Only thing I notice is a little bit of oil in the base gasket area but not enough to worry about i guess.

What is an evo engine by harley. A WLA 45 well those date back to 1945. And then using the term blockhead are very contradictoryNobody that I ever knew who owned a Harley called the Evolution anything but EVOsBlockhead as a Term. Blockhead 1984-99 All Blockheads have the same displacement of 80 cubic inches.

See what set these Harley-Davidsons apart. The first Evo was a shovel based engine with the Evo non-vented heads. They are also called Evolution or Evo.

This will get you into looking at copies of Harley parts books for your year. I like the engine but the new ones are probably far better. The Evolution engine on Harleys 1100 models has a larger bore --- at 34 inches --- and the same 38-inch stoke.

There is a hose going to the frame. THE EVOLUTION MOTOR. Twinkies seem to have some issues heat is one of them hence the piss-heads coming out now but I dont know enough guys with twinkies to give any real stats.

I suspect youre asking of. Probably the first in Harleys history. If not then pull the oil pressure sending unit and crank over with out starting untill the oil is out.

The evo motor is a reliable motor. Engine to save the company. Under the frame is the drain plug.
