GS1000G Torque Spefications

[feelergaugephil]

My GS is near enough complete, after 6 long months of restoring it.
The manual states that the head torque settings are:- 27.0 ft lbs and the 2 out bolts are:- 6.5ft lbs.
The engine has been completely rebuilt and both gasket facing sides of head/barrels been bead blasted, I had the head and barrels checked at a machine shop and were completely true, (straight)
My question is, it is near enough run in now, and was wondering whats the highest amount (safely) can I go upto in ft.lbs as I know the GS range is prone to head gasket leaks.
I dont want to go crazy, like some people do. just enough as not bust out the head.
It has all new upper nuts and washers, including the 4 copper washers on the outers.
And, should the engine be warm or cold when torqueing it up.
Compression is 170-175 across the board.
OH! its a GS1000G 1981, cheers guys. Phil.

You shouldn't need to go any higher than the recomended 27 ft lbs. if everything went together nice and clean. I retorqued mine after 200 miles and was amazed at how they all needed to be tightened up again. I checked again at 500 miles and they were all fine. Torque figures are for a cold engine as far as I know, but if I'm wrong someone will soon tell you.

Engine cold, also when torquing, as I learned in aviation, torque the bolts in the pattern and torque called for in the manual, wait 5 min and repeat as many times as nessary, till no more movement on any of the bolts(or nuts) is noticed, this has served me well on my bikes, you DO NOT NEED to increase the torque more than called for in the manual, I did this on my head gasket change 10 years ago on my GS1000G, and nary a leak
