Thanks, Roger, The Rotax bulletin and video actually inspired my question as I have previously purged the system using these instructions. The video advises extra precaution when purging systems using a thermostat but gives no details. Do you agree with James and Bill that the thermostat bypassses enough oil when cold to purge the cooler side assuming a full cooler with inlet and outlet at the top?

Do you think the higher range thermostats would tend to raise the temp of the oil when it exceeds the opening temp of the thermostat?
If I see 215F. on a hot day with high power settings without a thermostat would I see any highter readings under identical circumstanmces with the 205F. thermostat?
My main concern is lower oil pressure readings at anything under 180F. with high power settings apparantly due to oil pump starvation. Maybe the 190F. is a good place to start. Incidently, I am using the semi-synthetic 20/40 Shell oil. Thanks again.
