It seems there are questions about the Oil Temperature Sensor (OTS) from time to time. Yesterday I moved the fuel tank back and installed a 10K Ohm potentiometer in place of the OTS, connected the GS-911 and adjusted the pot until the temperature list below showed on the GS-911. Then I measured the resistance of the pot and noted the number of bars on the RID. I estimate that the resistances are about +/-5% accurate.
The OTS is used by the rider to monitor Oil Temperature on the RID (Rider Information Display); and by the Motronic (together with the Air Temperature Sensor (ATS)) for cold starting and warm-up. Roughly speaking, there is about a 15% enrichment at 40F which tapers to 4% by 140F (or after a preset time since starting), at which time the Motronic runs in Closed Loop. The amount of enrichment and changeover to Closed Loop is also partly dependent on the ATS.
