I was adjusting my clutch and throttle cables on my 400ex and used a regular wrench with a shop towel rapped around it to break loose and tighten the lock nuts on theses cables. This is a hassle and I feel like there has to be a tool made for this task that will mesh with the splines on the lock nuts. Does this tool exist? If so where could I find one?

 

Yes those tools exist...follow your left or right arm down until you hit the end. [img]i/expressions/face-icon-small-smile.gif[/img]

All kidding aside, they're meant to be finger tight though often times they need a pliers to break them loose. I've used a pliers before and it doesn't really seem to mess up the surfaces.
