1982 gpz 750 clutch cable routing, need help!

I need to know the correct way to route clutch cable. I have it coming up left frame rail between 1 and 2 cylinders, up to oil cooler, then under triple clamp, then up to clutch lever, is that correct. It gets tight sometimes doesn't completely disengages clutch. Any help would be appreciated.

Pic. It should run between 1/2, the in front of the lower triple tree, behind the headlight and to the perch.
