On what bike? You have a real problem if it is a big twin.
is it possible for oil to go from the primary to the oil tank Don't do new scooters that have a sealed Primary so no....but, shovelheads had an oil line from the oil pump to the back of the primary case to oil the primary chain and yes, it went back into the oil tank. Sorta recirculated ya know.. I sealed my '80 fxwg just so the primary oil didn't go back to the tank. And..... newer bikes hold a lot more oil in their primary. I put only about 4 oz in mine sealed!!
