My Second $500 K75 Project

Good call on the fan motor - I'll wait until it's running and I service the cooling system.  But I'm going to order a new fuel vent line and the wires because I'd rather mess around with fuel once and be done with it.  I'm not in a hurry.

This weekend I mostly just cleaned things up some.  While giving it a wash, I was reminded that the rear cowl lid had a broken tab and a PO held it in place with gorilla tape.  I got this idea somewhere, and it worked perfectly for a non-abs bike.

It's just a bit of kit to mount a fender on a bicycle that I bent 90*.

So I got it running today.  Lots of smoke initially (I did shoot some fogging oil in the cylinders last weekend), but it seems to run as well as my RT.  Who'da knowd fresh gas vs old gas/varnish/water was the ticket?

The one thing I'm not clear on is why so much moisture exited the muffler when it was running.  I noticed some dripping where the header and muffler connect before I tried to start it, and assumed it was somehow accumulated from sitting outside, but it seems kind of like oily coolant.  I need to get some distilled water to fill the system and let it get up to temperature, I guess.

I decided to add distilled water to see what would happen, and there's coolant getting into the oil.  The level in the sight glass was milky looking and went up, and the watery exhaust didn't quit.  I'm going to drain the oil and coolant and take a look at the pump.  Maybe the prior rebuild was done poorly or the shaft was reused in poor shape.

The engine had good compression when I checked, so wasn't ready to blame the head gasket, but the wet and smoking exhaust is making me think maybe.
