I have also gone through this once and then i set the clutch settings and issue was resolved.
Also it has another way to treat and that is you can turn off the bike while in long jam heavy traffic and then start by using self starter switch when the traffic moves. Also remember it may be due to the new clutch cable which gets loose after pressing the clutch continuously and you may get it adjusted and after use of a couple of months; the time will come that the cable will be adjusted forever. So don't be worried.
