Oil leak, cam chain galley at head gasket

So after about 3X the money and 10X the time I had figured to get my 1100E project rolling.. it is rolling. Runs like a top, but I have a pretty significant oil leak at the head gasket, right in the center in front of the cam chain galley. Its pretty messy after only 20 miles... and if I can get my confidence up in this bike we're doing an SS1000 in June... so I can't let it go.

Is there any hope in retorquing, or is it out w/ the motor and off w/ her head?

I already had the motor out once to drill out 4 broken exhaust bolts.. guess I'll be fast at it this time...

Then of course at that point I might as well re-ring and hone the ol' girl. 20,400 miles.
 
Is this a new head gasket?

If its new then they recommend a retorque after allow it to get to
full temp and then letting it cool overnight.

If its an old gasket, it probably won't help.
 
This bike sure makes me appreciate simplicity. From the time I rolled into my garage to the time the motor was on my bench - about an hour - and I was in no rush.

It takes me nearly 2.5 hrs to do a complete oil change on my KTM.
 
Also try some thread sealer on the little bolts located outside the 1&4 spark plugs and the center front.
Try a retourque but chances are you need a new head gasket and at the same time a base gasket.
 
I went ahead and pulled the motor. I should have the head off tonight. I'll do all top end gaskets (base included) and I think new rings and a hone job while I'm at it, assuming everything is well in spec.
 
O-Rings

O-Rings

The two head bolts in the center front have o-rings on the top of them. When the o-rings are bad, it looks just like a leaking head gasket.

Let me guess, you see oil dripping from the small 6mm inverted bolt right at the front of the engine? I have had the same exact oil weep ever since I owned my 1100. I can't seem to get rid of it. I have brand new OEM gaskets, o-rings, and that dam friggin' bolt is always moist with oil.

I also can't figure out why my stator cover gasket (also new) leaks oil on to my left boot whenever I do over 5000 rpms for an extended period of time (over 30 min.). I guess GS's simply are oil leaky bikes just like old Harleys.

Road Clam, I'll bet the oil on your foot is coming from the mystery hole under your starter. Most likely, oil is getting past the rubber grommet your stator wires go through, or the o-ring on the starter is bad. The oil works its way into the compartment where the starter is and leaks out of the drain under the starter. Just pull your starter cover and see if any oil is present.

Mine don't leak, they are never below 5,000 except if stopped.
Get in there and fix something.

Very interesting.....

I will have to purchase a 6pak, and research this further.... thanks!
