Better Gas Mileage for my 2011 RS-S
1. Check the front and rear wheel alignment and correct if not aligned. Check your front end aligment.
2. Clean fuel system.
I use Marine Stable,
at 1/2 oz. per 5 gallons of gas.
3. Use 89+ octane gas.
4. Tire pressure that are correct for your Spyder.
5. Synthetic motorcycle oil. I use Amsoil 10-40 synthetic motorcycle oil. There
are a lot of brand names on the market to choose
from.
6. Air filter. I use a K&N air filter in my 2011 RS-S. I removed the rubber air tubes that are
in the front of the air box.I cut off the front of the rubber air tubes down by 1/3rd.
7. When pulling out, without traffic, get to speed by shifting at 5,000 rpm's.
2. When on highways run the rpms at 5,000 to 6,000 to maintane speed.
3. When on other road run the rpms above 4,500 to keep in the engines powerband.
4. When starting a cold engine, let it warm up for 1 minute.
5. When ridding do not let your gas tank go below a 1/4 of a tank of gas.
When you get less that 2 gallons in the tank the gas will stat to evaporate at a high
rate and the gas/alcohol starts to separate. If the Spyder stopped and engine is hot the gas will
start to boil if your below a 1/4 of a tank.
8. Spark plugs and wires. Use Iridium spark plugs and custom ignition wires, I got mine from BajRon and
they are high quality parts.
9. Air Scoops. These will keep the engine and the air box cooler and they are easy to make. See this thread:
