Made a BIG mistake while leading a friend on her Spyder of taking the Cades Cove Loop. It was clear as we got on it, but about 200 yards into the 10 mile single-lane loop we came up behind gawkers lined up and refusing to take pull-offs (like so many signs indicated). Two and a half hours later, we finally made it through. T 'wing was doing Ok, cycling the fans until about half way through. Then I found that I needed to run the RPMs up to about 2k to move the water cooled in the radiator to the block and bring the temps down. 3/4 through and I saw the needle climb to almost H. Near the very end, it went to past H (but still no steam or puking). It took almost three miles of 35-40 mph mostly downhill to get the needle back to its normal spot at the lower end of the operating range. I plan to buy a new jug of Rotella tomorrow and change the oil.
