103's with oil comming thru breather?
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,

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".
