their way-
From left side of the motorcycle use a three foot length of 2x4 wood as a pry bar. Insert the flat side of the wood between the left frame down tube and front cylinder. Use just enough pressure to move the motor slightly to the right and install the long screw (5) and washer (4) in the lower right side of the bracket.
my way-
use a chrome SHCS.(I always try to replace everything with chrome bolts).
