(Refer to manual for this vehicle for normal safe engine temperature)

sponds with which cylinder
4. Loosen spark plugs
5. Clean spark plug wells with appropriate tools. We suggest an air blow gun and or wire
brush.
6. Set throttle position wide open and remove the air filter from the vehicle
Remember to reset throttle position after completing test failure to do so could
result in serious damage to engine and/or self
7. Disconnect the ignition system following manufacturers recommendations
8. From the kit select the proper adaptor and screw into the hose and then into the spark
plug well. Hand tighten the adaptor into the well. You do not need to use a wrench to
apply extra force, hand tight is correct for the test.
9. Connect the gauge to the hose and make sure that all fittings are correct and tight.
Vehicle is now ready for test. As a final precaution please review the above steps to
make sure that all instructions have been followed.
