Saw on the dealership floor the other day two CVO models and noticed a factory sticker on the primary cover that says all three holes factory filled with synthetics. Don't know if its the same synthetic in all three, but just the same. I didn't think Synthetic was good for breaking in an engine.

Putting the same engine oil in a tranny sounds to me weird.
Please under stand this is my first Harley 09 SG.

If this is your first Harley, what did you ride before? Most Jap bikes have one hole for everything--the same oil is lubricating the engine, clutch, and tranny. Did you think that was wierd? At least the Harley separates the primary and tranny oil from the engine oil.

LOL, Beary, your comparison to cars reminds me of a middle aged student we had in MSF instructor prep class, who could not understand the ratcheting mechanism of a motorcycle's shifter. Because the position of his car's gear shift lever changed with each gear, he refused to believe that was not also true with cycles, and was constantly looking down at his shift lever to see what gear he was in. Halfway through the class all 12 of us instructor students were convinced he was a ringer put in the class so our instructors could see how each one of us would handle a problem student.
He didn't pass the course.

Same here...
+1 on that for me. After break-in, went to Amsoil 20/50 for all 3, much quieter shifting, & a cooler running engine.

What do you or HD consider proper break in period before switching over to full Syn thetics? Will Amsoil 20/50 meet warranty for a new bike?

Visc. for SAE 50 is 16.3-21.9. (20W50)
Visc. for SAE 90 is 13.5-24.0. (75W90)
This is why it is OK to use the same oil in all 3 holes.
