All the harley owners I've ever known are always working on their bike. Something is always broken or needs fixing/maint.
My dad used to go riding with about 20 guys... but it was almost always cut in half... cause half couldn't go... cause they drove Harleys.
Just talking from experiance... I shouldn't catergorize allllllllllll harley owners... but just all the ones that I've ever seen.
