What does a breather tube do motorcycle?
Purpose of a Crankcase Breather Tube As the pistons move, they compress the air trapped within the crankcase, creating pressure that escapes through a vent.

What kind of oil filter does a 1975 Shovelhead have?
Bought a 1975 Shovelhead a while back from a very shady character and among other things, when you start the engine, it starts puking tons of oil all over the floor. There is a braided metal line about 6-8″ long with a small filter on the end of it. Looks like a crank case breather line, on the right side of the engine.

When you crank or start the engine oil is then forced out the breather. As long as it stops after a minute or two you are probably OK. The longer the bike sits between starts the more oil there will be.

Why does my 81 Flt blow out oil?
My 81 FLT blows out some oil when sitting more than 3or so days, out the crank case breather tube. It should not be plugged and have no idea why someone would do that. The crank case has to have vent for internal pressure relief.
