NOTE: To check the fluid level with the dipstick, the motorcycle should be sitting level to the ground
and the dipstick resting on top of the threads. The fluid should be up to the FULL mark on the dipstick.
NOTE: To adjust the shifter drum, remove the top cover and put the transmission into 3rd gear. The
shifter pawl arm should be centered on 2 pins on the left side of shifter drum. If you need to adjust the
shifter pawl arm, loosen the lock nut on the centering screw. Turn the centering screw clockwise or
counterclockwise to center the shifter pawl arm on the 2 pins. Torque the centering screw lock nut 33-
38 ft. lbs. and re-install the top cover with a new gasket and torque the top cover screws. (see chart
above)
NOTE: To check the air gap on speedometer sensor to gear, remove the speedometer sensor and
measure the depth of the hole (trap door to top of one gear tooth) using a dial caliper or depth mi-
crometer and record this measurement. Now measure the speedometer sensor from the surface that
slides into trap door (where the sensor sets on trap door to end of speedometer sensor) and record
this measurement. Subtract door to gear measurement from speedometer sensor measurement and
this is you air gap.
NOTE: It is strongly recommended to re-torque all fasteners on a monthly basis.
