AM I RIGHT IN THINKING THAT A WEEPY HEAD (ON THE GS) CAN BE NIPPED UP OR AM I IN NEED OF GASKETS?
Give it a go, and see what happens

cylinder head for sure
What bike?
The 1100 had a problem with head gaskets. After 3 attempts they finally got it sorted with a multilayer one that can be retroffited to the earlier bikes.

Course of antibiotics sorted it for me!

if you are going to 'nip it up' the head bolts make sure you start from the beging ie initial torque than add you angles as the manual says
the gasket ( if its an 1150) is an MLS ( multi layered steel) gasket and does not need to be re-torque as old fibre types do ( as long as they have been correctlt fitted)
from another thread but applicable
Course of antibiotics sorted it for me!
Torque plus angle is used on 'strech' bolts, after intial torque is applied the angle has been calculated and tested to give the correct amount of strech to the bolt.
At the pre determined angle the bolt goes into its elastic state and its clamp load increases.
As you can imagine the graph of the strech rises rapidly, then flattens off and drops very rapidly corresponding to the amount of angle applied.
Its at the top of this cure where the most clamp load is generated, the torque plus angle is calculated to put you in this area.
Overstep this slightly and the load will drop rapidly.
Sometimes the manufactures will recommened that new 'strech' bolts are fitted to some areas to ensure maximum clamp load
I am sure we have all experienced tighten a bolt up, it get harder and the.....goes loose just before it snaps
Thats a prime example of taking the material out of its 'elastic' state

1100 had crap gasket?
It took mine about 50,000ks before trouble? Yes the old Single Layer Gasket was no good. Make sure you fit a multi layer. Watch your timing of the Cam Sprokets (Mine never lined up propper as the w/shop manual) Don't drop the cam chain in the sump. How old is your motor? Consider Valve Rubbers while you have it pulled down? It's not hard. Easy to work on. BIGJim Tasmania.
