r u talking about the shift lever or the clutch lever itself on the clip on?
no cables to the shift lever (foot)
if your clutch is getting hott it'll get harder to pull and can get stuck in places. when its cooled and sitting in your garage, or what ever, wiggle it and see if it has a bit of "freeplay" before it actually starts to pull and disengage the clutch. You don't want it real tight sitting there from the minute you first pull on it.
