When to Re-Torque

This has got me curious. I looked on page C-3 of the 2010 Dyna Service Manual for the conversions of inch lbs to ft lbs, and it came out to around 9.9 ft lbs of torque (10 lbs). I got the torque wrench out. I had a bolt on each that needed a good bit of tightening to bring them to spec.
I have doubts about the gaskets on my bike being that the first pipe was bad, then the stocks put back on, and then they put the T-headers on.
Like the other more experienced HD riders here have said. They will loosen up on ya, but I bet the finally get settled. I bet I have do to the same as you soon, and change out my gaskets. I get some popping now and then.

Anything under fifteen-twenty foot pounds and I don't trust my foot lb wrench. I have three -- A 1/2" drive foot lb, a 3/8" foot pound and 1/4" drive inch pound. Yeah, they're cheap suckers. Cheap, cheap. But so what? You can buy a $400 Snap On and use it twice a year and it'll go to hell on you from just sitting. Or you can do like me and buy the dirt cheap ones form Harbor Freight and realize that they're not totally accurate but still better than taking a wild guess.
Then throw it away if you don't trust it anymore.

Your math is not correct in figuring the inch lbs to foot lbs conversion.
The equation is (inch lbs value (0.08333) = ft. lbs).
So 100 inch lbs would be 8.33 ft. lbs, and not 12 ft. lbs.
I mean you could be as much as 4 ft lbs off if not done correctly. That could multiply quickly if a large amount of torque was called for, and you could end up breaking something. It just all depends on how precise you want to be.
Here is an online reference http://www.convertunits.com/from/inch+lbs/to/foot+lbs

Yes.
I guess it all cancels out. I have an excuse for being a dumb *** right now. I have a 9 month pregnant woman who will not let me sleep..

I did the math my self as far as the divide by 12 conversion, my book called for 9-18inch pounds on the bottom nut then 100-120inch pounds on the top nut, then back down to the bottom nut to 100-120inch pounds. So I set the torque wrench to 10Ftlbs and went to town. I guesstimated the 9-18inch pounds and then torqued the rest to specs. No issues. Super Easy.
