Head Torques?????
Hi to all and hope ypu all survived the Christmas hols and got a few miles in.
Plenty of snow in Ireland, first white Christmas for many years, so no go here and anyways, bike is stripped.
Putting it back together now. Have barrells on and fitting heads but just a quickie about torques.
Fitting a James gasket set and they say to torque in sequence and using different settings until a final setting of 38-42 ft-lbs is reached.
The Clymer manual says to torque in sequence until you reach a setting of 12-14 ft-lbs is reached, then mark bolts and heads and tighten 1/4 turn further.
Which method should be used??????
I have not changed headsbolts or studs.
Thanks
Tony.

Probably go with the gasket maker since this is the changed variable. Either would probably work out. The important thing is probably getting them all the same. I sure they are a lot of people who just tighten them by fill. My Softail say 120-144 in/lb, 15-17Lb at a pattern and then 90 degree (1/4 turn) in a slightly different pattern. If you go with finial torque of 38-42 bet its around 90 degree from 15.

Last winter when I picked up the bored cylinders and reconditioned heads I picked up the james gasket kit from the harley mechanic and he said to be sure to follow the directions on the box.

The Harley method if done with a good beam type torque wrench and lubed head bolts will come out to about 42 lbs. Early on most good mechanics figured this out and use the straight torque method regularly. Hope this helps
