What Ron says is right and to expand on that thought - Many Revo engined V Rods had initial oil consumption problems, mainly due to hard chrome rings on hard cylinder liners and improper oil for the break-in period - plus many riders that never ran the engines beyond 4-5 grand, even after the break-in period so the result is improperly seated rings, high initial oil consumption, resulting heavy breathing of oil mist into the airbox and contamination of the intake tract and valves, for a long, long time. To me H-D had the break-in riding rules about right in the manual but from new these engines should have been run on break-in mineral oil, Motorcycle Spec, ( not H-D Syn 3 or whatever crap oil they used ) until oil consumption stabilizes, ( hopefully by 400-500 miles ) using ever increasing Rpm limits until you get to 8999 ( no rev limiter hits ), then put in whatever full synthetic wet clutch M/C oil you worship, Amsoil for me, or Mobil 1, Motul etc. and never look back. Instead H-D delivered the bikes with an oil not optimized for proper break-in of basically a high tech, high Rpm race engine that wasn't operated that way by more conservative riders that may not have been used to revving up a V Twin to almost 9000 Rpm. IMHO H-D just didn't want to tell new V Rod owners to return in about 500 miles for a $ 135 oil change from break-in oil to a proper full synthetic - they just don't like to deliver bikes with that short of a honeymoon period so they just took their chances, some finally broke in, some didn't.
It is what it is. And once the rings are fully seated, fit an oil seperator for the long run, I learned that here, it's very important -
