1) Why is SUNOCO the only gasoline for NASCAR ? I have been aware of varying qualities of fuel for most of my motor traveling life. It all started when I ran out of fuel in the foot hills of southern California while riding my mini-bike that I bought with my paper route earnings. This was in the late 50's. A fine gentleman who was in the area with his son also riding offered a fill up at no charge. I accepted the offer. When I fired up my mini-bike which had a centrifical clutch powered by a two cycle Techumsa engine, the power from the low octane introduced, was not sufficient enough to pull the lowliest hill. I drained the fuel out in disgust and pushed it up over the top of the biggest hill and coasted most of the way home. In those days you could buy Chevron 102 octane for less than 35 cents and I believe that's what got me there.
In highschool I street raced a 59 Ford Galaxy 352 CI 4bbl nothing else but Chevron 102 and beat more formidable oppenents only because they had not a clue on the fuel.
Recently my SUNOCO station was going under new ownership and a face lift that stopped my fuel of choice and opted for the only other station that had 93 octane which was BP. It ran OK but I thought I felt a difference in lack of the performance I was used to. When my SUNOCO station got back on track and my first tank full back to the fuel of choice made a real difference.
There are no Chevron stations on the east coast that I know of.
I will admit that no matter what fuel you use consistently, there are always variants that you have no control over.
I have been using SUNOCO 93 for over 15 years now, even in my weedwacker. My SUNOCO stations have stopped offering 94 octane since before I got the STSSE or I would have it in now.
2) When I ride, I ride with full leathers Competition jacket, Vangard chaps, Stealthflame modular helmet, and perforated gloves. The only time I won't is when it's better than 90 degrees. I can guarantee you that I am cooler inside my leathers during the summer months than any body wearing a vest and or t-shirt while moving. Most of the guys that knew this are dead now. The leather protects my body from the sun, and the air moving thru my jacket keeps me cool and even gives a chill when I have stopped and regained speed, evaporation and forced air is a natural airconditioning phenomenon. From some of the looks I get from passing riders they must think just the opposite.
Lastly, you have seen the testicles hanging below the bumper of some vehicles out there, well I am buying a new Rocker and attaching a dil-- onto the fender for my new girl frend
