As Verslagen said, the lever on the clutch cover (on the engine) should be between the two marks on the engine case. Look behind where the cable attaches to the lever, there should be two marks on the engine case.
When the clutch lever on the handlebars is released, that lever on the clutch cover needs to be situated between those two marks on the engine case, and there should also be slack in the system. There should be slack in the lever on the handlebars, and you should be able to pull on the lever on the clutch cover and observe it move up a bit. There must be free play in order for the clutch to fully engage.
If that lever on the clutch cover doesn't line up with the marks on the engine case, you either have the cable too tight such that its pulling up on the engine lever and partially disengaging the clutch, or the clutch pushrod is the wrong length.
If you go to any Suzuki parts website (patzilla, babbitts, etc.) and look at the fiche for the clutch assembly, you will note that piece 22 comes in three different lengths (44.5mm, 45.5mm, & 46.5mm). If the lever on the clutch cover is too low in relation to the marks on the engine case, you need a shorter pushrod. If the lever is too high in relation to the marks on the engine case you need a longer pushrod.
All that being said, what sort of clutch plates and springs did you install? Did you install genuine Suzuki parts, or did you install some sort of aftermarket parts. I can tell you that I tested EBC clutch springs and they are not up to the task.
