i have a 92 heritage softail i have redone the tins ect done nothing motor wise other than change the plugs, i went for a few rides last fall with no problems, when i fill it with gas for the first time since replacing the tins there is oil blowing thru what i think is a crankcase breather, its a line that comes out of the motor and goes into the side of the air cleaner and as soon as i start it now it blows lots of oil thru that tube, what could cause this and how do i fix it, any help would be much appreciated thanks

 

It could be too much oil in your oil tank. Try filling it to halfway up the dipstick and see what happens. It is a very common problem to have "blowby" on a Harley.
