This past weekend I was riding the smoky Mountains and noticed that the oil pressure gauge was reading 0. Immediately stopped and assured that there was oil. The gauge is on the pin, absolute 0. It does not move at all with engine rev. SOOO probably the gauge or wiring. How do I find out which one is the problem? I really don't know where the sensor is located either. Any help??

If you're not getting any other signs of oil starvation (i.e. motor failure), it's probably the sensor/sending unit. Is your bike under warranty? If so, call dealer for advice. If not - get a service manual and look into swapping the unit.

 

This is what the manual says:



If the low oil pressure light functions correctly, but the pressure gauge does not, then proceed as follows:

• Remove electrical connector from oil pressure sending unit. Turn the ignition
  switch to IGNITION. The gauge must read zero.
• Ground (BN/GN) wire terminal to crankcase. The gauge must read full scale 60
  PSI (414 kPa).
• Replace the sending unit if the above gauge readings are obtained. If the gauge
  readings are not obtained, then replace the pressure gauge.

 

Well there ya go then. Sounds like what I shall do. Thanks for the reply's. Now exactly where is that little sending unit?

Go to Ronnies Microfiche website, where you can see exploded diagrams that will answer your question. It is probably on the top of the cam chest (my bike is earlier than yours).
