 +===== Micrometer =====
 +A precision instrument used to measure outside diameters of parts
 +===== Microwelding =====
 +Adherence of sporadic particles of aluminum from the piston to the bottom side of the piston ring. ((http://​papers.sae.org/​960745/​))
 +===== Monograde Oil =====
 +Oil with a single viscosity, i.e. SAE80W. AKA Straight Oil
 +===== Multigrade Oil =====
 +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. ((Haynes Sportster manual 1970-2010 pg REF*50))((http://​www.oilspecifications.org/​articles/​lubrication-glossary.php))
 +===== 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.
