runs to rich

2005 nomad all stock. Took 5-hr trip,outside temp sarted at 28deg, up to 55-high. Bike went rich like flipping a switch, gas mileage went from 35 to 28 mpg. Starts good, runs good, no idiot light came on. On start up you can smell fumes till warm-up. Did not have any prob- last winter on cold rides . Would like to make a dignostic check. Can you tell me where the dignostic plug is and what color, how many wire and color, and which one to jump out to get a reading. Thanks for any help.

Per Kawasaki Nomad Service Manual


Inlet Air Temperature Sensor Output Voltage
Connections to ECU Connector
Meter (+) → P lead (terminal 31)
Meter (–) → BR/BK lead (terminal 11)
•Measure the output voltage of the sensor with the engine
stopped and the connector joined. •Turn the ignition switch ON.
Output Voltage at ECU
Standard: 2.4 V at inlet air temperature 25°C (77°F)
•Turn the ignition switch OFF.
If the output voltage is normal but there is still trouble,
check the sensor resistance.
If the output voltage is about 4.8 V, the ECU is normal.
Remove the right air cleaner base and check the wiring
between the ECU and the sensor.
If the output voltage is not about 4.8 V and out of the specified,
remove the right air cleaner base, check the wiring
between the ECU and the inlet air temperature sensor.
If the wiring is good, check the sensor resistance. •Remove the needle adapters, and apply silicone sealant
to the seals of the connector for waterproofing.
Sealant - Kawasaki Bond (Silicone Sealant): 56019-120


Resistance Inspection •Remove the inlet air temperature sensor. Suspend the sensor in a container of machine oil so
that the heat-sensitive portion and threaded portion are
submerged. •Suspend a thermometer with the heat-sensitive portion
located in almost the same depth with the sensor.
NOTE
○The sensor and thermometer must not touch the container
side or bottom.
•Place the container over a source of heat and gradually
raise the temperature of the oil while stirring the oil gently
for even temperature. •Using a digital meter, measure the internal resistance
of the sensor across the terminals at the temperatures
shown in the table.
Inlet Air Temperature Sensor Resistance
Standard: 5.4 ∼ 6.6 kΩ at 0°C (32°F)
2.26 ∼ 2.86 kΩ at 20°C (68°F)
0.29 ∼ 0.39 kΩ at 80°C (176°F)
If the measurement is out of the range, replace the sensor.

My bike did the exact same thing a couple months ago , smells very rich, poorer mileage etc. I will be checking those sensors when it warms up in a couple of months.

I overfilled my tank once and got gas in my charcoal cannister...It smelled like gas and got crummy mileage for a couple hundred miles, then seemed to improve..

Under the left side cover. It may only be on California models.
