I speculate the grenade spring does two things:
1) From a stop slightly slips the clutch for smoother engagement.
2) At speed, absorbs the shock/ clunk between gear shifting

Yes I wish a HD engineer would explain for sure.
Yes it seems it is the brass rivets that fail, and if built with better metals/ components
maybe the grenade plate is a good idea.

Interesting topic, who what where why when was this idea implemented.

The spring plate gives you a larger friction zone

I dont care about the reasons behind harley putting that stupid plate in! I dont l I've in that bubble and it exploded on me at about 25,000 miles and I haven't been able to ride her for over a week now! It's a stupid design and sad that they make them just strong enough to make it past the warranty. Seriously thinking about the new Indian Scouts.

Having almost 75 k miles on my 2012 XL 1200 factory clutch and primary chain, riding and clutching as smooth as silk...

Maybe the wrong riding habbits?

Well perhaps it was my riding style, this is my first bike and I did buy it used with about 12,000 miles, it's a 2006 883low, but still.

The 2004-6 rubbermounts (maybe later) seem more likely to have this problem. If you go over to xlforum.net they have a long running poll about this measured by mileage. 80% of the reported clutch spring plate failures are on rubbermounts.

Once you've got your kevlar plates in and are riding again, I'm sure such thoughts will quickly fade! You've had a tough time sorting out your bike, but there is life afterwards.....

Agreed, and many brands have a bit of "why the hell did they do it this way" engineering, from small trail bikes to jumbo jets. Sometimes just a small tweak or mod makes them the bike you want. I was lucky and caught my 1200's rivets before any let go, and just accept that someone at Harley had a difference of opinion on using brass rivets in a high stress area. My sportster is still enjoyable and now I have more peace of mind not having to worry about that issue.

Yes, my experiences working on several friends' Chevy's comes to mind on that one.
