I must be missing the thread that states this but I just snooped around for half an hour and can't find it. Harley told me for my bike it's 3 quarts in the engine, and 1 each in the primary and tranny. I put the HD premium full synthetic 20w50 in the engine and HD formula+ in the gearbox and primary. but it seems to make a little more noise than usual. Did they tell me the wrong quantities? engine dipstick shows full, gearbox dipstick shows full, but something tells me the primary is still low. I don't know. My sporty took almost a quart and a half to get the oil to the bottom of the primary chain. since the Dyna's primary is much bigger, how can it possibly be just one quart??? am I missing something?
