My 84 Honda Nighthawk had the same problem. Turns out the clutch fluid return port was plugged. It's a small pinhole in the master cylinder that bleeds pressure back to the reservoir when the clutch lever is released. Otherwise pressure builds up in the system and keeps the clutch disengaged. It's easy to check, just pump the clutch lever a dozen times and open the air bleed plug (on the slave cylinder on my bike) there should be no pressure. If fluid squirts out under pressure, this is most likely the problem.
Hello Timbr. Thanks for this comment. I just fixed the clutch in my 1986 Cavalcade by cleaning out the small pinhole in the master cylinder as you described. Note that when the port is clean, fluid will squirt up like a fountain when the lever is pulled, if it is plugged, there will be no fluid flow from the pressure bleed hole back to the reservoir.

Check your oil level all so because this will give u clutch slipage as if as well
Did you replace the clutch springs with the original ones? or with Barnett ones? the latter are much stronger and will not slip, unlike the original ones. Barnett ones are available from www.cademaster.com under cavalcade parts.
SOURCE: the clutch started slipping. is
Ah yes! The missing clue! You put more stuff in the gearbox. But what exactly did you put in it? Motorcycle engines do not do well using synthetic oil, or oils with "special" additives or "friction reducers". Drain whatever is in the gearbox and refill with 10w40 motor oil. Shell, Mobil, Quaker State. Any major brand will do. It may require a one hour ride and a second oil change to rid the gearbox of the synthetic. Clutch plates that swell are usually toast. Plates that just slip usually recover after awhile. Install a new oil filter. Look it up in the manual. See below.
A “very helpful” rating on this answer? Thanks!
SOURCE: CLUTCH BUILDS PRESSURE AS IT GETS HOTTER.
try replacing the fluid on this and bleed system good,clutch adjust may be needed
SOURCE: It seems that my clutch fluid is getting hot and
sounds like the clutch needs to be adjusted, loosen the clutch adjusting jam nut and turn the adj screw clockwise untill the bike bearly starts to creep forward, then back off the screw 1/4 turn, tighten jam nut and you should be good to go
