b. When piston #1 is at TDC on the compres-
sion stroke, align the "I" mark "a" on the gen-
erator rotor with the stationary pointer "b" on

when the cylinder #1 camshaft lobes are
turned away from each other.
• In order to be sure that the piston is at TDC, the
alignment marks "c" on the intake camshaft
sprocket and the alignment marks "d" on the
exhaust camshaft sprocket must align with the
cylinder head mating surface as shown in the
illustration.
