Not everything on the bike needs to be torqued down, that drain plug is one of them. Just "snug" it down good, if you're concerned about leakage....use a new crush washer. I've lost one or two over the years and used a new banjo bolt crush washer used on brake lines.
Like the exhaust studs, if you try using a torque wrench on those you'll end up snapping one off. Put the torque wrench away except for the vital stuff such as internal engine parts and such things as axles, etc. You'll spend a lot less time cussing, more time riding.
Well said, John. I always felt it was important to understand what the fasteners purpose is, what the consequence if it were to be over or under tightenen and some basic rules.
The larger the bolt the higher the torque value, small lighter (generally)
If its a "pin" like the bolt that holds the rear brake caliper plate from rotating, or the lower shock bolt on the right (final drive) side...those buggars dont need to be any tighter than a spark plug.
Getting a feel for how tight by size and purpose goes a long way especially for road side work where you dont have every tool in the arsenol
