118 F (48 C) is forecast for the middle of next week .
All of the BMW's require premium grade of fuel this time of year .
But, surprisingly, the Guzzi is the least finicky for premium fuel of the bikes in hot weather !!!
Running the last of regular fuel out of it this weekend, no detonation with it, unless you try to accelerate in too high of a gear for the speed .
It's 'happier' in the higher rpm range .
Most of the newer construction homes here ( last 20 years), don't come with 'swamp coolers', or evaporative cooling .
Not real conducive to adding it to the home, without significant modifications .
