I just bought my gvr4 and the transmission was super notchy. So I adjusted my clutch and the transmission feels 10x better, I assume clutch drag. Anyway question is now about 2 inches from the floor there is an obvious knock in the clutch somewhere. I was wondering what this could be because I have no clue. It doesn't effect performance at all but I want to make sure I'm not hurting anything. Thanks in advance.
