New plastic-region tightening bolts
To tighten the plastic-region tightening bolts, tighten them to the specified torque, and then tighten
them to the specified angle. By tightening the bolts to the specified angle, they are contracted to a
more accurate torque, making periodic maintenance checks and adjustments to, as well as addi-
tional tightening of the bolt unnecessary.
The cylinder head bolts, connecting rod bolts, and crankcase bolts have adopted this method to
help better control torque accuracy.
