I have gone through my manual and can find nothing about the head bolt
torque. Don't know if it will help, but nightrider.com has a page on torque
specs. They indicate that, if you don't know, torque based on fastener size.
I think that the studs are 5/16", so should be 19 ft lbs (if you buy this).
Don't know how the process on the lightweights compares to the Sportster,
but this outlines that process - remember that the Sportster uses 7/16"
Head Bolt Installation
For each cylinder head, start with head bolt numbered one. In increasing
number sequence (1-2-3-4), tighten the head bolt in three stages.
1. Tighten each bolt to 7-9 foot pounds of torque.
2, Tighten each bolt to 12-14 foot pounds of torque.
3. Mark each head bolt and head with aligning marks. Tighten each bolt 1/4
turn (90 degrees).
Hard to believe that the manual doesn't cover this.
