Anybody know how many pounds to torque the head pipes? Or, just do it the old fashion way?

 

My exhaust flanges are torqued to 100-120 in lbs, but there is a sequence involved too - you can get an electronic version of your HD Service Manual online for ~ $6.

 

Torque the top nut 9-18 in-lb. Torque the bottom nut 120 in-lb. Torque the top nut 120 in-lb.
