Glossary of Terms:

Bore: Diameter of cylinder.
BTDC: Before Top Dead Center.
Bump Steer: When skis toe in and toe out through suspension travel.
CDI: Capacitor Discharge Ignition. Ignition system which stores voltage generated by the stator plate exciter coil in a

electronic switch (thyristor) in the CDI box and allows the voltage in the capacitor to discharge into the primary windings of
the ignition coil.
Center Cylinder: On three cylinder engines, the cylinder between Mag and PTO ends.

Clutch Offset: Drive and driven clutches are offset so that drive belt will stay nearly straight as it moves along the clutch face
as the engine torques back.
Clutch Weights: Three levers in the drive clutch which relative to their weight, profile and engine RPM cause the drive
