Is it that you are finding it hard to find neutral while stationary? If so, have a look at your clutch. Set it up to lift clean and even. Check your lever. I have found that the common 7/8" fulcrum type do not lift far enough. I have replaced mine with a 1 1/16" type and the plates separate nicely now. I have no trouble finding neutral and this is with a six spring swinging arm clutch.
I have gone to the trouble of modifying the pressure plate with a radial needle bearing and mushroom lifter. Next time I open the chaincase I will replace the adjusting nuts with single nyloc nuts.

Yes, it will be the clutch getting hot and dragging. Check that the plates are not warped, they are lifting off evenly and the clutch centre and basket are not notched by the plate tenons. These notches and any burrs on the tenons can be rectified with a file.
