3dogs makes his share of good points, especially his Rule #1.
Since this is an oil change thread and there might be some other newbies out there like me, I'll mention my first oil change. Having owned a 650 Bonneville back in the 60's, I developed early phobias about stuff vibrating loose from motorcycles -- those vertical twins shook everything loose. Starting with a clean slate on this 05 FJR i decided to go by the book. Long story short, the torque specs for both the oil filter and drain plug seem way too high, and after reading another thread about overtightened/stripped drain plugs i'm glad common sense stopped me short of the 31 ft/lbs torque spec for the drain plug. Same with the filter -- spun it on until the filter gasket touched -- after tightening the filter another 3/4 to full revolution the torque wrench still hadn't clicked to the owners manual torque spec, but even this old Bonny owner knew when to stop tightening! One forum member suggested going 10%-20% below the torque specs, so maybe he is onto something.
