Hey all, new guy here looking for some help. I'm new here and new to motorcycles and vehicle maintenance in general, so apologies in advance as I learn. I bought a 1978 CB750 Super Sport and looking to learn and grow as I work on this baby to hopefully bring her to her former glory. I've started with some basics; spark plugs, oil/filter change, rebuilt brakes and master cylinders, and cleaned and mostly rebuilt carbs. It sat for about 4 years but I've got it running and it sounds pretty solid to me. I did a cold compression test prior to any attempts at starting and got 60's across all 4. I haven't done another compression since having it running - hoping to have much better figures after I do the next test.
Now on to the question...after changing the oil and having it running I noticed a drip coming from the front of the engine. The source is coming from the tach line where it enters the top of the engine. I realize I can simply replace the gasket/o ring seal and that should take care of the leak, so not really any worries there. My concern/question is about the color/consistency of the fluid. It's a rust color and looks kind of watery. Is that normal or of concern? Is that what new engine oil should look like coming from the tach drive port?
