Do you enough freeplay at the lever & actuator? Important to check both ends because something could be physically stopping the arm at the bottom from returning to where it should.Originally Posted by B.Crump

If so, start by dismantling the clutch & measuing the fibres & steels and check for any damage on them and the clutch basket & cover. Check the spring free length.
What sort of oil is in the gearbox? Car engine oil, although available in the correct viscosity, is unsuitable because the friction modifiers are not compatible with wet clutches and can cause them to slip.

ATF is fine.
How about the play on the clutch actuator lever on the box? Does it move much before coming into contact with the clutch rod? It should have a return coil spring on it to turn it back the other way to what happens when you pull the clutch lever in.
Disassembling the clutch is a relatively easy task but if you've never done it before I suggest you have someone who has done it before show you.

The TF is an old suzuki design & a bitch to take apart until you sit & think about it. There is no pushrod, just a pull mechanism on the near side.
Likely just worn out, however two cheap bodges to get more pressure on the plates is
1. to fit another steel plate.
But (2) on the TF the clutch springs are threaded on & you should be able to wind them in some more to get more tension.
This makes them even more of a bitch to service but you need to get some decent tools. The springs are hooked at one end & have a pin through them which retains the plate. You need to use a spring hook or some needle-nose vice grips to pull the springs a bit while using some other pliers on the pins. Becomes easy when you decide to use the right tools, else you will just lever them & send the pins shooting across the garage & under the bench or whatever never to be found.

I think you need to use some sort of spell checker. Most browsers have an option to turn one on.
Also answers in above post. Google spring puller, can make one from an old spoke with a filed nipple & a piece of broom handle
