sounds like the clutch plates are stuck together, I have a fantic section trials bike, and its very common on these bikes, especially when not ridden regularly.
I have to drop the clutch against the wall trick
I forgot about it once and launched the thing through my garage, i have a big tire mark on the back door to prove it!
I would change the oil, and if not fixed, i would disassemble the clutch, and try again

I NOTICE THE MANUAL SUGGESTS JUST REGULAR 10W-30 OIL in the clutch- gearbox maybe this clutch was supposed to work with friction modified oil additives, have always used motorcycle spacefic wet clutch oil. The release mechanism is a ball and ramp device like trident and rocket3, cable and all are fine thanks Lez
Bultaco, SWM and other bikes had or have the same problems.
Take the clutch apart, clean it and lightly slide each plate, in a circular motion on both sides, on a plate glass, or equally hard flat surface, on grinding compound or a 225 grit sand paper. This will flatten the plates.
On reassembly, make sure all springs are tightened equally and the plates in the basket run true. As for oil, I use automatic transmission or 10W30.
Years ago Don MacMillan and I were at Bobo Guzzo's place and Bob wanted to show Don how well his SWM 270 ran, Bob started the bike and clicked it into gear, the bike took off and stopped on his fence, he had pulled the clutch in to no avail and finally the bike stalled after digging in the rear wheel to the axle. I used to run my 1982 SWM with the clutch pulled in until it freed, then it wasn't to bad.
My 2 cents, Yves
