Anyone know off the top of their head? I'm getting some popping so I think they need to be tightened up to stop the leak. I'm gonna use the ol cigar smoke method, but I want to make sure I know the specs before I go torquing the bolts down. Thanks boys!

I assume no liability. 120in lbs. Get some 5/16x24 serrated flange nuts and they will never back off again.

 

Can I get them through Harley? I need to make a run there this week anyway

 

No. Go to local fastenal or fastener store. Not usually at ace but you never know.

 

This may nitpicking but I use 108 in. lbs since that is the center of the suggested range

 

you're not the only one that is that way... I will always go dead center of a "suggested range"

 

98-120 IN lbs or 8-10 FT lbs

 

I've seen a lot of posts about the flange nuts being torqued to 90-120 in/lbs when doing some reading before changing my exhaust. I also found this pdf

when researching it. This says to torque them to 60-80 in/lbs. Any idea where the difference comes from? And assuming these values are incorrect, and I need to re torque them to 100 in/lb, is it as easy as loosening the pope support bracket and then tightening them to the new torque or will I have to loosen the entire system first?

 

Got it guys, torqued it down and no more leaks.
