I don't run a thermostat, never have.
Never had a prob getting my oil up to temp...I'm in East TN.
if you have probs getting the oil to temp...ride harder! You'll get there!
I know what you mean, getting the temps up here are no problem. It does look like I am going to have to use the adapter, just get one without the thermostat. And then I will also get the lock that Jagg has to keep it from loosening up when removing the filter
