I am trying to find the proper torque numbers for the bolts that secure the header pipe to the heads. I believe it's something like 10 in/lbs and the you do it to 120 in/lbs. I know there is a sequence to follow as well. I have been searching and searching but I can't find the post that had it all written out. If you guys can provide any help that would be great.


2015 iron 883

 

Since nobody knows I just tightened them down the old school way by hand, and went back and forth between the nuts. It works

 

Sometimes the old ways are the best! If you want service info for your bike there is no substitute for the genuine factory service manual. Has stacks of interesting stuff for those sleepless nights.......

 

I've found that using the recommended torque on where you have squishy gaskets makes no sense.
They will back right out again.
Probably after a series of re adjusting tension after they back out, they will eventually sit and stay? Maybe?
But I just trusted my intuition and took it real slow and got 'em to where one shot was perfect.
No tourque wrench, though I have a set that I use religiously on nuts and bolts that back onto a dead flat backing.
As for sequencing... That don't really matter if you use short turns of a wrench and swap from one on to the other so that each nut moves in at equal rates till they bottom.
Alternating left to right from to and then to the bottom and repeat will be plenty. No need to get super **** LOL
You can feel the gaskets reach their max resistance if you do it this way. And yes.
Tighten 'em till snug, but don't gorilla them down or they will strip.

 

Tighten alternately until seated and snug. Confirm no leaks with brake cleaner while idling. Then recheck them after a few hundred miles as they will have loosened up a bit with everything seating with heat and vibration. Tighten them from there and be done with it!
