Harley Davidson 1200 sportster `91?

Question

My sportster has just emptied the contents of the oil tank through the engine breather , engine was idling , oil light flashed on / off and then it happened . Any ideas where to start looking for the cause

Answer 1

Or your oil return got blocked and it dumped out

if just rubber oil lines the inner lining will come loose and block a line sometimes

Answer 2

I agree with Indian John.

Answer 3

Milwaukee

Answer 4

no well clued up on harleys but i had a bike that sucked oil through the breather pipe.it was down to a blocked air filter.hope this helps

Answer 5

had the same prob with my 95,the base gaskets let go

Answer 6

Yeah, the crankcase vent system is blocked up somehow. Excessive crank pressure. Maybe the rings or pistons are worn and the crankcase pressure is built WAY up. That 's odd to lose that much oil that way. Blocked oil gallery?
