There have already been many reports of slipping issues on the Harley version of a "slipper" clutch, since day one. So Scott is right on the money, it's pretty much "normal" when Harley introduces anything "new", even though it's only new to Harley and not the rest of the industry. They managed to screw up their first attempt at ABS, even though other companies have had it for decades without issues. Their first attempts at EFI sucked, their versions of a cam chain tensioner sucked big time, their attempt to run an overdrive primary and a direct drive 6th gear has caused nothing but problems even though Baker did it before them without all the problems, they still haven't figured out how to manufacture a reliable crankshaft, they couldn't come out with a super simple liquid cooling system without multiple problems and recalls, etc.. And the best part is they come out with new-to-them stuff and don't test it before unleashing it on the general public. Wonderfull bunch of incompetent clowns that can't get much right but still make money hand over fist. I find that last part to be the saddest of all.
