| - | Oil that has a wide viscosity range, i.e. 10W50. The "W" stands for Winter therefore 10W50 oil has a viscosity range from SAE10 when cold to SAE50 when hot. ((Haynes Sportster manual 1970-2010 pg REF*50)) | + | Motor or gear oil that has a wide viscosity range (meeting the requirements of more than one SAE viscosity grade) and thus it can be used in a wider temperature range., i.e. 10W50. The "W" stands for Winter therefore 10W50 oil has a viscosity range from SAE10 when cold to SAE50 when hot.

| ===== Multimeter ===== | ===== Multimeter ===== | ||
| - | A testing instrument for most electrical things on a motorcycle. There are variations in makes and models but most come with the ability to check for voltage, continuity and resistance (Ohms). Some do not have a buzzer to sound off when continuity is broken but this is a very important feature to have. | + | A testing instrument for most electrical things on a motorcycle.
