Secure so that the Setscrews are engaged
in the D-shade recess
Tighten the Setscrews 4 x 6mm evenly on all
sides of the Tail Drive Joint to ensure no runout.
Optional : Install typical 4mm
diameter governor magnet in
provided clutch bores with a drop
of thin CA.
Be sure the Setscrew 4x4mm is installed
onto the flat spot on the start shaft to
prevent it from slipping.
Leave a small amount of play between the
starter hex adapter and start shaft bearing
block while installing the Setscrew 4x4
onto the start shaft, otherwise the Clutch
Bell Assembly may not rotate freely.
NOTE: Your kit also includes JR red and
green threadlock. Unlike conventional
U.S.-made threadlock, JR red is the
U.S. equivalent of blue. JR green is the
equivalent of U.S. red.
