Jetting for fun & profit
Tom Chop was on around 40 mpg after break-in. After installing V&H`s and a Speed`s Performance breather, I re-jetted and maintained 40 mpg +or-. For those who are interested I had mains-0.074, intermediate-0.032, and air bleed-0.040.
Now down to the skinny--I live in the deep south. The tempratures here are extremely hot. Our Government, in it`s infinite wisdom, at decided to add at 10 to 15 percent methanol (alcohol). This mixture ends up making the fuels you buy cause our carburated air cooled engines run leaner. That is because there are not as many BTU`s (British Thermal Units) in relation to gasoline by volume. As an old rodder I know it takes roughly twice as much alcohol to equal the BTU`s that are in gasoline. This is supposed to save gas? It causes My mileage to drop 5 to 7 per cent, savings?
Now down to the worst part. While on a ride with a bro noticed I my scooter "pinging". I downshifted and that stopped that shit temporarily, but I was pissed and concerned.
I got the bike home and called a friend who works at a local oil refinery. Jocko informed me that the fuel in our area had been re-formulated this summer to include ethanol . Shit! But that isn`t all--we can look for more and more to be introduced from time to time in the future. Thanks Uncle Sam.
To Hell with the EPA-let our grand kids figure figure it out and we`ll keep screaming around on our beloved Big Dogs!
