You can run a compression test. I don't beleive that the twin Kohlers have a compression release so it should work. Just compare the readings on both cylinders. They should be real close. It also may be leaking oil from the head gasket. If the compression is fime and you don't mind the oil leak don't worry about it. Just keep an eye on the oil level.

It sounds like an oil pressure galley leak at the head gasket.I wouldnt run it like that.you are risking seizing the motor,if that small leak gets big,which it will as the hot ,oil eats away at the gasket more,you might run out of oil,or starve the rocker/valve train on that side.Just fix it or get it fixed,the leak will only get worse.Compression on my CV25 is 189 left/187 right.These engine have extremely high cranking pressure for an air cooled motor,you just want to see that the compression is within 5-8 lbs per cylinder,whatever that#is.I check my compression a lot since Im concerned about blowing another head gasket.

you might want to chk the valve covers as I have seen them leak looking like a head gasket leaking,you will want to get it hot before taking the compression test as it will expand the most when hot

The new covers are also plastic. You might have cracked it somehow.

Here is a tip for helping find oil leaks on an engine.

Clean the motor completely and then apply "Baby Powder Soft & Dry" spray on deoderant to the area in question. Run the motor and within a few minutes the powder will show you where any leaks are.

I did not think this up myself... It is a Harley owners trick....
