Red face Replacing Forks

Hello All!

So I just got new forks in the mail, and am looking forward to replacing my current bent ones. I've been seeing a lot of advice telling people to "only tighten to spec" because if you tighten the triple tree onto the new forks too tightly, you can pinch them and ruin them. Can someone tell me what the spec tightness is for a 2006 Ninja 250r? I don't have an owner's manual so this info would be great. Also, how do you know when they're tightened to "spec"? Is it just a general gray area or is is very very specific? Any info would be awesome, thanks!

Special torque measuring tool?

How do you measure the torque though? Is there a special tool that I need for this?

There's a torque wrench that measures in inches or foot-pounds.

I believe the upper tree is supposed to be tightened to 20nm (which is equivalent to 14.75ft-lbs.) and the lower tree is supposed to be tightened to 29nm (21.39ft-lbs.) but double-check this link for torque values:
