You may want to take a look at this, I used it to "break in" my engine a couple of years ago, and it seems to have worked a treat.
Have talked to many Harley independants over the last couple of years about this very subject and most agree with it, Too do a good job with "Piston Ring to Cylnderwall" sealing, dont use "synthetic" oils and ride it like you stole it!
I changed my oil after 50 miles, then again after another 200, and didnt start using "rock oil TRM" untill had 1,000 on the clock.
I have "no oil " usage at all, with exception of the very small amount from the breather system (I use a catch can to keep the cylinders and pistons crowns clean).
