I just put a Brawler solo on my RKC, and the damn thing keeps sliding back, that nut on the rear won't hold the seat in place. The chrome bracket from the seat is slotted and I can't get the effer tight enough to stay in place. Anybody else have this happen? Does HD make a slotted shim/washer to hold this in place? If I tighten the nut any tighter I'm going to snap off the stud.
Have you checked if it is the right part nr for your ride?
Yes, it is the right number. I think it's slotted to fit a couple applications. I think I'll machine a shim for this. That should keep my fat *** from pushing the seat backwards!!
