Problem
I dont know if this can be anything to do with it but my b&m ripper is kind of noisy/whiney/notchy. And i have a spohn rod ended tunnel mount t/a.
I've hit it before once or twice with my stock shifter, but when I installed my B&M Ripper, the problem went away for some reason.
Did you adjust the set screw stops on the B&M? This feature is supposed to prevent the shift forks from being over-extended and bent.
