Gene, 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). http://www.nightrider.com/biketech/hdtorquevalues.htm 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" bolts... Head Bolt Installation Factory Method 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. CJ ----- ORIGINAL MESSAGE FOLLOWS ----- What is the proper torque value for the head bolts Also what is the best gasket sealant to use? |
