I agree that if my slave was failing and I kept putting excessive force the fork would have bent (warping of side flanges). Fact that it ripped makes me suspect defect around the rivet hole.
Hey Yun,
All is well, thanks and hoping the same with you and family. I have been buried with work/school and inactive lately. Yes, timing was good for failure as a positive point like when mine (clutch slave) failed and I was at the traffic signal by my home; had to grind a few gears in the process. That rivet area does seem like it could be a weak point and defect as you stated. These forks seems to be a pretty stout item and I wonder where originally made and what quality of metal used? I guess the stuff from Jim Jandik is the best we can get being OEM stuff. Take care and thanks again for sharing.
