions for operation of
the dynamometer and always exercise care when using it.
Do not repair or replace any part of the dynamometer or attempt any servicing unless specifically
recommended in published user-repair instructions that you understand and have the skills to carry
out.

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.
SPECIFICATIONS AND OPERATING REQUIREMENTS
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).

Connecting the RPM Pickup
CONNECTING THE RPM PICKUP
Your Dynojet dynamometer includes a primary wire inductive pickup and two
secondary wire inductive pickups. These small “clothespin like” inductive pickups are
used to sense RPM. An RPM pickup is required if you want to view torque graphs.
Generally you will use one secondary wire inductive pickup on a spark plug wire.
Vehicles with wasted spark ignition systems may require two secondary inductive
pickups. On a wasted spark ignition, typically one coil will be connected to two spark
plug wires. Attach one secondary pickup to each of these wires. If the pickups are
connected to two plug wires that do not fire at the same time, an erratic RPM readout
may occur. The primary wire inductive pickup senses RPM pulses from the coil.
Although this pickup location generally works better, it is harder to find the correct
location to connect the RPM pickup.
Note: If a pickup is not being used, disconnect it from the dyno electronics to
prevent any stray pick up of signals.
Inductive pickups are very fragile. The ferrite core can easily be damaged and
is not covered under warranty. Dropping, snapping, vibration, and heat can all
damage the ferrite core.
RPM pickup description
Secondaries (Non- wasted spark system) Use one secondary pickup. Unplug the other pickup from the RPM
Secondaries (Wasted spark ignition
system)
Primary pickup Attach the primary wire pickup to the primary side of the coil. Set
The dyno electronics RPM module contains the electronics that sense the RPM pulses.
An auto-gain circuit looks at only the peak voltage of the vehicle’s spark, ignoring the
lower voltages to help reduce electronic noise problems. Wasted spark ignition
systems will produce a lower voltage level on the exhaust stroke than the
compression stroke. By definition of the auto-gain circuit, lower voltage spark levels
will be ignored, missing every other spark the vehicle would produce.

module and set the degrees between plug fires to 720° in WinPEP 7.
Use two secondary pickups. Attach one pickup on each spark plug
wire on the same coil and set the degrees between plug fires to 360°

the degrees between plug fires by taking 720 (four cycle engines) or
360 (two cycle engines) divided by the number of coils. For
example, the number of degrees between plug fires on a four
cylinder four cycle engine with dual coils (where each coil fires two
cylinders) is 720/4 x 2 = 360°.

The inductive pickups contain a fragile Ferrite Core that is sensitive to engine
heat and vibration. Do not drop the inductive pickup or snap the pickup
closed. Use extreme care in handling and placement of the pickups.
BASIC DYNO OPERATION
Connecting the RPM Pickup
1 Clip the secondary inductive pickup around one spark plug wire.
Note: On a wasted spark ignition system, two secondary inductive pickup wires
may be needed.
2 Route the inductive pickup cable clear of devices that produce electronic noise
(spark plug wires, coil wire, coil etc.) to the dyno electronics RPM module.
Note: Inductive pickup placement is important. Position the inductive pickup so
that it is not making contact with any other spark plug wires. Separate the spark
plug wire from the spark plug wire bundle for proper operation.
Note: You must ground the vehicle to the dyno for the electronics to function
properly.

PRE-RUN INSPECTION
Perform a vehicle inspection before making a run. Check the following:
• Check the radiator coolant (if applicable) and oil levels.
•Check the fuel source.
• Rotate the drum and check for rocks caught in the tire tread that could fly out.
• For scooters equipped with a drive chain, check the chain and the chain master
link. Make sure it is lubricated and adjusted to the proper tension.
• Check the tire pressure and tire speed rating. Improperly inflated tires or
exceeding the maximum speed rating can result in premature wear or severe tire
damage. Make sure the tire has no major deficiencies (cracks in sidewalls, tread life,
etc.).
• Visually inspect the vehicle. Make sure it is in safe running order.
• Make sure ear protection and safety glasses are used when the dyno is being
operated.
• Check the tie-down straps to make sure that they are tight and secured.
BASIC DYNO OPERATION
Pre-Run Inspection
• Check the drive tires to be sure that they are aligned correctly on the
dynamometer’s drums.
• Keep all rotating components clear at all times.
• Only the operator should be near the dyno or the vehicle during the test.
• Never allow any person(s) to stand behind the dyno or vehicle when it is being
operated.
• Perform any other safety inspections appropriate to running your vehicle on the
dyno.
Never allow any person(s) to stand behind the dyno or vehicle when it is being
operated. Only the operator should be near the dyno or the vehicle during the
test.

