all of those "cures" above sound like they'd cause a slipping clutch, not locked up as he describes ??
did you put the correct amount of fibers/plates back in ? 1 too many of either and it will never disengage.
did you reuse the smaller diameter clutch fiber abd wave washer ? was the wave washer inside that fiber ? (posssible it fell down beside it ?)
were the clutch plates soaked in oil for 24 hrs. before installation ?
is the required 650ml of oil in the trans ?
some (my driveline performance 240hd clutch) will "hang" until the engine is warm and it's been cycled a few times
try warming the bike up and pulling the clucth in a few times and report back
when you did the internal rod adjustment and aligned the actuator to the notch on the case, did you turn the rod in till it lightly touched the ball and back it off 1/2 a turn, then tighten the jamb nut with lock-tite ? (while holding the rod from moving)
if that nut backs off even a little, it will not push the pressure plate out enuf to disengage the clutch. and if it backs off and falls down in...expect an implosion !
did you look to see the rod was actually pushing the pressure plate out before putting the cover back on ??
the clutch rod adjustment has to be in one of these vids......
