According to the Haynes manual, the spec is 80 Nm which converts to roughly 59 ft-lbs. So 57 ft-lbs is probably correct.I am using the PDF copy of the factory service manual that has been around since 2009. It calls for 57 Ft. Lbs torque on the rear sprocket nuts. That sounds too high, and when I try to tighten them to that value it feels too tight. Anyone know of an updated spec.?
