"Check the voltage at the battery terminals, and make sure to record the voltage down to the tenths: 12.6v vs. 12v. Check the following values:
-After the bike has been sitting for days, key off: No lower than 12.2v, and even that's pretty low. You really want more like 12.6-12.8.
-As you're cranking the starter: No less than 10v.
-At idle: Voltage should be no lower than the "sitting voltage" you measured above.
-In normal rpm range (4000-9000): 13.8v is ideal, but anything 13.5-13.8 is OK.
-Immediately (within half an hour) after a ride of at least 10-15 miles at over 4000 rpm, engine and key off: 12.8v or more.
A day or two after that ride, key off: 12.6v or higher"
