My chunks aren't as big as yours, I'm assuming that they're from the jackshaft.
I won't have time to rip it apart till next Thursday to see for sure, but when I slid by to arrange for the shop time I was shown a set of the easys... I'm told that this grinding comes as an option on some of the finer models, and if I don't do something other than repair the broken parts now I'm going to be making the same repair down the road.
The grind never happened when the bike was cold, only hot... I assumed the compression release would have been sufficient to address the problem but apparently not.
Based on what I've read from S&S it seems like they would work in theory, but like others, I'm worried about that tiny hunk of metal fluttering around on the cam, centrifugal force or not!
Thanks for the input.
