Matpoc, yes, the problem goes worse when oil gets hot, that's why I'm very suspicious than the last 4 liters tins Castrol sintetic 10W50 that I bought is not the same quality as it used to be... I don't know why 
So I'll order Motorex 10W60 rather than 10W50. I chose motorext because I can order it at the same time I order the spare parts (to the same dealer)
So, step by step may be I should try (from cheaper and easy solution to a expensive and complicated one)
1.- Change oil brand. If it doesn't work...
2.- File basket's grooves. If it doesn't work...
3.- Change disc plates and springs. If it doesn't work...
4.- Put the bike into a garbage can
