Jackie, water is a byproduct of combustion. Look at the tailpipe of almost any running engine; it’ll be dripping.

Hello Doug I believe in this case it goes a little deeper than condensation. The Sportster has a really bad miss it's had new heads and pistons installed recently by someone whom I'm wondering if they knew what they were doing. It had a exhaust manifold bolt missing and a big gap between the flange and the head that has to be a tight fit. It's not. So I believe it may have valve damage exhaust side. I currently have the jug/ head removed. A big pile of carbon surrounding that valve.

Stem. Also I'm inspecting the carb exccelarator pump ..
