Can you post some pics.You shouldn't be having that much trouble!
How's it line up height wise?that adjuster that holds the cable should be backed out so that the end is just inside the stud.
I wouldn't let it float you could leave it loose,then adjust your clutch and lock your lever.
Then lock it down.If you leave it loose you are going to be pulling on your threads every time you use your clutch and those aluminum threads will eventually fail.
Is your cable kinked,how's your clutch cable routed? it has to flow as freely as possible.
Is the cable lubricated inside?
I have a method that works very well PM me and I'll explain it to you!Kip.