CHAPTER 3
Pre-Run Inspection
BEFORE STARTING THE ENGINE
Connect an exhaust hose or hoses (if dual exhaust) on the vehicle, make sure the
hose fits over the tail pipe, is not plugged or kinked and the hose is vented correctly
out of the dyno room.
Engine exhaust contains poisonous carbon monoxide gas. Breathing it could
cause death. Operate machine in well ventilated area.
ENGINE WARM UP
Warm the vehicle’s engine and drivetrain before beginning testing. Consistent engine
temperatures will assure your runs are repeatable.
AFTER ENGINE WARM UP
Always leave the vehicle in neutral (automatic transmission) or in first gear (manual
transmission), with the engine off, and make sure the park brake and the dyno brake
are on when you get off the vehicle on the dyno.
• Fix any fuel, oil, or coolant leaks that may have shown up after engine warm up and
check the carburetor for leaks.
• Any loud or unusual engine noises or excessive exhaust smoke should be resolved
before continuing.

MAKING A TEST RUN
Dyno runs provide safe, reliable road testing right in the shop. The dyno allows you to
measure, record, and diagnose performance problems quickly. The dyno combined
with WinPEP 7 produces consistent, easily interpretable power graphs. Use the
following instructions to ensure repeatable and accurate measurements.
1 Verify the vehicle is secured properly.
2 Release the dyno brake by pressing the brake pedal.
3 Slowly accelerate the vehicle to 20 m.p.h.
4 Test the tachometer operation.
4a Rev the engine. The gauges on the computer screen should be moving. If
the tachometer is moving but not registering the correct RPM values, the
number of degrees of revolution of the crank shaft (the plug fires number) is
incorrect.
4b Stop the vehicle, return to the MakeRun Configuration dialog box, and enter
the correct value for the plug firing order.
5 Step off the brake pedal to apply 100% braking and slow down the vehicle.
BASIC DYNO OPERATION
Making a Test Run
Using the vehicle’s own brakes to slow or stop the drum at speeds over 30
m.p.h. can severely over heat the brake parts. The vehicle’s brakes should be
used in an emergency stop situation only.
6 Shut the engine off and put the vehicle in gear (manual transmission) or apply the
parking brake (automatic transmission).
7 Set the vehicle’s parking brake and leave the dyno brake on.
8 Perform a final inspection.
• Verify the drive tire’s alignment on the dyno drums.
• Make any adjustments to the tie-down straps as needed.
• Perform any other safety checks that you deem appropriate to your particular
situation.
You are now ready to make a high speed run on the dyno. Refer to your WinPep 7
User Guide for more detailed instructions.

Preventative Maintenance
PREVENTATIVE MAINTENANCE
This section contains basic preventative maintenance and troubleshooting
information.
To maintain proper dynamometer operation, Dynojet recommends you make routine
checks of the dyno.
• Drum—keep the drum clean and keep all objects clear of the drum.
• Carriage Slide—keep the carriage slide clean and lightly lubricated.
ADJUSTING THE BRAKE
Use the following instructions to prevent the brake from dragging.
1 Remove any vehicles from the dyno.
2 Push the brake pedal until it stops.
3 Using your hand, turn the drum.
4 Verify the brake is not dragging.
5 If the brake is dragging, adjust the brake.
Using a 7/16 open end wrench, adjust the brake stop bolt until there is no brake
drag.
Note: Adjusting the bolt too loose or too tight can cause brake drag.

1 Locate the eyebolt brake tension adjuster.
2 With the brake release pedal in the up position, turn the 1/4-20 nut on the eyebolt
clockwise to increase the spring tension until the drum can no longer be turned
by hand.
3 Verify the brake releases when the pedal is fully depressed.
Note: The eyebolt can be adjusted until it touches the lever on the release shaft
mechanism. If the eyebolt makes contact when the brake release pedal is fully
depressed, then the eyebolt has been adjusted too far. Back off the eyebolt nut
until it no longer contacts the lever.
