R lbf.ft).
R (6) Temporarily install the fixed fairing (1) with the bolts (2), (8) and
R (12).
R (7) Measure the dimension A, this must be between 7.5 mm (0.30 in.) and
R 9.5 mm (0.37 in.).
R (8) If the dimension A is not correct, remove the bolts (2), (8) and (12)
R and the fixed fairing (1), and continue as follows:
