Torque really necessary?

I figure NGK know more about spark plugs than me, so don't use a torque wrench on them.

In those cases it is indeed a case of Torque is cheap

I only ever lube my chain in 1st gear.

Your spraying it, you don't need your fingers anywhere near the sprockets.

Tighten until it shears then back 1/4 turn

Somthing it tighten to the correct setting, some i do up to what i feel is tight.

?

I use the torque setting for the spark plugs as set by kawasaki, as they make the head.

NGK reckon finger tight plus half a turn to crush the washer*. Plenty IMO since you're just making a gas seal.

*For their flat washer type plugs

i think the the abuse of spark plugs comes from over tightening.

Common misconception this, The torque wrench is adjustable, often to figures of lower than "b@asrd stiff" In fact, if you use the low figure just to the side of the "sump nut" in you manual it'll be fine.

This pre-supposes that the torque wrench works. Some people have damaged things by leaning seriously hard on a torque wrench that's set wrong, sheared the bolt and then blamed the tool. The common sense factor has to come in somewhere.

Careless torque costs lives

A torque wrench might save some grief, but be aware that they are available in different sizes for different jobs. An 18" 100ftlb wrench is worse than useless when bolts need say 15ftlb.
