Fluid Requirements - Buell S1 Lightning Workshop Manual

GENERAL
United States System
Unless otherwise specified, all fluid volume measurements
in this Service Manual are expressed in United States
(U.S.) units-of-measure. See below:
1 pint (U.S.) = 16 fluid ounces (U.S.)
1 quart (U.S.) = 2 pints (U.S.) = 32 fl. oz. (U.S.)
1 gallon (U.S.) = 4 quarts (U.S.) = 128 fl. oz. (U.S.)
Metric System
Fluid volume measurements in this Service Manual include
the metric system equivalents. In the metric system, 1 liter
(L) = 1,000 milliliters (mL). Should you need to convert from
U.S. units-of-measure to metric units-of-measure (or vice
versa), refer to the following:
fluid ounces (U.S.) x 29.574 = milliliters
pints (U.S.) x 0.473 = liters
quarts (U.S.) x 0.946 = liters
gallons (U.S.) x 3.785 = liters
milliliters x 0.0338 = fluid ounces (U.S.)
liters x 2.114 = pints (U.S.)
liters x 1.057 = quarts (U.S.)
liters x 0.264 = gallons (U.S.)
STEERING HEAD BEARING
GREASE
Use WHEEL BEARING GREASE (Part No. 99855-89).
