I have a evo 1200 engine on my 93 sportster and I lost two nuts off exhaust pipe that hold flange onto engine good thing I had it bolted on tight to mount cuz it was a close one for a engine rebuild lol so I didn't torque them last time but I think I want to this time around lol please help me with torque specs so I can get job done and not have to worry about it I have drag pipes and I got some nice copper crush gaskets this time also because the mesh ones I used last time were ones that came with the exhaust and they leaked from day one

 

I know, not the same bike. But mine is 100 in/lbs.

 

So that's like 10 ft lbs ithink

 

The spec is 96-120 inch-lbs.
If you want to put an end to the nuts coming loose, I recommend ordering a set of these ARP nuts. They have elliptical threads which are self locking.

 

100 in-lbs/12 in per foot = 8.333 ft-lbs

 

So I set my torque wrench as low as it would go which was like 5 or 6 ft lbs I think and I snapped front cylinder top bolt off into engine wtf yea so my bikes going to my friends shop tomorrow

 

This is why the torque spec is given in inch pounds.
Torque wrenches are inherently not accurate at either end of their range.
For 100 inch/lbs, you ideally want to use something like a 10 - 250 inch pounds torque wrench, so that the torque you're trying to achieve is somewhere closer to the center of the torque range of the wrench, rather at an extreme end.
