Yea, sounds like you've burnt it up!

Here's the thing ...

When you replace the clutch plates (probably friction plates only, not steel plates)
you should also replace the PRESSURE PLATE and Clutch Springs.

What happens when things get HOT is the heat treatment of the springs is lost ... and they SHRiNK! Have your mechanic compare your old springs with a new one.
I'm betting the old one will be shorter ... not good. Springs are cheap. Plates aren't bad and the pressure plate could be reused unless it's bungered up or scored. (you'll see this)

It's a super SIMPLE job, any decent pro mechanic can do the whole job in under 2 hours easy. You can probably order the parts from a Suzuki dealer there in Spain.
WARNING: I would NOT use aftermarket clutch plates or springs ... use only
genuine Suzuki parts. (BEST!) If you have no choice and can't get Suzuki parts ... well, don't expect things to last long.
Mechanics and shop monkeys will push you to buy aftermarket ... they make more money! Don't do it. I am not wild about EBC or Barnett clutch plates.

You can ride it very carefully, don't let it rev up ... stay in lower gear longer, accelerate slow, do not lug it, if it starts to spin up and rev ... back off, slow down. If it gets too hot ... bad expensive things can happen. Limp it to a good bike mech.
