765rs Clutch Slipping From New

hi just got my new 765RS ,had a 80 miles trip home from dealer , got to 40 miles keeping her under 5k , stopped half way for a rest, got bike on bike after 10 mins I noticed just before 5k revs the clutch starting slipping , anyone else had this happen ,I had to loosen the clutch cable abit when I got home ,there was no free play in it , just hope it did not damage the clutch at all , I told the dealer and they said it was the fully synth oil that was in it ,I thought new bikes had cheaper running in oil in them for the running in, ive had 4 new bikes and never had a clutch slip on any of them ?

 

yeah gave it a abit of slack , seems ok will soon find out after my first service when I can give it abit more in the rev range
