Most common Problem
Is not a problem at all, if you start the bike and pull the clutch you may feel it wanting to go Fwd. thats common because the plates stick. If you pull the clutch put it in gear and rev it a few times that should go away.
Make sure you have clutch play 1/8 of an inch at least. If you ajust the clutch cable to tight it will burn the plates and cause your clutch to slip.
I ajust my clutch all the time, when its cold vs Hot
