Anyone else having this issue? I had a 3 88 inchers that did this then my last one on a Ultra I had upgraded to a 95 and it quit. Now It seems my 103 is puking oil thru the breather.
I thought I'd ask you'll before I ask the shop to get a idea if this is normal. you'd think since they got the problem resolved in the 95 cu in they'd carried it over to the 103's,

 

my fat bot used to do that, and its was time to change the filter, and then i put heavy breather on and that solved it all

 

nothing like that so far, but then I've only gotten 500 miles on her!

 

I haven't had that problem since overfilling my 97 Ultra

 

I rebuilt mine did 103 buddy said I should go gravity. Not really sure what he meant but I guess it blows out the unspent fuel thru hose on bottom instead of putting it back into the cylinder. Also keeps piston cleaner not having the crap building up should of listened. Should of took time to understand better. It's Not always happening but I do notice oils on cam cover then I clean filter and wipe oil off.

 

Several things can cause excessive oil to blow out the crankcase breather into the air cleaner (to be sucked into the intake to burn up - it's an EPA thing).
Over filling oil.
Too much water in the oil evaporating (that's the point of the breathers, to exhaust water vapor, a natural by-product of combustion) - the water vapor brings a little oil with it).
And, I've seen on a few motors, Rings worn with seemingly low miles (when rings are worn, the pressure in the combustion chamber forces air past the rings into the crankcase, and it has to escape somewhere so it exhausts thru the crankcase breather taking oil with it - do a leak down test to determine - that's why upgrading your TC88 to TC95 fixed it - new rings)
Harley provides dealer with acceptable amount of oil loss between oil changes so you dealer will probably say "normal".

 

My 96 does it intermittently. Just kinda learned to ignore it. A drop here a couple of drops there.

 

Just to reiterate what Weavr99FLHT said, at my recent 1K service, I was talking to the tech about things I'd be doing myself, and on oil changes, he warned me not to fill it to the "full" mark on the stick. Leave the oil level a little below that, for the reason you bring up.

 

I have a 2011 limited with about 7500 miles and I have not noticed any so far, pretty much left it stock.

 

My 2011 Ultra Limited did it. They found out not to fill it full. My oil level had to stay about half below the mark then no problems
