I think you'll have to supply a bit more information or even better a pic or two before you'll get much advice on this question.
Is it the alternator side or the points side of the c/case? or is it between the barrels & the c/case?
I'm sure help will come.

Left or right side?

There is a vent on the back of the cam cover. Should have a tube that drops behind the motor near the swingarm pivot. There is also a vent tube from the inside, top of the oil tank. The most common source of spewing oil on K1's is the oil tank vent drain, which should be connected to the nipple on the lower rear crankcase. That's the best I can guess, without more info.

EDIT; the oil tank drain comment should be followed with an "ask me how I know"
