Magnum cooling

The fact that you can get the engine running "too cool" still works. Even if not for "emissions" reasons there are reasons to run the engine a little warmer... 180-200 running temp is NOT overheating. With too low temps you're not burning off condensation in the crankcase, and fuel wise fuel puddling isn't good even if not an "emissions tuned"ride.
I agree with that. There's also the time involved. An engine that runs 180 for short trips for example, is worse off than an engine that runs 165-170 on longer trips. That's why I constantly say "it's all in the tune", because that's true. Were we live, it's about 25 minutes to the closest town we drive to, Gray. That's about the shortest trip we take. Otherwise, it's about 30 miles to Macon and the same to Milledgeville.
