After reading this thread, I figured that I would put in my 2cents...
Roy, I think Hammond Harley is great for diagnosing / fixing your Aftermarket Clutch issues.
Cam, 'can feel your frustration, (I would have probably "lost it" long ago!) Your issue (and maybe a few others) might have spawned the most recent recall? 'Really hope it solves your problems!
Jerry, I agree with you, some of the HD techs, I wouldn't let work on my bicycle but, (there's always a "but" with me these days. LOL at self). Like yourself, I have direct (Tech) experience with OEMs and 'have been an Independent as well (Outboard Motors). With OE, we relied more on the Manufacturer for Diagnostic Procedures and Parts Replacement, if the OEM didn't have the proper Parts or Procedures, life could be difficult for us (we hated being relegated to "educated parts changers"~ sometimes that's all we could do!) and The Customer, then some kind of Recall / TSB would usually be initiated (To my knowledge there is no OEM that doesn't operate in this manner ~ The Customer is a guinea pig). As my knowledge progressed, and I was attending the OEM (OMC & Mercury) "Top Gun" Schools, we were placed in the Test Cells with the Engineers to assist with writing Procedures on the soon to be launched Engine Programs, it made sense to me, that the OEMs gave us credit for knowing what worked in the real world. Then as an Independent with a lot of time in the saddle (like Steve) we could pretty much Diagnose over the phone and be correct... We used to bitch (brag) about having to "fix the $hit that the OEMs should have designed properly in the first place" or (Automotive / Inboard/Outboards) "I'd like to get the engineers by the nuts, and tell them, You come work on this POS!"
I'm really surprised that The MoCo hasn't had more issues with the Rushmores, we'll see as the time / miles progress...
