Logically, when screwing in the cs, one would hold onto the "stopper" portion of the clutchstop to do so. However, when screwing in my cs, the "stopper" portion was loose. I could use the stopper portion to screw the CS in to a point. Then, it would just freely rotate, geting me nowhere. Moreover, that postion is too high for me to engage gears. So, the only thing i could do is get a 17mm open ended wrench and akwardly try to screw the cs in. However, i don't have a 17mm wrench so i took that crap off. Moreover, the total price of that thing is $26.50. For $26.50, it's a bit pricey. And that's not counting the 17mm wrench i need to go buy. Damn....
