My gas tank appears to be leaking engine oil

There is oil on the underside of it, on the wires, running down the front and sides of the bike. Its enough oil its smoky when I stop.

At first I thought the tach wire, but I tighened it and I dont see how that would fling oil up to the gas tank and top of engine. The breather cover is soaked.

Anything I should try before buying new gaskets?
 
Clean and dry everything. Spray the whole top of engine and all gasket cracks with powdered foot spray. Start bike. Easy to see where the leaks are.
 
valve cover gasket leaks are common, oil can end up all over while riding. Rich has the right idea....clean and investigate
 
Is the oem gasket yellow?

Ill try to clean it up when the engine gets cold.

Right next to the tach cable the gasket stops being as visible I suspect that might be the place.

Wonder if the bike shop can quickly get me parts.

Do you have a hose attached to the breather cover nipple?
 
That'll definitely smoke if it comes loose. It gives your clothes that nice-just rode a motorcycle- fragrance too.

Oil VAPOR, yes, but only if there is not a hose connecting the breather cover to the airbox.

You have pods on your bike, so you are not accustomed to that concept.

Smoke is coming from the exhaust parts that the oil hits, then it evaporates or burns and makes smoke.
 
I guess I need to clean it, figure out where the leak is from, and then ride it for a long trip to measure how much oil I lose per kilometer.

A bit worried about my Oslo trip now.

Could I just use liquid gasket?

But what I wouldn't give for that just-rode-a-motorcycle fragrance. :( (I think I'll go rub some wrenches on my ribs.)
 
50 mph wind, from riding a bike, will blow oil where you wouldn't think, from where you wouldn't think. Tightening the tach cable?? there are 2 or 3 seals & "O" rings in that little rascal. It takes a whale of a (very baaad) oil leak to make the eng. show low of oil within a few hundred miles.
 
You obviously don't know the oil consumption habits of my 1000E. To make matters worse, then are no areas that show leakage.
 
Oil consumption without leaks, kind'f odd for a GS. They're not really known for burning oil even after many many miles.

With the oil filter cover leak I had earlier I could have it leak almost nothing, or have it leak 0.8 litres in 500 kilometers depending on how I rode it. It feels like it leaks more now, but I think the oil is maybe just spread on a bigger area.

But I guess I will fill it up to F and do a scientific test. Sort of want to go to Senja, some people say its prettier than Lofoten where I spend a lot of my time.
 
After market Valve cover gaskets can be slightly off and that's all it takes to spew oil

I had one let go when I was coming back from Mt St Helens and it oiled my boot a lot. I had installed it about 6 months prior

Fortunately, I had an OEM spare on the wall. More fortunately, I swapped over to my GPz and finished the rally

I am now thinking I can have my wife cut me a new gasket for it. I need to replace the bolts anyways, and then I can do a second attempt at removing the intake boot screws with proper JIS screwdrivers. The wait for a new one I am afraid will be longer than I can go without it. Then I could check the valve clearance too.

I am going to order a bunch of parts soon though, to get what I need for the winter fixing.
 
You'll likely needs hand impact driver to remove the intake bolts
