Picked this up from Ebay last year when I blew my loose starter clutch apart with a high rev.
.
Because the 3 bolts holding it in place where loose, (No locktite, nor were they peened at all), the starter clutch was giving me that "Box of Rocks" sound at startup.
I left it for a while (my fault), because I learned to double tap the starter when that sound happened, which in most cases, I could get the bike to start.
Well, the imbalance caused the thin plate that covers the rollers on the back of the clutch to explode. This caused a piece of that plate, to knock my pulser pick-up, out of position of the flywheel magnet. (No spark after that).. This left me stranded - 40 miles from home.
Once I found the problem, I ordered this clutch and decided, not only to put RED locktite,, but to clean off the bolts, and bolt holes with acetone and denatured alcohol, mounted the clutch, then let it sit for the recommended 24 hours for locktite to fully harden.. THEN, I peened the bolt ends into the flywheel, as suggested in Sean Morley's Videos on Youtube (below). I didn't want to take a chance of shifting the bolts at all, during the peening process,, so I let the locktite harden. And I don't want to go back in there any time soon. :eusa_dance:
So far, no more "Box of Rocks" sounds at startup.
