Hello fellow enthusiasts:
I am just outside Brussels heading to Dusseldorf. It's my yearly summer trip. My head gasket is leaking ever so slightly on the right cylinder. It's not a big problem, yet. Does anyone know if there is a parts guy/enthusiast in this area? If I can get the part, I can probably swap it in a parking lot, if i have to.
Any helpful suggestions appreciated.

google motorcycle shop

google motorcycle shop brussels. A number of places come up. Start calling and ask some questions...maybe you can get a lead. On the other side of Dusseldorf is Motorrad Stemler. Check out the website:

http://www.motorrad-stemler.de/

Call...maybe you can make it there and buy something from them.

Leak is coming from the top

Leak is coming from the top side between pushrod tubes. Very tiny bubbles in an inconsistent pattern - seems like more activity when working hard at lower rpms.
I did bear down a bit on the head bolts earlier, and intend to do so again in the morning (check valves too) but I don't have a torque wrench, and don't want to make things worse. For what it's worth, the bolts turn smoothly, but they already feel tight. Hard to guess how tight, though.

You didn't say what bike?

You didn't say what bike? R69S or not? R69s has 6 bolts, the top and bottom one are steel into aluminum. For the non R69S, I believe there are only 4 bolts that go through the rockers. Don't these thread into the steel cylinder? The head bolt torque is around 25 ft-lbs. If you give it a good grunt with a wrench from the tool kit...not a huge breaker bar...and it still leaks, then you have a head gasket problem.

Head Gasket

Between the pushrod tubes is a pretty common place for the head gasket to start leaking, it likely won't get worse. When you do replace the head gasket, check the head on a surface plate or piece of glass. What is likely is the head is a bit warped, I see this very often. Lay a sheet of sand paper on the glass and rub the head on the sand paper until the head is flat or until the area between the pushrod tubes starts to clean up. Fit a new head gasket and away you go.
